The formation of interfacial electric fields using semiconductors/co-catalysts can effectively improve the carrier migration efficiency photocatalytic devices. Herein, an ultrathin 2D/2D/2D black phosphorus/MXene/MBene (denoted as BP/Ti3C2/MoB) ternary heterojunction with enhanced charge transfer is designed dual fields. formed by BP/Ti3C2 and Ti3C2/MoB accelerate photogenerated transfer, change position d-band center Ti atoms, lower energy level antibonding state, enhance adsorption effect H∗ active species, which ultimately leads to significant enhancement activity. results show that optimum visible-light-induced H2 evolution rate BP/Ti3C2/MoB 8,624 μmol g−1 h−1, has a very high factor (∼1,563%) compared pure BP. charge-transfer pathways mechanism are further elucidated some state-of-the-art spectroscopic characterizations theoretical calculations.

Bacterial cellulose (BC) membranes produced from biomass are emerging as an eco-friendly solution for water decontamination. The abundance of hydroxyl groups and the high surface-to-volume ratio this material allow integration diverse functional groups, providing potential targeted purification applications. Beyond their intriguing mechanical properties unique complex structure, bacterial biodegradable into sugar molecules can be processed with minimal handling using mild chemicals. Taken together, these features make them a compelling choice filtration in context environmental responsibility. In natural state, BC have limited wastewater treatment. One strategy enhancing functionality is to graft customized onto surface. Therefore, study aims impart multifunctionality membrane filtration. Hence novel precursor hard soft base functionalities consisting amines, carbonyls, amides, hydroxyls etc. designed grafted membranes, grown ensure surface uniformity membrane-to-membrane repeatability properties. structure synthesized precursors effective functionalization then validated through various structural characterization techniques. Changes morphology examined Scanning Electron Microscopy (SEM) Atomic Force (AFM). Both pristine modified undergo series tests assess capabilities under low-pressure regime efficiency removing representative cadmium chromium ions. exhibits superior performance permeability than pristine-BC. metal ions were rejected more 90% effluent. demonstrated flux recovery above maintaining its effectiveness even after five successive cleaning-filtration cycles.
