CeO2 decorated bimetallic phosphide nanosheet as efficient catalyst towards water splitting reaction
Developing low-cost and high-performance electrocatalysts for water splitting is crucial for hydrogen production. In this study, a high-performance hydrogen and oxygen evolution reaction (HER/OER) bifunctional electrocatalyst is developed by introducing oxygen-deficient CeO2 nanoparticles on (Ni, Co)2P nanosheets. The introduction of defective CeO2 modulates the electronic structure of the CeO2@(Ni, Co)2P/NF interface, which offers a synergistic effect promoting the HER/OER reaction in the alkaline water splitting process. Specifically, the CeO2@(Ni, Co)2P/NF electrode exhibits an overpotential of 151 mV for HER and 257 mV for OER at current density of 100 mA·cm−2. In the overall water electrolysis test, it exhibits excellent stability performance at a cell voltage of 1.70 V around 100 mA·cm−2. This work shows an alternative strategy for the development of active bifunctional water splitting electrocatalysts.
期刊介绍：
The Journal of Electroanalytical Chemistry is the foremost international journal devoted to the interdisciplinary subject of electrochemistry in all its aspects, theoretical as well as applied.
Electrochemistry is a wide ranging area that is in a state of continuous evolution. Rather than compiling a long list of topics covered by the Journal, the editors would like to draw particular attention to the key issues of novelty, topicality and quality. Papers should present new and interesting electrochemical science in a way that is accessible to the reader. The presentation and discussion should be at a level that is consistent with the international status of the Journal. Reports describing the application of well-established techniques to problems that are essentially technical will not be accepted. Similarly, papers that report observations but fail to provide adequate interpretation will be rejected by the Editors. Papers dealing with technical electrochemistry should be submitted to other specialist journals unless the authors can show that their work provides substantially new insights into electrochemical processes.
