Anion-modulated CoP electrode as bifunctional electrocatalyst for anion-exchange membrane hydrazine-assisted water electrolyser

“…33 Inspired by this, it is ideal to optimize the physicochemical properties of electrode materials through addition of suitable reagents and improving their catalytic performance using a one step electrodeposition process. [34][35][36] However, the development of similar strategies to enhance the catalytic activity of traditional metal phosphides has rarely been reported, and the performance of existing reports still needs to be improved.…”

Interface Engineering of a Hierarchical P-Modified Co/Ni3P Heterostructure for Highly Efficient Water Electrolysis Coupled with Hydrazine Degradation

“…The intrinsic sluggish kinetics of HzOR involves multiple electron transfer and complex evolution pathways, necessitating that elaborate design of advanced materials for HzOR is significant to decrease the energy barrier and accelerate the reaction rate. – Over the past few years, various regulation strategies, such as interface engineering, vacancy design, doping, or morphology regulation, have been developed to promote the electrocatalytic activity of transition metal (TM)-based catalysts (alloy, sulfides, oxyhydroxides, phosphides, and nitrides). – Among them, the construction of TM-based heterostructured electrocatalysts is gradually emerging as one of the important regulatory strategies due to their tunable electronic structures, multiple metal centers, and abundant heterogeneous interfaces. For example, a copper–nickel nitride (Cu 4 N/Ni 3 N) prepared by Mai’s group exhibits an extremely low voltage of 0.24 V at 10 mA cm –2 as well as excellent stability for the hybrid water electrolyzer .…”

Hierarchical Cobalt–Nickel Phosphide/Molybdenum Disulfide Hybrid Electrocatalyst Triggering Efficient Hydrogen Generation in a Wider pH Range

“…The burning of fossil fuels has caused many environmental pollution problems, inspiring the development of green and pollution-free clean energy. Hydrogen, as clean energy with the highest calorific value of combustion, has received significant research interest. − The hydrogen evolution reaction (HER) of water splitting is a promising and valuable approach to produce hydrogen on a large scale. − To improve the energy conversion efficiency, rational utilization of the catalysts to optimize the catalytic performance is critical. Platinum-based materials are considered to be the most effective electrocatalysts for HER. , However, their high costs and scarcity have prevented them from being implemented in commercial systems.…”
