Defective g-C3N4/covalent organic framework van der Waals heterojunction toward highly efficient S-scheme CO2 photoreduction

Jiangpeng Wang et al.

Summary: This study introduces a novel vdW heterojunction composite of g-C3N4 with nitrogen vacancies and Tp-Tta COF, showing effective interface contact area and improved photocatalytic CO2 reduction performance. The presence of nitrogen vacancies widens the Fermi level gap between g-C3N4 and Tp-Tta COF, leading to enhanced carrier recombination and higher photocatalytic activity and stability. The efficient electron transfer and CO2 affinity of Tp-Tta contribute to the enhanced CO selectivity in the S-scheme heterojunction photocatalyst design for CO2 reduction.

Construction of S-scheme CdS/g-C3N4 nanocomposite with improved visible-light photocatalytic degradation of methylene blue

Kim Nguyen Van et al.

Summary: In this study, CdS/g-C3N4 composites were successfully prepared and showed enhanced photocatalytic activity in the degradation of methylene blue under visible light. The improved activity was attributed to effective photo-induced electron-hole separation and the main contribution of oxidative hydroxyl radicals. Through a S-scheme model, the depletion of photo-induced holes on CdS was clarified as the reason for the enhancement in resistance to photocorrosion of the composites.
