Abstract:

To meet the requirements of sustainable development, photoelectric catalytic decomposition of hydrogen in the water, CO₂ reduction and degradation of pollutants, has become the research hot spot due to its predictability of advantage in energy storage and transport. Metal-organic frameworks (MOFs) material with high specific surface area, metal/organic ligand rich, large pore volume, structure and composition of the advantages of adjustable, has great potential in photoelectric catalysis applications. Therefore, this article mainly reviewed the research progress on the application of MOFs materials in the photoelectric catalysis from the three aspects of hydrogen production from water decomposition, CO₂ reduction and organic pollutants degradation. Firstly, the MOFs materials were introduced in the field of catalysis in recent years. Several widely used MOFs catalyst synthesis methods were summarized, and their advantages and disadvantages were compared. Secondly, a few basic mechanisms and the latest research progress in the application of MOF based photoelectric catalyst was introduced in detail respectively. Finally, the role of MOFs materials in optical electrode and the opportunities and challenges in the field of photoelectric catalysis was carried on the brief summary and outlook.

Key words: metal organic framework, photoelectrocatalyst, hydrogen production, CO₂ reduction, degradation of organic pollutants
