Classification: CPC C  G | IPC C  G

Claim 0:
1. A sol-gel method for forming a self-cleaning coating comprising plasmonic nanoparticles dispersed in a photocatalytic matrix, the method comprising:
a. providing a first dispersion comprising the plasmonic nanoparticles by:
complexing plasmonic nanoparticles, having a size of from 3 nm to 200 nm, with a stabilizing agent suitable for stabilizing the dispersion of the plasmonic nanoparticles in an organic solvent, by complexing the plasmonic nanoparticles with a first stabilizing agent for stabilizing the plasmonic nanoparticles in an aqueous medium and subsequently exchanging the first stabilizing agent for a second stabilizing agent for stabilizing the plasmonic nanoparticles in an organic medium, and
suspending the complexed plasmonic nanoparticles in the organic solvent,

b. providing a second dispersion comprising a precursor of the photocatalytic matrix in an organic medium,
c. forming a mixture of the first and second dispersion, wherein forming said mixture comprises forming a sol,
d. coating the mixture on a surface, and
e. calcining the coated mixture.
