3875-3881).In addition, prepare bismuthyl chloride/bismuth sulfide nano flower hetero-junctions process is related to solvent-thermal method, reaction temperature more
Height, process flow is long and complex, and the requirement to equipment is also higher, greatly limits bismuthyl chloride/bismuth sulfide nano flower hetero-junctions
The application (Applied Surface Science, 2014,290,313-319) of photochemical catalyst.Secondly, to improve hetero-junctions
Prepare yield, Many researchers during preparing bismuthyl chloride/bismuth sulfide nano and using up catalyst, using addition NaOH,
KOH、K2CO3、NH3·H2The alkaline matters such as O adjust pH, but alkali is not environment friendly type substance, have strong corrosion to equipment
Effect brings security risk (Catalysis Communications, 2012,26,204-208) to production.Therefore, ring is researched and developed
Cleaning is protected, novel bismuthyl chloride/bismuth sulfide nano of good economy performance uses up the hot spot that catalyst preparation technology has become the field.
The present invention uses a kind of simple wet chemistry method, thio with soluble bismuth salt, sodium chloride or potassium chloride and five hydrations
Sodium sulphate has prepared BiOCl/Bi as raw material, in 20~35 DEG C of conditions of room temperature in next step2S3Nano flower heterojunction structure.This
Kind one step of room temperature prepares BiOCl/Bi2S3The method of nano flower hetero-junctions has not been reported both at home and abroad.And these BiOCl/Bi2S3It receives
Popped rice hetero-junctions has preferable photocatalytic activity under visible light, and potential is huge in terms of administering or repairing ecological environment.This
The BiOCl/Bi of kind method preparation2S3Nano flower heterojunction material is at low cost, synthesis condition is mild, easy to operate, technique is simple
Single, instrument and equipment requires the features such as low, is conducive to large-scale production, has huge application value.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of simple normal temperature conditions to prepare in next step
BiOCl/Bi2S3The method of nano flower heterojunction photocatalysis material.By using soluble bismuth salt, sodium chloride or potassium chloride and five
Sodium thiosulfate is hydrated as raw material, under normal temperature conditions, a step has prepared BiOCl/Bi2S3Nano flower heterojunction photocatalysis
Material, the reaction system are neither related to hot conditions, be not related to yet complicated reaction unit and valuableness organic formwork agent and
Alkaline matter effectively reduces environmental pollution, has saved production cost, is a kind of preparation process of complete green, while again can
Maintain high product yield.The preparation method has that at low cost, reaction condition is mild, instrument and equipment requires that low, yield is high, and easily
In large-scale production many advantages, such as, have wide prospects for commercial application.
The specific technical solution of the present invention is as follows:
It is an object of the invention to overcome deficiency in the prior art, a kind of 20~35 DEG C of conditions next step of room temperature are provided
