Stainless steel (SS) is gaining momentum in DWDS, particularly in end-point distribution facilities such as secondary water storage tanks, pumps, and household water pipes due to its high chemical stability and robust mechanical strength. However, SS’s susceptibility to corrosion in given defect areas is of great concern, and there is a lack of fundamental insight on SS corrosion from an interdisciplinary perspective of materials science and environmental science. Herein, the SS corrosion in the DWDS environment is critically assessed, encompassing the basic science of SS corrosion occurrence, its cascading influence on water quality, and anticorrosion strategies. Electrochemical corrosion mechanisms of SS corrosion are specifically differentiated, particularly those initiated at given SS defects, including welding points, grain boundaries, and areas with tensile stress. It is shown that SS corrosion influences water quality by destroying the Cr-rich passive film and releasing Cr, Fe, and other heavy metals from the corrosion scale. The critical factors influencing SS corrosion are subsequently identified, namely, SS elemental composition, SS manufacturing process (e.g., heat-affected zone, stress concentration), and water condition in DWDS (e.g., chlorine, oxygen, sulfate, hydraulic shock, pH). Corresponding strategies are elucidated to facilitate the anticorrosion resistance of SS and improve the water quality, including SS alloying enhancement, SS dispersion strengthening, SS surface treatment/modification, and tuning water condition in DWDS. Overall, this review highlights the importance of controlling SS corrosion, which could provide guidance on the rational design and utilization of SS in DWDS to enhance the ultimate water quality of the end-users and the overall resilience of the DWDS.</p>","PeriodicalId":7008,"journal":{"name":"ACS ES&T engineering","volume":"5 6","pages":"1357–1372 1357–1372"},"PeriodicalIF":7.4,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144269613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a promising strategy, the catalytic oxidation of VOCs into harmless products such as H<sub>2</sub>O and CO<sub>2</sub> has been widely employed. Although many catalysts have been developed for VOC decomposition, the design and synthesis of functional catalysts toward multicomponent VOC purification in industrial exhaust gas under reality remains a great challenge. In the actual vent, the composition of multicomponent VOCs is complex and impurities such as NO<sub><i>x</i></sub>, SO<sub>2</sub>, and H<sub>2</sub>O are also present. Traditional catalysts often suffer from poor stability, deactivation by impurities, and inefficient oxidation of complex VOC mixtures in industrial settings. Addressing these challenges requires a deeper understanding of the fundamental mechanisms and advanced catalyst design strategies. Therefore, elucidating the mechanism of multicomponent VOC oxidation and revealing the influential behavior of impurities are urgently required to guide researchers on how to synthesize effective and stable catalysts proactively for multicomponent VOC purification under reality. Accordingly, this review systematically summarizes the recent advances in the engineering of highly active and durable catalysts for the oxidation of multicomponent VOCs. The experimental and theoretical studies revealing the mixing effects occurring in the catalytic oxidation process of multicomponent VOCs are also highlighted. Further development of and research on catalysts to be adopted in multipollutant controlling are proposed. This review can help researchers to better understand the catalytic elimination of multicomponent VOCs and provide a great foundation for future design and practical industrial application of VOC oxidation catalysts.</p>","PeriodicalId":7008,"journal":{"name":"ACS ES&T engineering","volume":"5 6","pages":"1316–1337 1316–1337"},"PeriodicalIF":7.4,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144269912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
