Summary: A novel method using methylene blue as a photosensitizer for the homogeneous degradation of methyl orange under visible-light irradiation was proposed. The degradation mechanism involves Type II pathway and Type I photosensitization, and synchronous removal of methyl orange and methylene blue can be achieved by controlling the initial methylene blue concentration. This cost-effective method shows great potential in eliminating methyl orange and methylene blue from wastewater and offers a new strategy for sustainable water treatment.

Summary: In this study, NiAl2O4, NiAl1.98Bi0.02O4, and NiAl1.98Ce0.02O4 were synthesized using the sol-gel method. Doping of larger ions (Ce3+ and Bi3+) into the aluminium ion lattice resulted in an increase in lattice constant and the formation of spherical particles with visible pores. The tailored materials showed a decrease in bandgap, leading to enhanced photocatalytic efficiency. The doped nickel aluminate catalysts exhibited improved degradation efficiency against the tested dyes.

Summary: A series of Bi3+-doped ceria nanoparticles were successfully synthesized and showed effective photocatalytic degradation of methylene blue dye under visible light irradiation. Characterization through crystallography, microscopy, and spectroscopy confirmed the effectiveness of doping in the host lattice, along with the mesoporous nature of the nanoparticles. The shift of band gap energy from UV to visible region resulted in the photo degradation of the dye under visible light.

Summary: This study used TiO2 and cornstalk biochar to prepare biochar-TiO2 composites for treating methyl orange (MO) in water. The composites prepared using biochar generated at 700℃ and a TiO2/biochar mass ratio of 0.75/1 showed the best performance on MO decolorization and mineralization efficiency. Factors such as low pH, low initial MO concentration, and 1 g/L of composite amount added enhanced MO degradation efficiency. The biochar-TiO2 composites were easier to separate from water compared to pure TiO2, benefitting their recycling after application.

Summary: This study used waste sawdust to prepare TiO2/C composites, which were used to effectively degrade methylene blue (MB) under simulated sunlight. The carbon component in the composite significantly enhanced sensitization, resulting in a wider visible light absorption and decreased charge recombination rate. The MB degradation efficiency reached nearly 100% within 30 minutes in the presence of TiO2/C composites, and the material showed sustained performance after multiple cycles. This green and low-cost preparation method offers a sustainable and efficient alternative to reduce the consumption of fossil resources.

Summary: Reduced graphene oxide (rGO)/TiO2 nanocomposites, synthesized through a hydrothermal technique, were used as photocatalysts to effectively degrade methylene blue (MB) in industrial dyestuff wastewater. The degradation efficiency of the nanocomposites for MB was as high as 98.18% at 5wt.% rGO content, 0.4 g L-1 rGO/TiO2 content, pH 6, and 60 mg L-1 MB concentration. The photocatalytic degradation mechanism involved immediate oxidative degradation and the combined action of O-2(center dot-), OH(center dot), and h(+) species. The degradation kinetic of the nanocomposites for MB followed a first-order model under UV irradiation.

Summary: Zinc oxide nanoparticles were successfully synthesized using glycine nitrate solution combustion synthesis. The synthesized nanoparticles exhibited a pure hexagonal wurtzite-like structure of ZnO. They showed effective visible light catalytic activity in the degradation of methylene blue dye, degrading 98% of the dye in 120 minutes with 0.1 g/L of catalyst loading. Photoluminescence studies suggested that the enhanced photocatalytic activity may be attributed to the presence of singly ionized oxygen vacancy or intrinsic defects.

Summary: In this study, a copper and bismuth co-doped CeO2 nanostructure was synthesized using subcritical hydrothermal method for water remediation application. The co-doping of copper and bismuth synergistically improved the conductivity and light-harvesting capabilities of the co-doped CeO2, as confirmed through current-voltage and optical studies. The microstructural, compositional, and morphological information of the photocatalyst were analyzed using powder XRD and spectroscopic techniques. The as-prepared co-doped CeO2-based photocatalyst demonstrated efficient mineralization of the anionic dye methyl orange under solar irradiation, outperforming a CeO2 photocatalyst in terms of effectiveness and rate of dye mineralization. The co-doped CeO2 photocatalyst also exhibited excellent robustness and retained its photocatalytic activity after multiple reusability tests.

Summary: It was found that by increasing the ZnO particle size, while keeping the same Au loading/Au particle size, the activity for methanol formation can be improved, and the selectivity also increases steadily. This is mainly due to the increasing electronic modification of Au interface perimeter sites and the formation of O-vacancy defects in the ZnO lattice.
