“…Zinc oxide (ZnO) has been of great interest because of its excellent physical properties, such as low cost, nontoxicity, high thermal stability, photosensitivity, advanced optical properties, and environmentally friendly features [5,6]. erefore, ZnO has been widely used in many fields, such as adsorption, paint, cosmetic, superconductor, and catalyst [7][8][9][10][11][12]. As an effective photocatalyst in the degradation of persistent organic compounds [13][14][15] and catalyst support [16,17], ZnO should have a sufficient structure area and morphology to allow the diffusion of active species and electron transfer [18].…”

In this study, the physical properties of ZnO were facile controlled by the synthesis method with the addition of capping and precipitation agents. As-prepared ZnO samples had different morphologies such as carnation flower-like ZnO (CF-ZnO), rose-flower-like ZnO (RF-ZnO), rod-like ZnO (R-ZnO), and nanoparticle ZnO (N-ZnO) and were characterized by SEM, XRD, N2 adsorption/desorption isotherms, FT-IR, and DR/UV-vis. All samples had a crystallite structure of hexagonal wurtzite type. The CF-ZnO and RF-ZnO samples had the hierarchical structure like a carnation flower and a beautiful rose, respectively. R-ZnO was composed of many hexagonal rods and few spherical particles, while N-ZnO microstructures were made up of nanoparticles with approximately 20–30 nm, exhibiting the largest surface area, pore volume, and pore width among as-prepared samples, and their crystal size and bandgap energy were 17.8 nm and 3.207 eV, respectively. The catalytic performances of ZnO samples were evaluated by degradation of Tartrazine (TA) and Caffeine (CAF) under low UV irradiation (15 W). N-ZnO showed a high photocatalytic activity compared to other samples. Besides, the reaction kinetics was investigated by the first-order kinetic model, and the catalytic performance of ZnO was evaluated through several organic pollutants.

“…In addition to TiO 2 -based photocatalysts, other catalysts with superior performance also have been reported for nonselective degradation and selective synthesis of plastic waste, including ZnO, − , ZrO 2 , RGO, , and some plant extracts. , For instance, Dai et al have constructed another innovative photocatalyst different from TiO 2 and other wide-gap catalysts, a biomass-derived 3D MoS 2 /RGO/cotton catalyst for PE degradation and solar-powered sustainable freshwater production . MoS 2 , as a distinguished and reliable photocatalyst, can readily generate various high ROS (e.g., •OH and •O 2 – ) than TiO 2 and to better mineralize the C–C bond of PE microplastics into CO 2 under sunlight irradiation.…”

Plastic waste pollution is becoming one of the most pressing environmental crises due to the large-scale production without satisfactory recycling schemes, especially with the outbreak of the COVID-19 pandemic in recent years. Upcycling of plastic waste into valuable chemicals powered by solar energy presents a substantially untapped opportunity to turn waste into treasure. In this review, the fundamental principles from plastic nonselective degradation to selective synthesis are first clarified. Then, we aim to outline the representative recent advances in photoredox-based catalytic plastic waste conversion. Particular emphasis is placed on the valorization of plastic waste regarding nonselective degradation versus selective synthesis. Finally, we present challenges and individual insights for further exploration of the plastic waste conversion domain. It is anticipated that this timely and critical review would provide an instructive direction and foresight on the selective conversion of plastics to valueadded chemical feedstocks, thus stimulating the development of a circular and sustainable plastic economy in the coming decades.

“…The usage of the paint type catalyst system has no problem in the dispersity, however, much more amount of the catalyst has been required. Surface modification of TiO 2 particle has been studied by some investigators [10,20]. They reported that the grafted nano-TiO 2 particles dispersed excellently in hydrophobic polymer.…”
