Abstract

Abstract : A versatile and efficient cocatalyst based on amorphous Co species (a-Co-E) is reported, and various Bi-based semiconductors loaded with a-Co-E exhibit impressively higher photocatalytic O2 evolution activity than their CoO x -loaded counterparts. Abstract : Cocatalysts play an important role in converting solar energy into chemical energy for photocatalytic water splitting. Herein, a versatile and efficient cocatalyst based on amorphous Co species (a-Co-E) is synthesized through thermal treatment of a Co–ethylene diamine tetraacetic acid complex in air at 300 °C. Various Bi-based semiconductors loaded with the a-Co-E cocatalyst exhibit an impressively higher photocatalytic O2 evolution rate than their CoO x -loaded counterparts.
