Peptide-Based Gel in Environmental Remediation: Removal of Toxic Organic Dyes and Hazardous Pb2+ and Cd2+ Ions from Wastewater and Oil Spill Recovery

“…They are most commonly found in the by-products from the metallurgic industries, textile, printing, and other manufacturing sites which uses the techniques of chemical precipitation, flocculation, biotreatment and so on. [54][55][56][57] Highly toxic organic dyes and heavy metal ions such as Pb 2+ , Cd 2+ , Hg 2+ , Cr 6+ and uranium poses a great threat to the environment and human health, and many organic dyes are also toxic and carcinogenic in nature. Untreated dye effluent from industry pollutes water leading to serious hazards for aquatic life and mankind.…”

“…The toxicity of contaminated water is caused by heavy metals and organic dyes. They are most commonly found in the byproducts from the metallurgic industries and textile, printing, and other manufacturing sites that use the techniques of chemical precipitation, flocculation, bio-treatment, and so on. − Highly toxic organic dyes and heavy metal ions such as Pb 2+ , Cd 2+ , Hg 2+ , Cr 6+ , and uranium pose a great threat to the environment and human health, and many organic dyes are also toxic and carcinogenic in nature. Untreated dye effluents from industry pollute water, leading to serious hazards for aquatic life and mankind. − The presence of toxic dyes in water can be harmful to human beings and other living species even at low concentrations because these are generally nondegradable in nature.…”

Recent developments in metal-doped SBA-15 catalysts for heterogeneous catalysis and sustainable chemistry

“…The direct method facilitates the isomorphous substitution of heteroatoms in the mesoporous silica via co-condensation and is normally carried out in an acidic medium. However, recent developments suggest that it can be carried out at neutral conditions by using hydroxyl radical [32] . Furthermore, direct synthesis suggests a uniform distribution of functional groups on the SBA-15 material surface and structure, preserving the morphology of materials which is in accordance with the finding of Zhao et al [1] .…”

Microwave Hydrothermally Synthesized Metal–Organic Framework-5 Derived C-doped ZnO with Enhanced Photocatalytic Degradation of Rhodamine B

“…Environmental pollution becomes more serious, especially from the release of organic dyes. − Among the reported technologies for eliminating toxic organic dyestuffs, − photocatalytic degradation is a nonpoisonous and highly efficiency method, − which can decompose the organic pollutants into CO 2 and H 2 O. , Among the reported photocatalysts for photocatalytic degradation, including ZnO, g-C 3 N 4 -Bi 2 O 2 CO 3 , Beta-bismuth­(III) oxide nanopowders, WO 3 /g-C 3 N 4 , Ag/TiO 2 /rGO, Cu 2 O, ZnIn-layered double oxides, and Cu­(II) complex powder, ZnO is more promising to serve as a solar photocatalyst because of its thermal stability, easy synthesis, and photosensitivity . Meanwhile, the wide band gap (∼3.3 eV) of ZnO affects the visible light absorption, , and quick recombination of photoelectrons (e – ) and holes (h + ) also affects the formation of reactive radicals, which greatly limit its photocatalytic performance .…”
