Abstract Single‐atom alloys (SAAs), combining the advantages of single‐atom and nanoparticles (NPs), play an extremely significant role in field heterogeneous catalysis. Nevertheless, understanding catalytic mechanism SAAs catalysis reactions remains a challenge compared with single atoms NPs. Herein, ruthenium‐nickel (RuNi ) synthesized by embedding atomically dispersed Ru Ni NPs are anchored on two‐dimensional Ti 3 C 2 T x MXene. The RuNi SAA‐3 −Ti catalysts exhibit unprecedented activity...

An intriguing Hamamelis-like structure of K2Ti6O13 with branches 10–20 nm in length is synthesized by alkali treatment Ti3C2 MXene. It exhibits strong catalytic activity for hydrogen desorption from MgH2. The initial dehydrogenation temperature (175 °C) a composite MgH2 5 wt % 112 °C below that pristine Isothermal analysis indicates the releases 6.7 at 280 within 3 min, and 2.7 being released 200 °C. activation energy this material (105.67 kJ mol–1) 69.67 mol–1 lower than Its...
Hydrogen is an ideal clean, nontoxic, and abundant energy carrier with incomparable potential development value. At present, the electrochemical hydrogen evolution reaction (HER) release of from storage materials [e.g., ammonia borane (AB)] are two most promising clean efficient production methods. The a catalyst suitable for both processes will reduce use resources achieve goals one product. Although many catalysts have been studied to promote these reactions, unified reactions rarely...
Creating active sites to improve the mass activity and durability of metal catalysts by elucidating relationship between support is a major challenge. In this study, ultrafine palladium nanoparticles (Pd NPs) were supported on alkalized Ti3C2 (alk-Ti3C2) obtain catalytically interfacial ensemble. The catalyst Pd/alk-Ti3C2 with Pd loading 1.0 wt % exhibited highest in ammonia borane (AB) hydrolysis reaction, an initial turnover frequency 230.6 min–1. A comprehensive analysis revealed that...
