Description

technical field [0001] The invention belongs to the technical field of graphene, in particular to a graphene nano-layer for photoelectric degradation. Background technique [0002] Graphene is a two-dimensional crystal composed of carbon atoms with only one atomic thickness. In 2004, Andre Geim and Konstantin Novoselov, physicists at the University of Manchester, successfully separated graphene from graphite and confirmed that it can exist alone. Bell Prize in Physics. [0003] Before the discovery of boronene in late 2015, graphene was both the thinnest material and the strongest, with a breaking strength 200 times stronger than the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is currently the thinnest and strongest material in nature. If a piece of graphene with an area of ​​1 square meter is used to make a hammock, it can bear a cat weighing one kilogram with a weight of less than one milligram. [00...
