Novel intramolecular-tailored g-C₃N₄ with accelerated charge delivery for photocatalytic tetracycline degradation and hydrogen production: experimental studies and theoretical analyses

Abstract

The precise intramolecular-tailored strategy is deemed to have abundant potential to promote the activity of metal-free photocatalysts yet remains a daunting task. In this work, we report a simple one-step...

Proceeding of catalytic water splitting on Cu/Ce@g-C3N4 photocatalysts: an exceptional approach for sunlight-driven hydrogen generation

“…The strong vibrations observed at 810 and 870 cm −1 were ascribed to monomers of s -triazine that is characteristic of the g-C 3 N 4 structure. 42 The aromatic C–N stretching was depicted at 1243, 1326, 1409, and 1461 cm −1 , while the CN stretching was found at 1560 and 1642 cm −1 . The broad vibration at 3070 cm −1 was assigned to the O–H bond of absorbed H 2 O.…”

Building internal electric fields in porous ionic polymers for fast photocatalytic degradation of tetracycline hydrochloride

“…3–5 Great efforts have been devoted to tailor the photocatalysts to enhance the solar energy conversion efficiency. 6–8 However, the intrinsically strong propensity of charge/carrier recombination results in difficulties for charge-induced degradation of antibiotic contamination. 9–12 Currently, the surface engineering approaches to build the internal electric field (IEF), including heterojunctions, 13,14 phase junctions, 15–18 facet junctions, 19,20 co-catalyst loading 21 have been developed to spatially separate photogenerated hole–electron (h + –e − ) pairs, thereby enhancing the photocatalytic performance.…”
