Abstract

Photocatalysis is an environmentally friendly approach and a propitious avenue for addressing water contamination including toxic chemicals, radioactive materials, and nitrate fertilizer. In the past few years, urbanization and industrialization have affected the water quality, causing various environmental hazards. Inland water ecosystems such as lakes, rivers and wetland not only play a vital role in maintaining biodiversity but also provide important sources of GHGs emissions. Despite their significance, the emission from inland water is poorly quantified. This review systematically reveals the sources of carbon and nitrogen emissions, the efficiency and mechanisms of various photocatalysts in degrading a range of organic pollutants, highlighting their potential to reduce environmental toxins significantly. The state-of-the-art and innovative remediation strategies targeting carbon emissions and N2 fixation have been thoroughly discussed. By consolidating photocatalytic processes with carbon sequestration and N2 fixation, the review develops a holistic approach to alleviating water quality and mitigating climate change impacts. Finally, the findings concluded with the role of advanced photocatalytic materials and proffering perspectives in promoting sustainable environmental management and ecological health in inland aquatic systems.
内陆水体有机污染物的光催化转化及碳排放固氮修复策略
光催化是一种环境友好的方法,是解决包括有毒化学物质、放射性物质和硝酸盐肥料在内的水污染的有利途径。在过去的几年里,城市化和工业化已经影响了水质,造成了各种环境危害。湖泊、河流和湿地等内陆水域生态系统不仅在维持生物多样性方面发挥着至关重要的作用,也是温室气体排放的重要来源。尽管它们意义重大,但内陆水域的排放却难以量化。本文系统地揭示了碳和氮排放的来源,各种光催化剂降解一系列有机污染物的效率和机制,强调了它们在显著减少环境毒素方面的潜力。深入讨论了针对碳排放和氮固定的最新和创新的修复策略。通过将光催化过程与固碳和固氮结合起来,本文提出了一种改善水质和减轻气候变化影响的整体方法。最后,总结了先进光催化材料在促进内陆水生系统可持续环境管理和生态健康方面的作用,并提出了展望。
