Summary: In this study, a series of ternary composites were synthesized by integrating 7% silver-mixed ZnO nanoparticles with sulfur-doped graphitic carbon nitride in different proportions. The unique ternary composite between Ag/ZnO and S-g-C3N4 was found to generate a large number of catalytic active sites for photocatalytic degradation. The synergistic effects of the ternary composite enhanced photocatalytic activity and demonstrated successful photo-corrosion resistance.

Summary: Graphitic carbon nitride (g-C3N4) and CuO nanoparticles doped g-C3N4 (Cu-g-C3N4) exhibit high photocatalytic antialgal activities against harmful algae, with Cu-g-C3N4 showing stronger activity due to better aggregation and higher light utilization efficiency. The presence of humic acid (HA) inhibits the antialgal activity of g-C3N4 but has no effect on Cu-g-C3N4, suggesting that CuO nanoparticles in Cu-g-C3N4 play a role in mitigating the inhibition effects of HA. This study provides insights into the inhibition mechanisms of natural organic matter on g-C3N4 photocatalytic antialgal activity and optimization strategies for environmental applications.

Summary: The study investigated the dynamics of hole transfer from Pt-loaded sol-gel-prepared graphitic carbon nitride photocatalyst, using different adsorbed hole acceptors and a sacrificial agent. A significant increase in H-2 production was achieved by employing phenothiazine as the hole acceptor, with continuous H-2 production for 3 days. The charge-transfer dynamics of the photocatalytic process in the presence of hole acceptors were examined through time-resolved photoluminescence and in situ electron paramagnetic resonance studies.

Summary: Graphitic carbon nitride (CN) incorporated with mixed-valence molybdenum ion was prepared via in-situ copolymerization for enhanced photocatalytic H2 evolution. The introduced mixed-valence Mo species, with content tunable by adjusting MoCl5, contributed to narrowed band gap, increased electron density, and elevated electron motion kinetics, resulting in extended visible light response and improved charge separation and transport. The optimized CN-Mo photocatalyst with 0.41 wt% Mo ions exhibited a robust H2 production activity of 1.44 mmol h-1 g-1, 18 times higher than the pristine counterpart.

Summary: A new one-step thermal polycondensation process is reported to produce crinkly graphitic carbon nitride nanosheets (CGCNNs) through supramolecular preorganization using a mixture of urea and melamine. Systematical studies show that the newly developed CGCNNs exhibit significantly enhanced optical absorption, widened bandgap, increased Hall mobility, and carrier density compared to its bulk counterpart, leading to a 7-fold improvement in photocatalytic hydrogen production rate. Na doping of CGCNNs further enhances its photocatalytic activity, resulting in an impressive hydrogen production rate approximately 10.5 times higher than its bulk counterpart, along with an apparent quantum efficiency of 19.12% at 420 nm.

Summary: In this study, a hybrid plasmonic/semiconductor material was fabricated by combining the chemical bath deposition of zinc oxide nanowires (ZnONWs) with the physical vapor deposition of aluminum nanostructures (AlNSs). The morphological and optical properties of the hybrid material fabricated at different temperatures and thicknesses were investigated. By adjusting the deposition and annealing parameters, the size distribution of the aluminum nanostructures could be tuned, leading to enhanced photoluminescence response and photocatalytic activity.
