Rhodium catalyst on alumina (Rh/Al₂O₃ catalyst)
Rhodium on alumina (Rh/Al₂O₃) is a high-performance heterogeneous catalyst widely used in hydrogenation, syngas production, and automotive emission control. The alumina support enhances rhodium dispersion, improving catalytic activity and thermal stability in petrochemical and environmental applications. This noble metal catalyst is ideal for methane reforming, hydroformylation, and fine chemical synthesis due to its selectivity and durability.
Our rhodium on alumina catalyst (Rh/Al₂O₃) features high-purity γ-Al₂O₃ support (≥200 m²/g surface area) with adjustable Rh loading (1-5 wt%), 20-50 nm particle size, and excellent thermal stability (≤600°C). Delivers >50% Rh dispersion and >90% CH₄ conversion in steam reforming, ideal for syngas production, hydrogenation, and emission control. Customizable in pore size (3-15 nm) and form (pellet/sphere/honeycomb) for specialized applications.

Application of Rh/Al2O3 catalyst
Rhodium on alumina (Rh/Al₂O₃) catalysts are widely used in automotive catalytic converters to reduce NOx, CO, and hydrocarbon emissions. They also play a key role in hydrogenation reactions, such as converting benzene to cyclohexane for nylon production. Additionally, Rh/Al₂O₃ is used in syngas conversion processes to produce oxygenates like ethanol. Its high activity and thermal stability make it valuable in industrial and environmental applications.

Mechanistic Study of Low-Temperature CO2 Hydrogenation over Modified Rh/Al2O3 Catalysts
Abstract: The hydrogenation of CO2 on Rh/Al2O3 catalysts modified with Ni and K was studied by in situ and operando DRIFTS spectroscopy comprising transient and isotopic exchange experiments to study the influence of this modification on the catalytic performance in CO and methane formation at 250–350 °C and to gain mechanistic insight.
