Abstract

Hexavalent chromium (Cr(vi)) is a prominent carcinogen. In environmental engineering, the elimination of hexavalent chromium from aqueous media is a noteworthy field of study. In this regard, nanoparticle science and technology have contributed significantly to the photocatalytic reduction of Cr(vi). In this review, a methodical search was undertaken to discover the most recent advancements in the field of photocatalytic reduction of Cr(vi) utilizing g-CN and composites derived from it. This paper deals with the advancements and applications of g-CN and its composites in the Cr(vi) remediation of water-borne pollutants. Different intriguing systems, suggested by various researcher groups, have been discussed. Different characterization techniques often conducted on photocatalysts based on g-CN have also been highlighted so as to gain an understanding of the Cr(vi) removal process. Lastly, the future scope of the g-CN-derived photocatalysts, present challenges, and the viability of employing these photocatalysts in an extensive treatment plant have been discussed.

摘要

六价铬（Cr(vi)）是一种著名的致癌物。在环境工程领域，从水介质中去除六价铬是一个值得关注的研究方向。在这方面，纳米颗粒科学与技术对六价铬的光催化还原起到了重要作用。在本综述中，我们进行了系统的检索，以探寻利用g-CN及其衍生复合材料在六价铬光催化还原领域的最新进展。本文论述了g-CN及其复合材料在去除水中污染物中六价铬方面的进展与应用。文中讨论了不同研究团队提出的各种有趣的体系。同时还重点介绍了常用于基于g-CN的光催化剂的不同表征技术，以便了解六价铬的去除过程。最后，探讨了g-CN衍生光催化剂的未来发展前景、当前面临的挑战以及在大型处理厂中使用这些光催化剂的可行性。
