Summary: The development of efficient bifunctional catalysts for water electrolysis, especially at large current density, is of great significance. In this study, a heterostructure catalyst composed of FeNi3 nanoparticles and FeWO4 nanosheets was prepared. It showed good activity for both oxygen evolution reaction and hydrogen evolution reaction, requiring only 1.43 V and -43 mV to achieve & PLUSMN;10 mA cm-2, respectively. Moreover, the catalyst demonstrated robust stability, working for 100 hours at 1000 mA cm-2 under simulated industrial conditions. The excellent performance can be attributed to the heterostructure facilitating electron transfer at the interface and the hierarchical array structure exposing more active areas and accelerating ion and charge transport.

Summary: In this study, hierarchical nanosheets of NiCoP@FeNi LDH were prepared on nickel foam using a hydrothermal-phosphorization-electrodeposition process as non-noble metal electrocatalysts for hydrogen production at high current density (HCD). The NiCoP@FeNi LDH/NF showed overpotentials of only 195 and 230 mV for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), respectively, reaching 10 0 0 mA cm-2. For overall water splitting, only 1.70 V was required at 10 0 0 mA cm-2. This work provides valuable insight for industrial-scale hydrogen production at HCD.

Summary: Selective hydrogenation of phenol to cyclohexanone is studied to understand the catalytic mechanism and selectivity discrepancy on noble metal catalysts. Results show that different reaction pathways converge to the formation of cyclohexanone under mild conditions. The selectivity discrepancy depends on the activity for cyclohexanone sequential hydrogenation, which is influenced by hydrogenation energy barrier and competitive chemisorption between phenol and cyclohexanone.
