Electrolytic water hydrogen catalyst breakthrough

Recently, researchers from the University of Science and Technology of China have cooperated to develop a new high-performance and low-cost ternary nanosheet electrocatalyst, which demonstrates the industrial hydrogen-producing potential of electrolyzed water.

The researchers used electrochemical deposition and solid-phase phosphating two-step reaction to design and successfully prepare nickel-doped phosphide ternary nanosheet electrocatalysts, which simultaneously exhibited excellent water reduction and oxidative electrocatalysis under neutral conditions. Activity and stability. The experimenter used this ternary material as the cathode and anode of the neutral water total decomposition electrolytic cell, and found that its performance is superior to that of the electrolytic cell prepared by using commercial precious metal materials as electrodes, demonstrating the potential of industrial grade electrolyzed water to produce hydrogen. This work provides a new idea for the development of cheap ternary transition metal phosphide as an electrode for hydrogen production in neutral water electrolysis, and shows potential commercial application prospects.

The international academic community has made remarkable progress in the design and preparation of fully hydrolyzed electrode catalysts, but it is still a challenge to find non-precious metal electrocatalysts that exhibit high activity and high stability in neutral water electrolytes.
