Eradicating the Photogenerated Holes in a Photocatalyst-Microbe Hybrid System: A Review.

Finding advanced technologies to store solar energy in chemical bonds efficiently is of great significance for the sustainable development of our society. The recently reported photocatalyst-microbe hybrid (PMH) system couples photocatalysts intimately with microbes and endows heterotrophic microbes with light-harvesting capacity. Generally, when PMH systems are exposed to light, photocatalytic reactions occur on the surface of photocatalysts and the photogenerated electrons enter microbial cells to promote the generation of energy carriers (such as nicotinamide adenine dinucleotide phosphate hydrogen and adenosine triphosphate) and the following chemical synthesis.

CDs-g-CN-oleaginous yeast hybrid system: Microbial lipid synthesis and fermentation residual reutilization.

The utilization of solar energy and fast-growing heterotrophic microbes for biofuel production has been recognized as a promising approach to achieve carbon neutrality and address energy crisis. In this work, we synthesized different kinds of photocatalysts based on graphitic carbon nitride (g-CN). We found that carbon dots modified-graphitic carbon nitride (CDs-g-CN) showed the highest photocatalytic activity.
