Cu2O@Cu@NiAl-LDH with Cu0/Cu+ Valence Synergy and Core-Shell Structure for Highly Selective Generation of C2H6.

Photocatalytic CO2 reduction to produce C2 products remains a challenge. Herein, Cu2O@Cu@NiAl-LDH composites with three-dimensional ordered core-shell structures were successfully prepared, and the effects of Cu2O with different exposed surfaces on CO2 photoreduction were investigated. The synergistic effect of zero-valent Cu and Cu+ as intermediate electron mediators retains more photogenerated electrons.

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.
