Graphene was prepared via microwave assisted intercalation-exfoliation of graphite by using ammonia as intercalation agent. The effects of ammonia on graphene preparation and its intercalation mechanism were investigated. It was found that ammonia can greatly improve the exfoliation effect of graphene in the way of entering into the interlayer between graphite and forming C˭N bond. The quality of...
MXene, a new family of 2D transition metal carbides and carbonitrides, has been proved to possess excellent electrical conductivity and hydrophilicity. In this work, a single-step method to produce the larger interplanar spacing 2D MXene Ti3C2 by etching Ti3AlC2 with NH4HF2 was demonstrated, and the optimal reaction conditions between Ti3AlC2 and NH4HF2 were systematically researched. The morphology...
