Gold and silver prices increased over the course of 2021, but these did not grow as fast as the prices of iridium and, especially, rhodium. According to a comparison of price indices, the price for rhodium - a precious metal similar to platinum and used especially in catalytic converters of cars - was ten times higher in April 2021 than it was in January 2019. The price hike for rhodium was apparently caused by coronavirus-related lockdowns implemented in South Africa, where mining companies had to close for several weeks.

As of May 2025, it was estimated that the global supply of rhodium stood at approximately 691,000 ounces. Rhodium is considered one of the rarest and most valuable metals in the world. Rhodium: the rare PGM Rhodium is a silver-colored platinum group metal (PGM) that is highly reflective and resistant to corrosion and oxidation. Platinum group metals include rhodium, platinum, ruthenium, iridium, osmium, and palladium. Rhodium is the rarest metal in the platinum family and occurs in the Earth’s crust at a rate of around one part per 200 million. It is primarily used in catalytic converters to clean motor emissions or as a finishing metal for jewelry. Despite having a stable supply globally, the demand for rhodium has been increasing over time.

The syngas-to-ethanol (StE) reaction is a promising alternative route to ethanol from fossil and nonfossil carbon resources. Rh-based catalysts offer the highest ethanol yields so far but suffer from low to moderate CO conversion and high methane selectivity. Despite serious research efforts, ethanol rates and selectivities still need to be improved for industrial application. Current research focuses mainly on improving Rh-based catalysts by the addition of one or usually several promoters. Likewise, peak performance marks have been published readily without considering the catalyst’s long-term stability, and as a consequence, a lack of spent sample characterization still exists. All these circumstances limit our fundamental understanding of promoter effects hampering a rational design of new catalysts. However, an improvement of existing or the development of new catalytic systems is required before the conversion of StE can be economically feasible. Moreover, the drastically increased Rh price over the past five years necessitates the search for an alternative active metal. Still, the replacement of Rh seems to be challenging, although promising results have been achieved by modifying methanol and Fischer-Tropsch synthesis catalysts. Especially, the formation of higher alcohols and oxygenates are often not evitable over Rh-free catalysts. Thus, lowering the Rh content is required rather than replacing Rh in its entirety to develop cost-efficient ethanol synthesis catalysts. An in-depth understanding of Rh’s intrinsic reactivity and the influence of promoters might lead to new strategies for decreasing the Rh content. For this reason, this thesis aims to provide a holistic view of the crucial interplay of Rh–promoter interactions, reaction conditions, and reaction times. The thesis is based on three independent publications covering metal-organic synthesis approaches, detailed catalyst characterizations, formation phase studies, and long-term catalytic investigations. Before more sophisticated catalyst design strategies became viable, specific promoter effects in traditionally prepared Rh-based catalysts needed to be clarified. On this account, a comprehensive study about the stability and formation of Mn- and Fe-promoted Rh/SiO2 catalysts from metal nitrates has been conducted (Paper 1). Four different catalysts were systematically investigated in four different states: calcined, reduced, after long-term catalytic study (>22 days on stream), and after a high-temperature investigation (up to 320 °C). The thorough analysis of each catalyst in the different states led to the identification of specific promoter effects: Fe serves as an electronic modifier on Rh/SiO2 through in situ RhFe nanoalloy formation, whereas MnO is more likely a structural modifier and does not substantially change Rh’s intrinsic product spectrum. In both cases, RhFe nanoalloy formation or creation of Rh–MnO interfacial sites, a close proximity of Rh and the promoter is required. For this reason, a synthesis approach based on molecular single-source precursors (SSP) has been developed using hetero-bimetallic compounds with predefined Rh–Me (Me = Fe or Mn) bonds. Paper 2 highlighted that the SSP approach is a compelling synthesis route toward well-defined bimetallic catalysts, as the Rh–MnO interface could be effectively tuned using a novel Rh3Mn3 carbonyl cluster as SSP. The increase in interfacial sites led to a significantly enhanced ethanol selectivity ranging among the best Rh-based catalysts reported in CO hydrogenation. This SSP approach has been further applied to investigate the formation phase of a RhFeOx/SiO2 model catalyst (Paper 3), as the prevailing nanostructure and the role of RhFe nanoalloys have been controversially discussed in past literature. An extended catalyst characterization before and after the critical formation phase (>140 h on stream) allowed to ascribe a drastic decrease in ethanol formation to a structural change from an unalloyed RhFeOx to an alloyed RhFe/FeOx nanostructure. This investigation explains the great variation of reported catalytic results of RhFe catalysts. Likewise, the relevance of formation phase studies has been demonstrated. Besides specific promoter effects, the stability of Rh-based catalysts over time-on-stream has been addressed by the three related publications. All Rh-based catalysts deactivated within an initial period of 80–120 h on stream depending on catalyst composition and synthesis approach. This deactivation behavior of Rh-based catalysts has not been reported yet. The thorough characterization of the unpromoted and promoted Rh/SiO2 catalysts suggested particle growth through CO-induced sintering, similar to Ostwald ripening reported for Co-based Fischer-Tropsch catalysts. In brief, this thesis demonstrated that Rh-based catalysts undergo significant changes under the influence of high-pressure synthesis gas conditions over time-on-stream. These changes in catalyst structure, morphology, and chemical state have a vital impact on the reactivity and stability of Rh-based catalysts. Whereas current research delivered a more static view on Rh’s reactivity, this work addresses current needs in understanding the stability of Rh-based catalysts and the formation of Rh–promoter interactions under process-relevant reaction conditions. This profound knowledge might serve as a basis for the synthesis of new Rh-based catalysts and might provide the opportunity to lower the Rh content while retaining or even enhancing Rh’s catalytic reactivity.

We here report the rates of water substitution by methanol-d4 for four new oxo-centered trinuclear rhodium(III) clusters with different carboxylate-bridging ligands, [Rh3(μ3-O)(μ-O2CR)6(OH2)3]+ (R = CH2CH3, CH2CH2Cl, CH2Cl, and CHCl2), and [Rh3(μ3-O)(μ-O2CCH3)6(OH2)3]+. By varying the R group alkyl chain, water substitution rates were found to span almost 3 orders of magnitude (k298K = 1.2 × 10-2−2.3 × 10-5 s-1) and reflect the following trend R = CH2CH3 > CH3 > CH2CH2Cl > CH2Cl > CHCl2. Activation parameters for substitution point toward a dissociative activation pathway (ΔH⧧ = 99−115 kJ mol-1; ΔS⧧ = 48−52 J mol-1 K-1), indicating that there is little association with the incoming methanol molecule during the formation of the transition-state complex. Because the mechanism for substitution in all five trimers has a considerable dissociative character, substitution rates are likely very similar to water exchange rates. These data suggest that the kinetic reactivity of the ligated waters is heavily influenced by the inductive ability of the aliphatic substituents, but yet the mechanism of substitution remains virtually unchanged. Structural data are also reported for the four new rhodium(III) trimer salts as well as 103Rh NMR spectra. We find that 103Rh NMR chemical shifts span more than 200 ppm and mirror the same reactivity trend found for the rates of water substitution (103Rh δ (9406−9620 ppm):  R = CH2CH3 < CH3 < CH2CH2Cl < CH2Cl < CHCl2). Taken together, these data suggest a means for estimating water exchange rates for other oxo-centered rhodium(III) trimers from chemical shift data alone.

Twelve chiral bis-3,4-diazaphospholane ligands and six alkene substrates (styrene, vinyl acetate, allyloxy-tert-butyldimethylsilane, (E)-1-phenyl-1,3-butadiene, 2,3-dihydrofuran, and 2,5-dihydrofuran) probe the influence of steric bulk on the activity and selectivity of asymmetric hydroformylation (AHF) catalysts. Reaction of an enantiopure bisdiazaphospholane tetraacyl fluoride with primary or secondary amines yields a small library of tetracarboxamides. For all six substrates, manipulation of reaction conditions and bisdiazaphospholane ligands enables state-of-the-art performance (90% or higher ee, good regioselectivity, and high turnover rates). For the nondihydrofuran substrates, the previously reported ligand, (S,S)-2, is generally most effective. However, optimal regio- and enantioselective hydroformylation of 2,3-dihydrofuran (up to 3.8:1 α-isomer/β-isomer ratio and 90% ee for the α-isomer) and 2,5-dihydrofuran (up to
