Photocatalysis triggered CVD synthesis of graphene at low temperature†
Abstract
Conceiving the coupling strategy of photothermal catalysis, in which a CeO2 based photocatalyst facilitates the conversion of CH4 into hydrocarbon species with light irradiation and hydrocarbon species act for the subsequent CVD growth, high quality graphene has been successfully synthesized at 700 °C by photocatalysis triggered CH4-CVD over a Cu substrate.
