High population growth, industrialization, precipitous urban settlement, and poor government policies in some circles have increased resource consumption various environmental activities that promote water pollution. Diverse materials such as nanomaterials, quantum dots, carbonaceous materials, quaternary-metallic oxides been very successful removing benign pollutants from contaminated bodies. Lately, transition metal (TMOs) chalcogenides (TMCs), their composites attracted favorable research interest applications due to flexible elemental composition, manipulatable bandgaps, earth abundance, optoelectrical properties, visible light activity, catalytic stability. This review explores the of binary, ternary, quaternary, heterostructure TMOs TMCs for a broad range biological, organic, inorganic wastewater treatment. The popular treatment strategies explored include photocatalysis, adsorption, antimicrobial, persulfate/peroxymonosulfate activation, Fenton-like process. mechanisms catalysis these processes were briefly highlighted prospects use discussed.

ACS ES&T Engineering, Journal Year: 2023, Volume and Issue: 4(1), P. 19 - 46

Published: Aug. 14, 2023

Persulfate based advanced oxidation processes (PS-AOPs) have been regarded as a mainstream degradation technology of organic compounds due to their high efficiency in wastewater treatment. In particular, peroxymonosulfate (PMS) has unique structure and chemical properties, which can be efficiently activated by Co-based catalysts produce active species with potential. These usually determine the subsequent an efficient process, while intrinsic reaction mechanism behind this complex process remains unclear therefore impedes continual development scientific community. Recently, density functional theory (DFT) calculations emerged powerful means identify electronic properties distinguish energy changes PMS activation system. With assistance quantum calculation, increasing investigations conducted focusing on explaining phenomenon that occurred experiments. However, these mainly contributed part sometimes even differ from each other, lacking comprehensive summary DFT calculation results. review, we introduce main uses catalytic PMS, provide recent application examples heterogeneous different structures, then discuss detail. Finally, research results method field are summarized, future focus challenges put forward, is conducive guiding practical design further PS-AOPs creating value products.

Adsorption–Activation Bifunctional Center of Al/Co‐Base Catalyst for Boosting 5‐Hydroxymethylfurfural Oxidation

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: 14(43)

Published: Aug. 2, 2024

Abstract Electrocatalytic conversion of biomass‐derived 5‐hydroxymethylfurfural (HMF) to value‐added 2,5‐furandicarboxylic acid (FDCA) is great significance in compensating for the rapid consumption fossil resources. However, it a challenge further improve performance HMF electrocatalytic oxidation (HMFOR) by synergistic kinetics (active sites) and thermodynamics (adsorption sites). In this work, Al(OH) 3 /Co(OH) 2 successfully fabricated as an efficient catalyst, its catalytic mechanism clarified. Extended X‐ray absorption fine structure (EXAFS) analysis demonstrate that electrochemically generated Co 3+ main site oxidation. The equilibrium adsorption capacity reach 57.0 mg g −1 , which effectively increase initial concentration substrate promoted reaction rate. combined results, based on 24 stable cycles FDCA yield retention rate 98.6% after 180 days, are highest ever achieved. Additionally, shown system can oxidize four other substrates. Therefore, work provides insight into hydroxide catalyst owes efficiency synergy between active sites.
