Ultrathin NiCo Bimetallic Molybdate Nanosheets Coated CuOx Nanotubes: Heterostructure and Bimetallic Synergistic Optimization of the Active Site for Highly Efficient Overall Water Splitting (Adv. Energy Mater. 41/2021)

Water Splitting In article number 2102361, Xiaojun Zhang and co‐workers report the development of ultrathin bimetallic molybdate nanosheets that are evenly deposited on CuOx hollow nanotubes on a copper foam substrate to form a hierarchical heterostructure (CoNiMoO4/CuOx/CF). The material is used as an efficient bifunctional electrocatalyst for overall water splitting. The introduction of Ni to form a bimetallic molybdate and CuOx heterostructure design can be optimized via Co cations to ensure the best possible electronic structure of the catalytic center.
