Summary: A catalytic membrane nanoreactor (CMNR) with Cu-Ag bimetallic catalysts immobilized in membrane pores was successfully fabricated via flowing synthesis and replacement reaction. The Cu core acts as an electron-deficient site to activate the -NO2 group for p-NP, while the Ag shell enhances active H spilling to the Cu surface for hydrogenation. The highest reaction rate constant of 1071 min(-1) was achieved for CMNR immobilized with Cu-Ag-2 due to suitable adsorption activation behavior and best hydrogen spillover behavior.

Summary: Combining morphology modification with heterojunction is an effective approach to enhance the photocatalytic activity of TiO2-based photocatalysts for wastewater treatment. In this study, a novel flower-like TiO2/Bi2O3 (FTB) photocatalyst was developed by depositing Bi2O3 nanoparticles on the surface of flower-like TiO2 (FT). The successful formation of p-n heterojunction between flower-like TiO2 and Bi2O3 was confirmed, which facilitates efficient charge separation. Due to the narrow bandgap of Bi2O3 and the unique flower-like microstructure, FTB exhibits a photocurrent 1.67 times higher than that of FT, resulting in a higher photo-degradation rate (92.7%) of levofloxacin compared to FT photocatalyst (approximately 80%). Moreover, FTB demonstrates excellent anti-interference capability towards environmental factors and good cyclability. This work provides new insights into the development of TiO2-based photocatalysts with advanced performance for antibiotic removal.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
