NOVELTY - A two-dimensional titania nanomaterial template is prepared by dissolving 0.035-0.4 g graphene oxide in 80 ml ethanol solution, adding 60-100 ml ethanol, 2-4 g dodecylammonium bromide and 3-6 ml concentrated nitric acid, mixing, adding 15-35 ml ethanol and 15-35 ml tetrabutyl titanate, mixing, reacting under high pressure, washing precipitate with ethanol for 3-4 times, performing hydrogen treatment, and roasting in presence of air. USE - Method for preparing two-dimensional titania nanomaterial template (claimed) used as anode material in dye-sensitized solar cells. ADVANTAGE - The two-dimensional titania nanomaterial has high photoelectric conversion efficiency.
