Summary: The proper design of interfacial contact of heterojunction photocatalyst is crucial for the transfer/separation of interfacial charge carriers. In this study, KBiO3/g-C3N4 Z-scheme heterojunction photocatalysts were successfully synthesized, resulting in significantly improved photocatalytic performance for the degradation of crystal violet and phenol. The enhancement was attributed to the internal electric field formed by the Z-scheme photocatalyst, leading to enhanced visible light absorption and inhibition of electron-hole recombination.

Summary: Photocatalysis is a promising technology for addressing the environmental crisis. One of the most representative photocatalysts is graphitic carbon nitride (g-C3N4), known for its stability, cost-effectiveness, facile synthesis procedure, and absorption properties in visible light. However, the original g-C3N4 still demonstrates low photoactivity due to quick recombination of photo-induced electron-hole pairs. To overcome this limitation, Z-scheme photocatalysts based on g-C3N4 are considered superior alternatives, as they have the same band configuration but a different charge carrier recombination mechanism.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
