摘要
金纳米作为贵金属纳米材料,在生物医学、传感、催化等领域都有广泛应用。尤其在催化领域,金纳米材料既可以催化偶氮染料、硝基化合物等水污染物,也可以催化CO、甲醛等空气污染物,是良好的环境污染物的催化剂。但是金纳米材料制作成本较高且溶液稳定性较差,需要与其他材料复合提高其催化应用性。因此,利用金纳米与其他材料复合形成新的金纳米复合材料用于催化环境污染物成为研究热点。
As a precious metal nanomaterial,gold nanoparticles are widely used in biomedicine,sensing,catalysis and other fields.Especially in the field of catalysis,gold nanomaterials can catalyze water pollutants such as azo dyes and nitro compounds,as well as air pollutants such as CO and formaldehyde,and are good catalysts for environmental pollutants.However,the production cost of gold nanomaterials is high and the solution stability is poor,so it needs to be compounded with other materials to improve its catalytic applicability.Therefore,the use of gold nanocomposites with other materials to form new gold nanocomposites for catalyzing environmental pollutants has become a research hotspot.
