▎ 摘 要
NOVELTY - Composite photocatalyst, comprises 80-98 pts wt. bismuth-rich oxybromide, 1-10 pts. wt. polyaniline, and 1-5 pts. wt. graphene oxide. USE - The composite photocatalyst is useful in producing hydrogen (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite photocatalyst comprises introducing bismuth-rich oxybromide to polyaniline and graphene oxide solution to synthesize the bismuth-rich oxybromide compound, polyaniline and graphene oxide composite photocatalyst. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electroscope diagram of the bismuth oxybromide according to example 1.
