石墨烯光催化降解甲醛复合材料性能的研究进展

Research Progress of Graphene Synergistic Flame Retardant Polymer Composites

甲醛为室内常见的挥发性有机污染物之一,长期吸入会对人体造成不可逆的伤害。光催化降解甲醛是当今净化甲醛的研究热点与市场首选,但单一的光催化剂仍存在一些问题。石墨烯是一种新型二维碳材料,具有大比表面积、高导电率、强化学稳定性等特点,在光催化技术领域展示出良好的应用前景。本文详细介绍了石墨烯光催化降解甲醛复合材料的机理,总结了石墨烯/光催化降解甲醛二元与三元复合材料相关性能的研究进展,分析了现存问题,对未来的发展方向进行了展望。

Formaldehyde was one of the common indoor volatile organic pollutants,and long-term inhalation would seriously endanger human health.Photocatalytic degradation of formaldehyde system was the research hotspot and market first choice for formaldehyde purification,but there were still some problems with single photocatalyst.Graphene was a new type of two dimensional carbon material,it had high specific surface area,high electrical conductivity,strong chemical stability,etc.,and showed excellent application prospects in the field of photocatalysis technology.In this paper,the mechanism of graphene photocatalytic degradation of formaldehyde composites was introduced in detail,the research progress of graphene/photocatalytic degradation of formaldehyde binary and ternary composites was summarized,the existing problems were analyzed,the future development direction was prospected.
