Summary: A unique BiOCl double-shelled hollow microsphere structure with adjustable shell thickness was fabricated for the first time through a template-free one-pot solvothermal method. The photocatalyst exhibited excellent carbamazepine degradation efficiency under simulated solar irradiation, outperforming conventional BiOCl solid microspheres. The presence of nanosheet subunits and porous structures shortened the diffusion length of charge carriers, facilitating the separation and transfer of photogenerated species. The double-shelled hollow structure also achieved higher light utilization.

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.
