High-entropy alloys (HEAs), which are defined as near-equimolar of five or more elements, attracting ever increasing attention because the unique properties in a variety applications. Recently, HEAs have already exhibited remarkable catalytic performance toward several thermal-driven and electrocatalytic reactions. not only regulate electronic geometric structures to large degree but also serve platform construct catalysts with unexpected performance. Herein, recent advances regarding...
Abstract Rh-based heterogeneous catalysts generally have limited selectivity relative to their homogeneous counterparts in hydroformylation reactions despite of the convenience catalyst separation catalysis. Here, we develop CoO-supported Rh single-atom (Rh/CoO) with remarkable activity and towards propene hydroformylation. By increasing mass loading, isolated atoms switch aggregated clusters different atomicity. During hydroformylation, Rh/CoO achieves optimal 94.4% for butyraldehyde...
Abstract Rechargeable aqueous zinc‐ion batteries (ZIBs) with high safety and low‐cost are highly desirable for grid‐scale energy storage, yet the storage mechanisms in current cathode materials still complicated unclear. Hence, several sodium vanadates NaV 3 O 8 ‐type layered structure (e.g., Na 5 V 12 32 HNaV 6 16 ·4H 2 O) β‐Na 0.33 tunneled 0.76 15 ) constructed storage/release behaviors of Zn 2+ ions deeply investigated these two typical structures. It should be mentioned that 2D more...
Safe, inexpensive aqueous zinc-ion batteries (AZIBs) are regarded as promising energy storage devices. However, they still face issues, including dissolution and collapse of the cathode well H2 evolution growth Zn dendrites on anode. Herein, we simultaneously regulate cations anions in electrolyte for high-capacity, high-stability zinc–vanadium (Zn–V) based a bimetallic cation-doped Na0.33K0.1V2O5⋅nH2O cathode. We demonstrate that Na+ cations suppress restrain dendrite anode via an...
Abstract Supported metal nanocrystals have exhibited remarkable catalytic performance in hydrogen generation reactions, which is influenced and even determined by their supports. Accordingly, it of fundamental importance to determine the direct relationship between metal–support interactions. Herein, we provide a quantitative profile for exploring interactions considering highest occupied state single‐atom catalysts.

Moreover, infrared reflection...
Single-atom catalysts exhibit high selectivity in hydrogenation due to their isolated active sites, which ensure uniform adsorption configurations of substrate molecules. Compared with the achievement catalytic selectivity, there is still a long way go exploiting activity single-atom catalysts. Herein, we developed highly and selective by embedding Pt single atoms surface Ni nanocrystals (denoted as Pt1/Ni nanocrystals). During 3-nitrostyrene, TOF numbers based on reached ∼1800 h–1 under 3...

Abstract As a promising hydrogen carrier, formic acid (HCOOH) is renewable, safe and nontoxic. Although noble-metal-based catalysts have exhibited excellent activity in HCOOH dehydrogenation, developing non-noble-metal heterogeneous with high efficiency remains great challenge. Here, we modulate oxygen coverage on the surface of Ti 3 C 2 T x MXenes to boost catalytic toward dehydrogenation. Impressively, after treating air at 250 °C (Ti -250) significantly increase amount atoms without...
