Abstract
Methods of synthesizing Bi2S3—CdS particles in the form of spheres as well as properties of these Bi2S3—CdS particles are described. Methods of photocatalytic degradation of organic pollutants employing these Bi2S3—CdS particles and methods of preventing or reducing microbial growth on a surface by applying these Bi2S3—CdS particles in the form of a solution or an antimicrobial product onto the surface are also specified.
Claims6
A method for degrading an organic pollutant, the method comprising:
- contacting Bi2S3—CdS particles with an aqueous solution comprising the organic pollutant to form a mixture;
- illuminating the mixture with a light at a wavelength in a range of 200-700 nm for 0.1-6 hours thereby degrading the organic pollutant;
- wherein:
- the Bi2S3—CdS particles comprise bismuth(III) sulfide and cadmium(II) sulfide;
- the Bi2S3—CdS particles are in the form of spheres with an average diameter of 0.3-5 μm;
- and
- the organic pollutant is present in the aqueous solution at a concentration of 1-1,000 mg/L relative to a total volume of the aqueous solution.
