Construction of in situ self-assembled FeWO₄/g-C₃N₄ nanosheet heterostructured Z-scheme photocatalysts for enhanced photocatalytic degradation of rhodamine B and tetracycline

Abstract

Constructing a direct Z-scheme photocatalyst of in situ self-assembled FeWO4/g-C3N4 nanosheet composite provides a sustainable pathway for organic pollutant degradation.

Ag decorated G‐C3N4/black titanium oxides composite for the destruction of environmental pollutant under solar irradiation

“…In accordance with the previous studies, this work also demonstrates increased photocatalysis for the complete photodegradation of RhB of the ternary composite with reduced black titanium oxides and Ag nanoparticles. Recent studies on the removal of RhB by the g‐C 3 N 4 ‐based photocatalyst showed similar types of photodegradation curves to the one reported here . Dadigala et al reported an optimized system containing a large amount of metal oxide component (10 % FeWO 4 /g‐C 3 N 4 ) that demonstrated an almost complete removal of RhB after ∼90 min of sunlight irradiation.…”

Yan et al reported a ternary photocatalyst system, Ag 3 PO 4 /GO/g‐C 3 N 4 , with a ∼95 % photodegradation of RhB after 50 min of visible‐light irradiation.…”

“…In our recent study, we reported the facile synthesis of g‐C 3 N 4 composites with Cu(I)‐based oxides for an enhanced photodegradation of RhB . A novel Z‐scheme of FeWO 4 /g‐C 3 N 4 was constructed by an in‐situ self‐assembly solvothermal approach that demonstrated the enhanced photodegradation of RhB under natural sunlight irradiation . The enhanced visible‐driven photodegradation of RhB over a ternary system, Ag 3 PO 4 /GO/g‐C 3 N 4 , was reported by Yan et al…”

Sunlight-assisted degradation of textile pollutants and phytotoxicity evaluation using mesoporous ZnO/g-C3N4catalyst

“…It was hence concluded that the textile effluent did not undergo any self-degradation. 46 The efficiency of g-C 3 N 4 , ZnO, and various ratios of ZnO/g-C 3 N 4 for textile wastewater treatment was then studied as a batch experiment in a 200 mL beaker containing 100 mL wastewater. The experiment was conducted separately for each catalyst without dilution of textile effluent.…”

A magnetically separable and recyclable g-C3N4/Fe3O4/porous ruthenium nanocatalyst for the photocatalytic degradation of water-soluble aromatic amines and azo dyes

“…38 Several modications, such as chemical doping with metal and non-metals, have been attempted to improve the photocatalytic activity of pure g-C 3 N 4 . [39][40][41][42][43][44][45][46][47][48][49] On the other hand, ruthenium nanoparticles are known for their potential in various catalysis-based applications. [50][51][52][53][54][55][56] Because of their quantized nature, ruthenium nanoparticles can enhance the efficiency of photo-excited electron-hole pair separation and thereby, increase the photocatalytic activity of nanocomposites comprising g-C 3 N 4 .…”
