What is it about?

Highly active, durable and inexpensive oxygen evolution reaction (OER) catalysts are crucial for achieving practical and high-efficiency water splitting. Herein, hierarchical interconnected NixCo1-xOOH nanosheet arrays supported on TiO2/Ti substrate have been fabricated through a facile photodeposition method. The as-obtained NixCo1-xOOH nanosheet arrays show superior OER catalysis performance.

Why is it important?

We report an original photodeposition strategy for the fabrication of NixCo1-xOOH/TiO2 heterostructure nanosheet arrays with superior electrocatalytic performance for oxygen evolution reaction. Our study provides an alternative approach for the rational design of highly active and promising OER electrocatalysts.


We report a novel photodeposition method for the fabrication of highly active, durable and inexpensive oxygen evolution reaction (OER) catalysts. Our work provides direct guidelines and opens up a new route to design and tune the morphology and electronic structure of electrocatalysts to obtain high-efficiency catalyst for renewable energy storage and conversion.
