二维纳米材料MXene的制备方法及其光催化应用研究进展

Research progress on the preparation method of MXene 2D nanomaterial and its photocatalytic application

二维过渡金属碳化物/氮化物/碳氮化物(MXene)作为一种新发现的超薄二维纳米材料,因其良好的导电性和亲水性,被广泛应用于储能、催化、光电等领域。MAX相是包含70多种化合物的庞大家族,目前主要是利用化学蚀刻的手段通过选择性蚀刻掉前驱体MAX相中的A原子层而得到MXene。为了更好地了解MXene,综述了从MAX相到MXene的剥离方法及其在光催化领域的应用,以期为研究者提供思路和参考。

2 Dtransition metal carbide/nitride/carbonitride(MXene)as a newly discovered 2 \D ultra-thin nanomaterial is widely used in the fields of energy storage,catalysis and photoelectricity due to its good conductivity and hydrophilicity.MAX phase is a large family of more than 70 compounds.At present,MXene is mainly obtained by selectively etching A atomic layer out of precursor MAX phase by means of chemical etching.In order to better understand MXene well,the preparation method from MAX phase to MXene and its application in the photocatalysis were reviewed,hoping to provide ideas and references for researchers.
