Zinc Chloride-Doped g-CN Microtubes for Enhanced Photocatalytic Degradation of Tetracycline Hydrochloride.

Morphology regulation and element doping are effective means to improving the photocatalytic performance of graphite-phase carbon nitride (g-CN). In this article, using melamine and zinc chloride as raw materials, a novel kind of Zn/Cl-doped hollow microtubular g-CN (Zn-HT-CN) by a hydrothermal method was developed. The structure and morphology of Zn-HT-CN and reference samples were characterized by X-ray diffraction patterns (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), etc.

CuO@Cu@NiAl-LDH with Cu/Cu Valence Synergy and Core-Shell Structure for Highly Selective Generation of CH.

Photocatalytic CO reduction to produce C products remains a challenge. Herein, CuO@Cu@NiAl-LDH composites with three-dimensional ordered core-shell structures were successfully prepared, and the effects of CuO with different exposed surfaces on CO photoreduction were investigated. The synergistic effect of zero-valent Cu and Cu as intermediate electron mediators retains more photogenerated electrons and the Z-scheme heterojunction formed between CuO and NiAl-LDH leads to the enhancement of C selectivity.

Bismuth-Metal and Carbon Quantum Dot Co-Doped NiAl-LDH Heterojunctions for Promoting the Photothermal Catalytic Reduction of CO.

The quest for sustainable photocatalytic CO reduction reactions (CRR) emphasizes the development of high-efficiency, economically viable, and durable photocatalysts. A novel approach involving the synthesis of Bi-CDs/LDH heterojunctions, incorporating plasma metals and carbon quantum dots via hydrothermal and co-precipitation methods, yields remarkable results. The optimized BCL-4 photocatalyst demonstrates exceptional performance, with CH and CH yields of 1.

Research progress on photocatalytic reduction of CO based on ferroelectric materials.

Transforming CO into renewable fuels or valuable carbon compounds could be a practical means to tackle the issues of global warming and energy crisis. Photocatalytic CO reduction is more energy-efficient and environmentally friendly, and offers a broader range of potential applications than other CO conversion techniques. Ferroelectric materials, which belong to a class of materials with switchable polarization, are attractive candidates as catalysts due to their distinctive and substantial impact on surface physical and chemical characteristics.
