Preparation of a graphene–phosphorene composite by pressure quenching and its ferromagnetism†
Abstract
A graphene–phosphorene composite was prepared by quenching the pressure in a LECO high-temperature and high-pressure hydrothermal reaction device. The results suggest that the graphene–phosphorene composite is a layered sandwich structure and shows strong ferromagnetism due to the P–C and P–O–C bonds formed between the graphene and phosphorene.
