Rationally designed tetra (4-carboxyphenyl) porphyrin/graphene quantum dots/bismuth molybdate Z-scheme heterojunction for tetracycline degradation and Cr(VI) reduction: Performance, mechanism, intermediate toxicity appraisement

Metal–organic framework‐based heterojunction photocatalysts for organic pollutant degradation: design, construction, and performances

“…The main disadvantage of type-II heterostructures is that the oxidation and reduction abilities of the transferred e − and h + decrease because the electrons migrate to the CB of a semiconductor with lower reduction potential and holes accumulate on the VB of a material with lower oxidation potential. Thus, the development of new heterojunctions, e.g., Z-scheme, 158,159 may solve this drawback.…”

Polypyrrole and a polypyrrole/nickel oxide composite – single-walled carbon nanotube enhanced photocatalytic activity under visible light

“…2,4 Designing visible light active photocatalysts having excellent charge transfer and charge separation efficiency with maximum utilization of sunlight irradiation is a key challenge today. Out of several strategies, compositing [5][6][7][8][9] and heterojunction [10][11][12][13][14][15][16] formation are used for enhanced organic pollutant degradation.…”

Construction of a Bi2MoO6/CoOx/Au system with a dual-channel charge transfer path for enhanced tetracycline degradation

“…[1][2][3][4][5] Fortunately, photocatalytic technology, a type of advanced oxidation process, offers a promising avenue for the elimination of residual TC in wastewater due to high efficiency, cost-effectiveness, and environmental friendliness. [6][7][8][9][10] Bismuth molybdate, which possesses a distinctive layered structure and suitable bandgap, has been reported as a promising two-dimensional (2D) photocatalyst for antibiotic degradation under visible light. [11][12][13][14] However, the photocatalytic properties of pristine BMO in practical application are not as good as what is expected.…”
