Effective removal of hazardous organic contaminant using integrated photocatalytic adsorbents: Ternary zinc oxide/zeolite-coal fly ash/reduced graphene oxide nanocomposites

Fabrication of 1-octane sulphonic acid modified nanoporous graphene with tuned hydrophilicity for decontamination of industrial wastewater from organic and inorganic contaminants

“…Recently, Chatchai Rodwihok et al reported ternary zinc oxide/zeolite-coal fly ash/reduced graphene oxide (ZnO/Z/rGO) nanocomposites as photocatalytic adsorbent for organic contaminants and performed adsorption experiments using methylene blue. 84 Ferrihydrite-graphene oxide foams were also reported for the removal arsenic III from aqueous environment. The foams were able to remove 99% As( iii ).…”

Enhancing Removal of Acid Orange II by Heterogeneous Catalytic Ozonation Using ZnO Nanoparticles-Modified Fly Ash Composite

“…Due to its abundance, cost-effective, highly-available and environmental friendliness [28,29], y ash (FA) generated from coal power plants was employed as a subtrate to immobilize ZnO nanoparticles (NPs) via incipient wetness impregnation method, making ZnO nanoparticles-modi ed y ash (ZOFA) composite. Chatchai Rodwihok and co-colleagues prepared ternary zinc oxide/zeolite-coal y ash/reduced graphene oxide nanocomposites to effectively adsorb methylene blue (MB), and it was reported that the introduction of ZnO NPs would enhance the catalytic activity of the whole composite [30]. Therefore, the combination of ZnO NPs and FA to form ZOFA composite would be a promising material for catalytic ozonation.…”

Synthesis, characterization, and application of a zinc oxide–pyrrole–thiophene nanocomposite as an efficient adsorbent for the removal of tetracycline

“…[22][23][24][25][26] However, due to the absence of a large number of functional groups, the adsorption capacity of metal oxides is relatively low. To improve the adsorption capacity of such materials, these are synergistically associated with different crosslinkers, such as polymers, 27,28 zeolites, 29,30 molecular organic frameworks (MOFs), 31 covalent organic frameworks (COFs), clays, 32 and activated carbon. 33,34 Conducting polymer-based nanocomposites have attracted significant interest in recent years for their utilization in wastewater treatment.…”
