▎ 摘　　要

NOVELTY - A titanium dioxide solution of graphene comprises 87-92 wt.% distilled water, 2-4 wt.% titanium dioxide, 5-7 wt.% graphene and 1-2 wt.% carbon nano-tube. USE - As titanium dioxide solution of graphene used for decomposition of harmful indoor gases e.g. formaldehyde. ADVANTAGE - The titanium dioxide as a photocatalyst, can easily break down formaldehyde, benzene, ammonia, sulfur dioxide, carbon monoxide, nitrogen oxides and other harmful indoor gases; and accelerates the decomposition of formaldehyde and indoor pollutants. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the solution involving mixing modified graphene, modified titanium dioxide and carbon nano-tube, adding distilled water, stirring for 1-2 hours to obtain the graphene solution, heating to 65-120 degrees C to dissolve graphite, cooling to room temperature, and filtering.
