Effect of zeolite topology on the hydrocarbon distribution over bifunctional ZnAlO/SAPO catalysts in syngas conversion

Mengheng Wang et al.

Summary: Recent studies show that bifunctional catalysts of metal oxides and zeolites can control hydrocarbon distribution in syngas conversion. SAPO zeolites' micropore window size primarily determines the distribution, while cage size and reaction conditions only affect it within a narrow range of chain length. Zeolite topology has a similar impact on hydrocarbon distribution in syngas conversion compared to methanol conversion.

Highly dispersed metal doping to ZnZr oxide catalyst for CO2 hydrogenation to methanol: Insight into hydrogen spillover

Di Xu et al.

Summary: The addition of a small amount of Cu into ZnZrOx can enhance the efficiency of CO2 hydrogenation to methanol, with the optimized catalyst showing higher CO2 conversion and methanol yield at comparable methanol selectivity. This improvement is attributed to the enhanced hydrogenation capacity and accelerated transformation of key intermediates caused by hydrogen spillover from well dispersed Cu.

Effect of Sm Doping on CO2-to-Methanol Hydrogenation of Cu/Amorphous-ZrO2 Catalysts

Taihei Yamamura et al.

Summary: This study demonstrates that doping Sm into Cu/a-ZrO2 can increase the number of surface-dispersed Cu2+ species, enhance the dispersion of Cu nanoparticles, and increase the number of active sites, promoting CO2 adsorption and CO activation. However, Sm doping decreases methanol selectivity and leads to Cu sintering, weakening the interaction between Cu and a-ZrO2.
