Recent advances in porous materials for photocatalytic NADH regeneration

Photocatalytic NADH regeneration is a promising technology for solving the problems of the practical applications of energy and coenzymes. Porous photocatalysts have superior performances in light absorption, molecular diffusion, and charge separation and migration due to their unique microstructural advantages. In this paper, we review the recent progress on porous photocatalysts for photocatalytic NADH regeneration applications, including g-C3N4, COFs, MOFs, CMPs, and transition metal compounds. We firstly emphasize the influence of their special structural advantages on the photocatalytic reaction processes, including light absorption properties, band structure, carrier migration, and surface active sites. Furthermore, we categorize the synthesis methods commonly employed for these porous materials. This review systematically summarizes the research progress and achievements of porous photocatalysts for photocatalytic NADH regeneration. Their photocatalytic properties and the mechanism of the catalytic system to improve the NADH regeneration efficiency are described. Finally, we discuss the future development directions aimed at further enhancing the performance of photocatalysts and catalytic systems, hoping to advance the application of these emerging porous materials in the field of photocatalysis. This review focuses on recent research progress on porous photocatalysts (e.g., g-C3N4, COFs, MOFs, CMPs, and transition metal compounds) for photocatalytic NADH regeneration.
