Accelerating carrier separation to boost the photocatalytic CO reduction performance of ternary heterojunction Ag-TiCT/ZnO catalysts.

Developing low-cost and efficient photocatalyst/co-catalyst systems that promote CO reduction remains a challenge. In this work, Ag-TiCT composites were made using a self-reduction technique, and unique Ag-TiCT/ZnO ternary heterojunction structure photocatalysts were created using an electrostatic self-assembly process. The photocatalyst's close-contact heterogeneous interface increases photogenerated carrier migration efficiency.

Interfacial construction of P25/BiWO composites for selective CO photoreduction to CO in gas-solid reactions.

Photocatalysis provides an attractive approach to convert CO into valuable fuels, which relies on a well-designed photocatalyst with good selectivity and high CO reduction ability. Herein, a series of P25/BiWO nanocomposites were synthesized by a simple one-step hydrothermal method. The formation of a heterojunction between BiWO, which absorbs visible light, and P25, which absorbs ultraviolet light, expands the utilization of sunlight by the catalysts, and consequently, leads to a remarkably enhanced CO selective photoreduction to CO.

fabrication of porous biochar reinforced WO nanocomposite for methylene blue photodegradation.

In this paper, a novel cow dung based activated carbon (CDAC) was successfully modified by WO nanowires as a photocatalyst using KOH activation and a hydrothermal method. The activity of photocatalytic degradation of methylene blue (MB) under full-spectrum light illumination shows great improvement, and the degradation rate of MB could reach 98% after 240 min (67% for WO), with a final degradation rate of 98%. The porous structure with specific surface area of CDAC (∼479 m g) increases the adsorption of WO reactants and also raises the concentration of reactants in the photocatalytic region.

Chemically activated core-shell structured IF-WS@C nanoparticles enhance sugarcane-based carbon/epoxy nanocomposites.

Ternary composites have demonstrated better capability than binary composites in enhancing the mechanical properties of the modified epoxy resins and are, therefore, currently under intensive investigation. Herein, we report a novel ternary nanocomposite prepared by filling a binary BPF (bisphenol F epoxy resin)/SCPs (sugarcane-based carbon powders) matrix with C-coated inorganic fullerene-like tungsten disulfide (IF-WS@C) nanoparticles, and the analysis of its interface synergetic effect using XPS/FTIR. This activated nano-carbon core-shell structure filler is considered an ideal nanofiller and shows the excellent mechanical performance of the ternary composites.
