Recent progress in emerging materials and hybrid nanocomposites for peroxymonosulfate and peroxydisulfate activation towards solar light-driven photocatalytic degradation of emerging pollutants

Defect Engineering in Nanocatalysts: From Design and Synthesis to Applications

“…[ 187 ] Therefore, to explore novel substances for speedy photocatalysis, researchers must investigate in detail the role of the introduced defects in the photoactivation of the catalysts. [ 188 ] For instance, Zn‐doped gallium oxynitride nanowires‐based photocatalysts exhibited superior visible light photocatalysis toward Rhodamine B (RhB). [ 48 ] Nearly 30% quantum efficiency was attained, which was 13‐fold higher compared to materials without lattice defects, and complete decolonization was observed in 100 min exposure to light through a pseudo‐first‐order reaction.…”

Degradation of Pesticides Using Semiconducting and Tetrapyrrolic Macrocyclic Photocatalysts—A Concise Review

“…AOPs (Figure 1) are based on the generation of highly reactive and rather unselective species, such as hydroxyl (HO • ) or sulfate SO4 •− radicals, or singlet oxygen ( 1 O2) [19][20][21]. In this review, we focus solely on photochemical processes, particularly highlighting the use of photosensitizing catalysts in the degradation of pesticides.…”

Charge transfer in TiO2-based photocatalysis: fundamental mechanisms to material strategies

“…1–4 On the one hand, the excessive use of fossil fuels has resulted in the rapid depletion of energy resources; on the other hand, the burning of these hydrocarbon fuels has contributed a huge amount of carbon dioxide to the atmosphere, which is responsible for global warming and poses a threat to life on Earth. 5–7 Furthermore, the establishment of large manufacturing industries, including cosmetic industry, 8–10 petrochemical industry, 11–13 plastic industry, and leather industry, as well as varnishes, medicines, 14,15 antibiotics, 16 insecticides, herbicides, dyes, 17–19 clothes, perfumes, explosives, sound systems, batteries, slaughter houses, and heavy metals, 20–22 for the purpose of making human life comfortable and relaxed have disturbed normal aquatic and terrestrial life in the sense that these industries have added their own contribution towards environmental pollution especially drinking water and atmospheric pollution by disposing of their hazardous residues and used-water directly into water streams. 23–28 Therefore, new technologies are urgently needed to address these problems efficiently.…”
