Developing robust and highly active non‐precious electrocatalysts for the hydrogen/oxygen evolution reaction (HER/OER) is crucial for the industrialization of hydrogen energy. In this study, a highly active and durable single‐atom W‐doped NiS0.5Se0.5 nanosheet @ NiS0.5Se0.5 nanorod heterostructure (W‐NiS0.5Se0.5) electrocatalyst is prepared. W‐NiS0.5Se0.5 exhibits excellent catalytic activity for...
Exploring earth‐abundant and highly efficient electrocatalysts is critical for further development of water electrolyzer systems. Integrating bifunctional catalytically active sites into one multi‐component might greatly improve the overall water‐splitting performance. In this work, amorphous NiO nanosheets coupled with ultrafine Ni and MoO3 nanoparticles (MoO3/Ni–NiO), which contains two heterostructures...
The increase of reaction temperature of electrocatalysts is regarded as an efficient method to improve the oxygen evolution reaction (OER) activity. Herein, it is reported that the electrocatalytic performance of dual functional (i.e., electrocatalytic and photothermal functions) Co3O4 can be dramatically improved via its photothermal effect. The operating temperature of the Co3O4 electrode is elevated...
