China University of Science and Technology developed a new high-performance, low-cost new ternary nanosheet electrocatalyst

The Yu Shuhong team of the University of Science and Technology of China and the team of Gao Minrui have developed a new high-performance, low-cost new ternary nanosheet electrocatalyst. It exhibits industrial-grade excellent hydrogen production potential for electrolyzed water. "German Applied Chemistry" recently published the results.

In recent years, the international academic community has made remarkable progress in the design and preparation of fully hydrolyzed electrode catalysts. However, finding a non-precious metal electrocatalyst capable of simultaneously exhibiting high activity and high stability in a neutral water electrolyte is still a challenge.

The researchers designed and successfully prepared nickel-doped phosphide ternary nanosheet electrocatalysts by electrochemical deposition and solid phase phosphating. It exhibits excellent water reduction and oxidative electrocatalytic activity and stability under neutral conditions.

The experimenter used this ternary material as the cathode and anode of a neutral water total decomposition electrolytic cell, and found that its performance is superior to that of an electrolytic cell prepared by using a commercial precious metal material as an electrode.

According to reports, 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.
