Description
Technical field
The present invention relates to the hydro-thermal method synthetic method of a kind of nano-zinc sulfide/bamboo charcoal catalysis material.
Background technology
Semiconductor as a kind of important broad stopband, zinc sulfide nano-material is because of its unique character, had in fields such as light-guide material, luminescence generated by light, photocatalysis widely and used, particularly in photocatalysis field, advantages such as it has the photocatalytic activity height, chemical property is stable, nontoxic no burn into cost is low, service life is long, but it is not high to exist the difficulty and the efficiency of light energy utilization of separating and reclaiming in the use of powdery nano-zinc sulfide; Limited the practical application of photocatalysis technology, and bamboo charcoal is as a kind of novel environment-friendly materials and function material, because of its flourishing pore structure, specific area is big, and absorption power is strong, has adsorption function, can be used as good carrier, is the carrier of nano-zinc sulfide with the bamboo charcoal, helps the recycling of catalyst, reduce processing cost, synthetic, sign and the photocatalysis performance of therefore studying nano-zinc sulfide/bamboo charcoal compound are significant.
Summary of the invention
The objective of the invention is with the white vitriol is that zinc source, thiocarbamide are that sulphur source, polyethylene glycol are that dispersant, bamboo charcoal are carrier, adopts the synthetic nano-zinc sulfide/bamboo charcoal composite with high efficiency photocatalysis performance of one step hydro thermal method.
Concrete steps are:
(1) takes by weighing the white vitriol of 0.0028-0.0560g and the polyethylene glycol of 0.05-0.15g-6000 is dissolved in the distilled water of 30ml, and place that the dissolving of room temperature stirring at low speed makes even mixed liquor on the magnetic stirrer;
(2) take by weighing the 0.1-2.0g bamboo charcoal and put into above-mentioned mixed liquor, stir about 3h; The thiocarbamide that adds 0.0015-0.0300g again continues to stir about 3h;
(3) be in the autoclave of inner liner polytetrafluoroethylene of 40ml at last with step (2) gained solution importing capacity, and be placed in the digital display air dry oven with constant temperature 150-160 ℃ of reaction 10-12h, naturally cool to room temperature then, filter, drying promptly makes nano-zinc sulfide/bamboo charcoal catalysis material, the ZnS nano particle is the hexagonal crystal phase in nano-zinc sulfide/bamboo charcoal catalysis material, sphere, and average grain diameter is about 100nm.
