Unlike inorganic crystals, metal-organic frameworks do not have a well-developed nanostructure library, and establishing their appropriately diverse complex architectures remains major challenge. Here, we demonstrate general route to control framework structure by solvent-assisted ligand exchange approach. Thirteen different types of structures been prepared successfully. To proof concept application, used the obtained materials as precursors for synthesizing nanoporous carbons investigated...
Abstract Dyes and antibiotics as typical persistent organic pollutants (POPs) are widely present in the environment, but can hardly be removed completely by traditional water treatment methods. Here, we designed Bi 4 O 5 Br 2 /g‐C 3 N composite nanosheets for efficient photocatalytic removal of POPs water.

Abstract Abstract:Catalyst surface dynamics drive the generation of active species for electrocatalytic reactions. Yet, understanding dominant site formation and reaction mechanisms is limited. In this study, we thoroughly investigate dynamic reconstruction two‐dimensional defective Bi nanosheets from exfoliated 2 Se 3 under electrochemical CO nitrate (NO − ) reduction conditions. The ultrathin obtained by NaBH 4 ‐assisted cryo‐mediated liquid‐phase exfoliation are more easily reduced...
