Improvement of synergistic effect photocatalytic performance for efficient removal of tetracycline by the construction of double sulfide heterojunction

Precise Defect Engineering with Ultrathin Porous Frameworks on g-C3N4 for Synergetic Boosted Photocatalytic Hydrogen Evolution

“…Moreover, after removing N sites in the C–NC group, the unsaturated carbon sites aroused from N vacancies are beneficial to adsorb more reactant molecules and then activate them by the accumulated electrons. In particular, N vacancies have been explored to increase the adsorption of water molecules, thereby facilitating hydrogen evolution . Meanwhile, during this hydrogen evolution system, the N defects with g-C 3 N 4 could enhance water adsorption and further prompt water molecules to generate H 2 via the accepted electrons.…”

“…In particular, N vacancies have been explored to increase the adsorption of water molecules, thereby facilitating hydrogen evolution. 57 Meanwhile, during this hydrogen evolution system, the N defects with g-C 3 N 4 could enhance water adsorption and further prompt water molecules to generate H 2 via the accepted electrons. However, the existence of numerous defects could be attributed to the narrowed bandgap energy and the decreased redox activity over photoinduced electron−hole pairs.…”

Strengthened H2O adsorption and photogenerated carrier separation: surface C-coupled hydroxylation of g-C3N4 photocatalysts for efficient H2 production

“…11 During the photocatalytic process, practical application is limited by the restricted separation and transfer of photocatalytic carriers. 12 Therefore, fabricating novel functional and earth-rich semiconductors to enhance the photo-conversion and efficient separation of charges is vital for water splitting for H 2 production.…”
