Magnetic field-enhanced photoelectrochemical water splitting of Co3O4/TiO2 for efficient oxygen evolution
Effective separation of photogenerated carriers plays a vital role in governing the efficiency of photo-electrocatalytic reactions. However, the advancement in enhancing the intrinsic carrier separation efficiency of semiconductors has shown limited progress. Herein, we reported the use of a magneti...
