Laser Synthesis in Liquid Induced Lattice Distortion in PtFeSn/Activated Carbon for Enhanced Methylcyclohexane Dehydrogenation.

Methylcyclohexane (MCH) has emerged as one of the most promising liquid organic hydrogen carriers (LOHCs) for H storage and long-distance transportation. Developing efficient, selective, and stable catalysts for MCH dehydrogenation is essential to make the process viable for practical applications. In this study, a platinum-iron-tin alloy supported on activated carbon (PtFeSn/AC) is reported, prepared via laser synthesis in liquid (LSL), exhibiting excellent dehydrogenation performance.

Ru Single Atom Dispersed Cu Nanoparticle with Dual Sites Enables Outstanding Photocatalytic CO Reduction.

Cu-based catalysts are promising candidates for CO reduction owing to the favorable energetics of Cu sites for CO adsorption and transformation. However, CO reduction involving insurmountable activation barriers and various byproducts remains a significant challenge to achieve high activity and selectivity. Herein, a photocatalyst constructed with single-Ru-site-on-Cu-nanoparticle on BiTiO exhibits exceptional activity and selectivity for CO conversion to CO.
