Using photoelectrochemical (PEC) water splitting to produce green hydrogen from solar energy is a potentially practical approach. Unfortunately, the slow water oxidation reaction and very low charge ...

This study is led by Prof. Rengui Li (State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences). The distinct charge separation difference has been found ...

When a solid and a liquid come into contact, charged entities on both sides push one another apart. This phenomenon is known as charge separation, and it creates an electric double layer—a layer each ...
