It is widely confirmed that Overall water splitting with particulate photocatalysts is the cocatalyst plays a pivotal role in promoting the charge regarded as one of the most promising approaches to convert separation and providing active sites for the redox reactions solar energy into chemical energy in the form of hydrogen in [5–8]. consideration of its advantages of the simplicity and econ- Many kinds of metals, metal oxides, sulfides, and car - omy suitable for large-scale application [1–4].
