Research progress of photocatalyst application in microorganism hybrid system for carbon conversion
Combining photocatalysts with photo-excited properties and microorganisms with specific biological pathways for carbon fixation to construct the photocatalyst-microorganism hybrid system will achieve complementary advantages in solar energy capture,catalytic activity and selectivity.Different types of photocatalyst have huge differences in light absorption characteristic and photocatalytic performance.This paper summarized the hybrid systems for carbon conversion composed of metal containing,nonmetal-based,or composite photocatalysts with microorganisms,and compared key factors such as binding methods,photocatalyst action pathways,the products and efficiencies of carbon conversion.For CdS photocatalyst firstly combined with microorganisms,its development process for the generations of acetic acid,methane,C2+ products,and the process of composite modification were systematically expounded.The key basis of interfacial charge transfer for hybrid system was analyzed.The research methods,existing achievements and problems were summarized.The challenges and development trends of photocatalyst applied in microorganism hybrid system for carbon conversion were analyzed.
