Claim 0:
1. A method of degrading adsorbed dye molecules on a metal/metal oxide nanocomposite substrate, the method comprising:
step 1: detecting a presence of the adsorbed dye molecules on a surface area of the substrate by using an ultrasensitive optical method; and
step 2: irradiating the surface area of the substrate with UV-visible light to degrade the adsorbed dye molecules;
step 3: confirming an absence of the adsorbed dye molecules on the surface area of the substrate by using an ultrasensitive optical method;
step 4: repeating steps 1-3 on different surface areas of the substrate;
step 5: sonicating the substrate;
step 6: after the sonicating step, confirming an absence of the adsorbed dye molecules for each of the surface areas of the substrate by using the ultrasensitive optical method;
step 7: after step 6, repeat step 2 for each of the surface areas of the substrate; and
step 8: after step 7, confirm an absence of the adsorbed dye molecules for each of the surface areas of the substrate by using the ultrasensitive optical method.
