Sacrificial agent-free, solar-driven photocatalytic oxygen reduction holds promise for
hydrogen peroxide production. However, the rapid recombination of electron–hole pairs in …

Carbon dioxide (CO2) capture and conversion to value-added chemicals such as
hydrocarbons or other energetic fuels is a potential alternate to carbon capture and …

Generally, thin-film composite (TFC) membranes prepared using piperazine (PIP) and
trimesoyl chloride (TMC) exhibit good Na 2 SO 4 rejection, but their MgCl 2 rejection is not …

In general, the addition of co-catalysts can effectively solve the problem of severe

Abstract Two‐dimensional (2D) covalent organic frameworks (COFs) have a multilayer
skeleton with a periodic π‐conjugated molecular array, which can facilitate charge carrier …

Donor‒acceptor covalent organic frameworks (D‒A COFs) have been regarded as
promising materials for photocatalytic water splitting because of their tunable band gaps …

The selective tandem one-pot synthesis of secondary amines via nitrobenzene and
benzaldehyde coupling–hydrogenation is challenging due to side reactions. Herein, a …
