The invention provides a method for quickly depositing graphene on a glass surface through metal-free catalysis. The graphene is quickly deposited on the quartz glass surface by using a chemical vapor deposition (CVD) method under the condition free of an assist of a metal catalyst. The method mainly comprises the following process steps of (1) putting a clean quartz glass sheet on a special bracket, putting the quartz glass sheet and the bracket into a quartz tube and making the glass surface vertical to the horizontal air direction; (2) introducing a carrier gas into the quartz tube, heating the quartz tube to a reaction temperature from a room temperature and introducing a carbon source gas; and (3) quickly growing the graphene on the glass surface through an atmospheric chemical vapor deposition method under the condition free of the assist of the metal catalyst. The process is simple in process and easy to operate; and the conductivity of the graphene glass surface is improved on the premise of ensuring high light transmittance of the graphene glass. The graphene conductive glass with good light transmittance has potential application in multiple fields, such as a photocatalytic substrate and an anti-fog window.
