But the sunlight utilization rate of above-mentioned existing photocatalyst and catalysis oxidability are the highest.
Summary of the invention
The technical problem to be solved is, the shortcoming overcoming above prior art: provide a kind of sunlight utilization rate high and catalysis oxidability is strong is mainly used in photocatalytic self-cleaning, degradable organic pollutant and the TiO of antibacterial virus of going out2/MnS/Ga2O3Composite photocatalyst colloid preparation method.
The technical solution of the present invention is as follows: a kind of TiO2/MnS/Ga2O3Composite photocatalyst colloid preparation method, comprises the following steps:
1) synthesis TiO2Colloidal sol: first titanium salt is dissolved in dehydrated alcohol, then the salpeter solution of be configured to deionized water 1～5w% is heated to 10～90 DEG C, under agitation instill the above-mentioned dehydrated alcohol having dissolved titanium salt, drip off latter continuously stirred 4～24 hours, obtain light blue transparent TiO2Colloid, described TiO2TiO in colloid2Content controls 1.0～7.0wt%；
2) synthesis Ga2O3Colloidal sol: be first dissolved in the salpeter solution of 4～8wt% by Ganite (Fujisawa)., stirs and is heated to 10～50 DEG C, under agitation instilling ammonia, after dripping off ammonia the most continuously stirred 10～48 hours, obtains the Ga of pale yellow transparent2O3Colloid, described Ga2O3Ga in colloid2O3Content controls 0.1～2.0wt%；
3) synthesize cotton-shaped MnS: be first dissolved in deionized water by manganese salt and be configured to the solution that concentration is 1～8wt%, then in above-mentioned solution, instill TAA, be filtrated to get cotton-shaped MnS；
4) TiO2/MnS/Ga2O3Composite photocatalyst colloid synthesize: by step 1), step 2) prepared by TiO2Colloidal sol, Ga2O3Colloidal sol mixes, continuously stirred 1～6 hour；Then by mixture by circulation dialysis to pH=2～6, obtain TiO2/Ga2O3Composite colloid；Again by described TiO2/Ga2O3The cotton-shaped MnS mixing of composite colloid and step 3)；Final prepared solid content is the TiO of 2～4wt%2/MnS/Ga2O3Composite photocatalyst colloid, wherein, TiO2/MnS/Ga2O3Composite photocatalyst colloid dry after solid in TiO2Content 90.0～97.0 wt%, MnS content 2.9～8.0 wt%, Ga2O3Content 0.1～2.0 wt%.
