The water-gas shift (WGS) reaction (where carbon monoxide plus water yields dihydrogen and dioxide) is an essential process for hydrogen generation removal in various energy-related chemical operations. This equilibrium-limited favored at a low working temperature. Potential application fuel cells also requires WGS catalyst to be highly active, stable, energy-efficient match the temperature of on-site consumption units.

A series of novel CoFe-based catalysts are successfully fabricated by hydrogen reduction CoFeAl layered-double-hydroxide (LDH) nanosheets at 300-700 °C. The chemical composition and morphology the reaction products (denoted herein as CoFe-x) highly dependent on temperature (x). CO2 hydrogenation experiments conducted CoFe-x under UV-vis excitation. With increasing LDH-nanosheet temperature, show a progressive selectivity shift from CO to CH4 , eventually high-value hydrocarbons (C2+ )....
Abstract Zn‐ and Na‐modulated Fe catalysts were fabricated by a simple coprecipitation/washing method. Zn greatly changed the size of iron species, serving as structural promoter, while existence Na on surface catalyst alters electronic structure, making very active for CO activation. Most importantly, structure suppresses hydrogenation double bonds promotes desorption products, which renders unexpectedly reactive toward alkenes—especially C 5+ alkenes (with more than 50% selectivity in...
Although great progress has been made in artificial enzyme engineering, their catalytic performance is far from satisfactory as alternatives of natural enzymes.

Atomization Pt NPs makes metal sites fully exposed results engineerable structural electronic properties, thereby leading dramatically...
