▎ 摘  要

NOVELTY - Preparing composite material, involves mixing echinus-shaped zinc oxide with tetrabutyl titanate to form zinc oxide-titanium dioxide composite material. Graphene oxide, sodium citrate, silver nitrate and water are mixed to obtain silver system which is mixed with zinc oxide-titanium dioxide composite material and polycationic compound to obtain after ultrasonic surface modification echinus-shaped composite material. USE - Method for preparing composite material which is used in dye-sensitized cells, calcium titanium batteries and also for photo-degradation of organic pollutants (claimed). ADVANTAGE - The method enables to prepare echinus-shaped composite material in a simple and cost effective manner suitable for industrial production. The product shows high photoelectric performance.
