Summary: This study investigates the conversion of CO2 into high-value added chemicals driven by solar energy. The results show that the use of VO4-supported ultrathin NiMgV-layered double hydroxide as a catalyst achieves high efficiency and selectivity for the photocatalytic CO2 reduction reaction under visible light. The excellent performance of V/NiMgV-LDH can be attributed to its modulation of the band structure, promotion of electron-hole separation, and strong bonding with CO* and H* to facilitate hydrogenation and inhibit the formation of by-product H-2.

Summary: This study investigates the piezo-photocatalytic performance of different thicknesses of ZnAl layered double hydroxides (ZnAl-LDHs) in the degradation of CBZ pollutants. The results show that ultra-thin ZnAl-LDHs sheets exhibit higher efficiency and faster degradation rate, which can be attributed to their increased sensitivity to light irradiation and external stress. Additionally, the piezo-photocatalytic reaction of the ultra-thin ZnAl-LDHs is significantly enhanced compared to individual piezocatalysis and photocatalysis, due to the piezoelectric field's ability to boost the separation of electron-hole pairs and modulate band energy alignment.

Summary: This study proposes a solution to improve the electrochromic performance of tungsten oxide (WO3) by coating it with Prussian blue (PB) to form a core-shell structure. Experimental results show that the WO3/PB core-shell structure film exhibits higher electrochromic properties due to the formation of an electron pair donor-acceptor system and double electrochromic effect. This method provides a new direction for future electrochromic research.

Summary: In this study, nickel-based electrochromic films were prepared by a simple hydrothermal method and CdS quantum dots sensitization. The composite films with adsorbed CdS quantum dots showed a multifunctional non-electrochromic film with multiple color changes and a high optical modulation range. The presence of CdS improved the structural stability and charge storage capacity of the composite film, enhancing the electrochromic reaction. This research provides a reference for the development of NiO polychromatic electrochromic materials and expands the range of non-electrochromic materials from metal oxides to sulfides.
