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.
Claims20
A method for reducing growth of a microorganism on a surface, the method comprising:
- applying Bi2S3—CdS particles onto the surface,
- wherein the Bi2S3—CdS particles comprise bismuth(III) sulfide and cadmium(II) sulfide,
- wherein the Bi2S3—CdS particles are in sphere form,
- wherein the Bi2S3—CdS particles are in contact with the surface for a time period in a range of from 1 to 24 hours, and
- wherein the microorganism is at least one gram-negative bacterium selected from the group consisting of Acinetobacter baumannii, Enterobacter aerogenes, Escherichia coli, Klebsiella oxytoca, and Klebsiella pneumoniae, or
- wherein the microorganism is at least one gram-positive bacterium selected from the group consisting of Staphylococcus aureus, Staphylococcus epidermis, and MRSA.
