Article Abstract
We report here a BiWO/TiCT@Ag (BT@Ag) photothermal photocatalyst for efficient CO reduction with tunable CH selectivity. Incorporation of TiCT MXene creates well-defined heterointerfaces between BiWO and TiCT and converts thermal energy upon light illumination via photothermal effect, which contributes to a mitigation of the recombination of photo-induced charge carries for a high electron mobility. Density functional theory calculations substantiate that TiCT functions as the adsorption site and active center where the transferred electrons are effectively involved in CO reduction for enhanced CH selectivity. Moreover, the in situ deposited Ag nanoparticles demonstrate an exceptional surface plasmon resonance effect, giving rise to additional hot electrons that further benefits the CH generation.

Metal-organic frameworks (MOFs) are distinguished by their structural diversity, tunable electronic properties, and exceptional performance in various applications. Notably, the electron-donating ability of ligands significantly enhances the ligand-to-metal charge transfer (LMCT) processes within these frameworks, thereby promoting efficient charge migration. Herein, we developed two electron-rich macrocyclic ligands derived from phenothiazine- and phenoxazine-functionalized calix[3]arenes, alongside their corresponding cobalt-coordinated MOFs.

Airborne pathogens and pollution control typically necessitate multiple membranes, each specializing in efficient aerosol filtration, moisture regulation, or antimicrobial protection. Integrating all these functions into a single membrane is highly advantageous but remains inherently challenging due to material incompatibility and inevitable performance trade-offs. Here, we present a photoactive Janus nanofibrous membrane for highly efficient air purification, engineered via sequential electrospinning.

Polyesters, with their tunable chemical structures and environmental sustainability, have drawn growing attention as solid polymer electrolytes for next-generation solid-state lithium metal batteries (SSLMBs). Through a comprehensive experimental and theoretical study involving the systematic variation of carbon chain lengths in the flexible (diol) and coordinating (diacid) segments, along with selective fluorination at distinct positions along the polymer backbone, 18 types of polyester are fabricated and demonstrate that fluorination at the coordinating segment significantly enhances ionic conductivity by suppressing crystallinity. In contrast, fluorination at the flexible segment reduces ionic migration barriers by providing more homogeneous coordinating sites, thereby improving the lithium-ion transference number, despite increasing chain rigidity and a reduction in overall ionic conductivity.
