Embodiment 1

[0026] A higher cadmium cadmium cadmium catalyst with a higher light catalytic activity is a hollow micron ball structure. Among them, sulfur and cadmium are calculated, that is, sulfur: cadmium: 1: 1.

[0027] The preparation method of a higher cadmium cadmium sulfide light catalyst with higher light catalysis above includes the following steps:

[0028] 0.1molch 3 Nsch 3 And 0.1molcd (NO 3 Cure 2 · 4H 2 O dissolved in 40ml ethanol. After stirring for 2h, the powder is completely dissolved and the transfer is turned into a high -pressure kettle with a volume of 50ml to seal;

[0029] Subsequently, the reaction solution was heated to 150 ° C, the constant temperature was 24h, and after the temperature was naturally cooled to the room temperature, the yellow and the water -free ethanol were washed yellow to precipitate it to the neutrality of the outflow liquid;

[0030] Finally, it was dried in a vacuum at 80 ° C, that is, the cadmium sulfide catalyst with a higher catalytic activ...

Abstract

The invention discloses a cadmium sulfide photocatalyst with high photocatalytic activity and a preparation method thereof. The cadmium sulfide photocatalyst has a hollow micro-sphere structure. According to the preparation method, an alcohol-thermal method is utilized, and the preparation method comprises the following steps of: taking ethanol as a solvent, adding a sulfur source and a cadmium source into the solvent, transferring into a high-pressure kettle, controlling the temperature to be 150 DEG C, carrying out a heating reaction, naturally cooling to a room temperature, washing the obtained precipitate until the effluent is neutral, performing vacuum drying to obtain the cadmium sulfide photocatalyst. According to the cadmium sulfide photocatalyst with high photocatalytic activity, the reaction activity when the photocatalytic degradation is conducted on organic pollutants such as methylene blue is high; and moreover, the preparation method is easy and feasible, the production cost is low, pollution does not exist in the production process, and the cadmium sulfide photocatalyst is suitable for industrial large-scale production.

Description

Technical field [0001] The invention is a photocatalytic technology in environmental pollution control. It is specifically a cadmium sulfide light catalyst and preparation method with higher light catalytic activity. technical background [0002] The optical catalytic technology has become one of the research hotspots of solar energy use with its advantages of easy operation, pollution -free, and direct use of sunlight.The hollow ball of nano structure is an important research field in the nano structure system in recent years. Because the hollow micro -ball material has a series of characteristics such as low density, high ratio area, and good filterability, and the hollow part can accommodate a large number of objective molecules or large large molecules or large large partsThe size of the size can produce some strange properties based on the micro -"package" effect, as the load, coatings, paint, catalysts, and drug transmission, capsules and supports, or as a "cage cage that r...
