Summary: CuO-ZnO nanocomposite photocatalysts synthesized via a facile co-crystallization process followed by high pressure annealing demonstrated excellent photocatalysis of H-2 gas generation via water splitting as well as methylene blue dye degradation. The unique hierarchical bullet-shaped structure of nanobullets, uniform distribution of CuO nanoparticles, and formation of heterojunction were revealed through morphological analyses, elemental analyses, X-ray photoelectron spectroscopic analysis, and several imaging and spectroscopic techniques. The enhanced photocatalytic activity of the composite samples compared to uncombined ZnO and CuO was attributed to the synergistic migration of charge carriers across the heterojunction.

Summary: The formation of a uniform mesoporous CdS shell on the surface of Sb2S3 nanorods (NRs) via a surface cationic displacement strategy constructs the core-shell Sb2S3@CdS heterojunction with high BET surface area and excellent near-infrared light harvesting capacity. The Sb-S-Cd bonding interaction and van der Waals force significantly enhance the stability and synergy of Sb2S3/CdS heterointerface throughout the entire surface of Sb2S3 NRs, promoting the Sb2S3-to-CdS electron transfer due to the formation of built-in electric field. Therefore, the optimized Sb2S3@CdS catalyst achieves highly enhanced simulated sunlight-driven Cr(VI) reduction and decomplexation of complexed Cr(III), resulting in effective chromium-containing wastewater treatment.

Summary: This study explores the influence of the morphological characteristics of hexagonal cadmium sulfide nanoparticles and nanorods on the photocatalytic performance of hydrogen production. It is found that the size difference between the nanoparticles and nanorods leads to different nanoconfinement effects, affecting the separation and migration kinetics of photoexcitons and thus the catalytic performance. By synthesizing CdS nanoparticles and nanorods and decorating them with single-atomic titanium, two forms of nano-confined systems are constructed. The results show that CdS nanoparticles, under the three-dimensional nanoconfinement dynamics, have a significant inhibitory effect on the migration of photoexcitons, resulting in higher photocatalytic hydrogen production under simulated sunlight conditions.
