Abstract：Aiming at the problemof poor hydrogen production efectandcyclestabilityof traditional photocatalytic materials，anew preparation method of titanium-based compositephotocatalytic materials was proposed.Firstly，the ratio of photocatalyst was optimized，and then the photocatalytic hydrogen production performanceof theoptimized photocatalyst was analyzed.The results show that the titanium-based composite photocatalyst prepared with 0.6% （204号 graphene oxide has the best photocatalytic performance.At this time，the hydrogen production rate is 1454μmol ·g-1⋅h-1 ，and the photocatalytic quantum efficiency is 4.92% .After5 cycles，the hydrogen production rate of the titanium-based composite photocatalyst is about 1 355μmol⋅g-1⋅h-1 ，showing good photocatalytic activity and cycle stability.Comparing the hydrogen production performance of the titanium-based composite photocatalyst prepared in this experiment with other reported photocatalysts，the hydrogenproductionrate of the titanium-based composite photocatalyst prepared inthis experimentissignificantlybeterthan thatof otherreportedcatalysts，showing obvious advantages in hydrogen production catalytic activity.
