Summary: Various pesticides and organic compounds generated as a result of rapid industrialization and pharmaceutical companies pose a major threat to the environment. Novel photocatalysts based on zinc oxide and titanium oxide exhibit great potential towards absorption of these organic pollutants from wastewater. However, several limitations like poor affinity, particle agglomeration, high band gap, and recovery issues need to be addressed to enhance their efficiency and make them cost effective and sustainable.

Summary: A novel ZnO@PDA/CuPOMs nanocomposite was synthesized and showed high-efficiency photocatalytic degradation of tetracycline (TC) and outstanding antibacterial activities against various bacteria. The nanocomposite retained 80% removal efficiency in the presence of competing species and exhibited a synergistic effect between ZnO@PDA and Cu-POMs for antibacterial action.

Summary: In this study, TiO2 and ZnO nanoparticles of different sizes and crystallographic configuration were used to protect wood surfaces from UV radiation. The size and photoactivity of the nanoparticles were measured, and the effects on wood surfaces were evaluated after UV irradiation. The results showed that nanoparticles with lower photoactivity were more effective in reducing the impact of UV radiation on wood surfaces, and smaller nanoparticles were more effective in reducing photochemical reactions.

Summary: In this study, non-toxic composite nanofibers were fabricated by incorporating controlled amounts of boron nitride (BN) nanosheets (5 %), titanium oxide (TiO2) nanofibers, and halloysite nanotubes (HNT). The aim was to obtain an efficient catalyst for acetaminophen (ACT) degradation. The results showed that the BN/TiO2/HNT nanocomposite degraded over 98% of acetaminophen after 3 hours of visible light irradiation. The composite also maintained its degradation rate after five cycles and OH center dot-, O2 center dot-, and h+ were found to play major roles in the degradation process.

Summary: Fe3O4/ZnO nanocomposites were synthesized by the solid-state method using different ratios of zinc oxide and iron oxide. The nanocomposites exhibited significant Raman shifts and quenching in PL intensity due to the strong incorporation of ZnO with Fe3O4. The photocatalytic activities of the nanocomposites showed enhanced degradation efficiency of methylene blue under visible light, with a stable catalytic performance over multiple cycles.

Summary: In this study, novel nanocomposites of activated carbon/graphene oxide/tin oxide (AC/GO/SnO2) and activated carbon/graphene oxide/titanium-zinc acetate dehydrate (AC/GO/TiO2-Zn) were synthesized using hydrothermal method. The structural phase change, morphology, and microstructural arrangement in the nanocomposites were characterized using various techniques. Symmetry supercapacitor electrode devices were fabricated using the nanocomposites and their electrochemical properties were evaluated. The AC/GO/TiO2-Zn electrode demonstrated high specific capacity and cycle stability, indicating its suitability for supercapacitor applications.

Summary: In this study, hierarchical and hollow microspheres assembly of one-dimensional zinc-trimesic acid (Zn-BTC) MOF nanospikes were successfully synthesized using a single step solvothermal synthesis method. The formed Zn-BTC hierarchical and hollow microspheres were annealed to form ZnO/C hierarchical nanocomposite microspheres. These hierarchical nanocomposite microspheres exhibited enhanced photocatalytic activities for water remediation. The improved photocatalytic performance was attributed to the synergistic effect between the carbon matrix and well-dispersed ZnO quantum dots.

Summary: This study proposes a simple and feasible method for preparing titanium oxide photocatalysts with reduced band gap, high electrical conductivity, and good chemical and structural stability. By co-doping N and F and oxygen deficiency, the visible light absorption and photocatalytic activity can be significantly enhanced. This work provides an important method for designing and fabricating high-performance titanium oxide photocatalysts.

Summary: A large number of emerging contaminants, such as pharmaceuticals, are difficult to remove from water bodies using conventional treatment methods, leading to serious environmental issues. Semiconductor-based photocatalysis has emerged as an exciting solution for the degradation of these pollutants. However, the diverse chemical composition of pharmaceutical pollutants poses challenges in selecting suitable photocatalysts for efficient and broad removal, necessitating systematic studies on the physicochemical properties of photocatalysts and pollutants.

Summary: Water, the primary source of life, is often contaminated with organic and inorganic impurities, with organic dyes from industries being a major contributor to pollution. This study focused on the photocatalytic degradation of malachite green dye using zinc oxide nanoparticles and beta-cyclodextrin. Characterization of the nanomaterials was done through various techniques, and optimization of parameters like dye concentration, pH, and catalyst amount was conducted. The study found that the ZnO-beta-CD composite showed better photocatalytic activity compared to ZnO NPs, with a plausible mechanism for the degradation process proposed.
