Recent progress in g-C3N4, TiO2 and ZnO based photocatalysts for dye degradation: Strategies to improve photocatalytic activity

Heterojunction photocatalysts for degradation of the tetracycline antibiotic: a review

“…Wang et al ( 2018a ) built a visible-light-driven BiOBr/Bi 2 SiO 5 heterojunction to enhance the elimination of tetracycline in an aqueous solution. Although several articles have reviewed the development of heterojunction architectures and their application in the purification of different environmental pollutants (Li and Li 2020 ; Low et al 2017 ; Nemiwal et al 2021 ; Wang et al 2014 ; Yu et al 2014a ), none has comprehensively summarized and emphasized on tetracycline photodegradation.…”

Graphitic Carbon Nitride as a New Sustainable Photocatalyst for Textile Functionalization

“…Various modification strategies have been employed in g-C 3 N 4 materials to improve the photocatalytic efficiency, which is inhibited by the high rate of e − –h + recombination process and low charge mobility, the inability to absorb visible light below 460 nm, low surface area, and limited interfacial interactions [ 36 ]. Some of these strategies include heterojunction fabrication [ 17 , 22 , 37 , 38 ], metal doping [ 19 ], non-metal doping [ 39 ], and structural defect engineering [ 22 , 34 ].…”

Facile synthesis of nitrogen-defective g-C3N4 for superior photocatalytic degradation of rhodamine B

“…16,18 Following research found that the photocatalytic activity can be improved through modifying g-C 3 N 4 's morphology, [19][20][21] element doping, [22][23][24] and semiconductor compounding, [25][26][27] advancing the applications of g-C 3 N 4 in photocatalysis. 28,29 In these modication methods, the morphology control is a simple and effective way to adjust the surface structure to improve photocatalytic activity without introducing additional unit components during the synthesis process of the modied g-C 3 N 4 . 30 In this work, a porous g-C 3 N 4 photocatalyst with nitrogen defects was developed for the photodegradation of RhB organic dyes (Scheme 1).…”
