▎ 摘  要

NOVELTY - Preparing vitreous composite layers, comprises: synthesizing precursor suspension by successive operations of forming a stock solution SI of reduced graphene oxide (rGO) in anhydrous ethylene glycol solvent; adding 1/3 SI titanium tetra isopropoxide and triethyl phosphate, respectively under magnetic stirring for 1 hour and 30 minutes, respectively, 1/3 SI dimethylformamide, and 1/3 SI, 35% hydrochloride under magnetic stirring for 10 minutes each; adding distilled water (as drops) to the final suspension for 60 minutes under stirring at a speed of 500 rpm, to result in a composite layer that is deposited on an indium and tin (ITO)/glass substrate by spin coating at speeds of 5000-7000 rpm, respectively; and thermal treatment in two steps, with an accelerated increase of temperature to carry out the vitreous matrix, to result in titanium dioxide-phosphorus pentoxide-rGO composite layers on ITO/glass substrate. USE - The process is useful for preparing vitreous composite layers which are used as photoanodes in dye-sensitized solar cells. ADVANTAGE - The process provides vitreous composite layers that exhibit photocatalytic properties.
