Ultrasound-assisted synthesis of visible-light-driven Ag/g-C3N4 catalysts in a continuous flow reactor

Hai Zhu et al.

Summary: The study developed an ultrasound-assisted method for the continuous synthesis of visible-light-driven Ag/gC3N4 catalysts with controllable sizes and narrow size distributions. The results showed that the increase of ultrasound output power and the decrease of residence time led to smaller silver nanoparticles and narrower distribution, resulting in higher catalytic activity. Additionally, Ag/g-C3N4 catalysts with higher Ag loading exhibited better catalytic activity despite the bigger size of Ag nanoparticles.

Unraveling the dual defect sites in graphite carbon nitride for ultra-high photocatalytic H2O2 evolution

Xu Zhang et al.

Summary: Defect engineering modified graphite carbon nitride (g-C3N4) with dual defect sites, -C N groups and N vacancies, has been found to significantly enhance the photocatalytic production of H2O2. The dual defect sites form an electron-rich structure and lead to a more localized charge density distribution, which improves light absorption, carrier separation, selectivity, and activity of H2O2 generation. The N vacancies effectively adsorb and activate O-2, while the -C N groups facilitate the adsorption of H+, synergistically promoting H2O2 generation. The modified g-C3N4 achieved a high H2O2 generation rate and apparent quantum efficiency, surpassing previously reported g-C3N4-based photocatalysts.
