Summary: Selective hydrogenation of alpha,beta-unsaturated aldehydes to obtain a high yield of unsaturated alcohols is important in industrial production. However, this is still a great challenge because the hydrogenation of C=C is thermally more favorable than the C=O bond. Various strategies have been developed to optimize catalysts for improving selectivity, but usually at the expense of catalytic activity. In this study, a series of Ir-M alloy nanoparticle catalysts were synthesized using the inert metal inducement strategy. The optimal catalyst, IrCd5, exhibited impressive catalytic performance in the selective hydrogenation of cinnamaldehyde, achieving high conversion and selectivity for cinnamal alcohol compared to the Ir counterpart. This study provides a new avenue for designing bimetal alloy catalysts for the selective hydrogenation of alpha,beta-unsaturated aldehydes.

Summary: The propane dehydrogenation (PDH) performance of non-noble metal Co-based catalysts can be improved with modified Ti-ZSM-5 zeolites as supports. The enhanced performance is attributed to the tuned state of active Co species and surface acid property due to Ti species. The developed Co/Ti-ZSM-5 catalysts exhibit high selectivity and regeneration stability in recycling PDH reactions. By decreasing the Si/Ti ratio of Ti-ZSM-5 zeolites, the Co sites at different interfaces can be tailored, leading to structural evolution of Ti and improved dispersion and chemical state of the Co sites. Additionally, the high Si/Ti ratio in Ti-ZSM-5 zeolites reduces surface acidity, facilitating C3H6 desorption and enhancing selectivity and anti-coke stability.
