Abstract
A multifunctional self-cleaning surface layer and methods of preparing the multifunctional self-cleaning surface layer are provided. The multifunctional self-cleaning surface layer includes an inorganic matrix including silicon and oxygen; a plurality of photocatalytic active particles distributed within and bonded to the inorganic matrix; and a plurality of nanopores defined within the inorganic matrix in regions corresponding to bonds between the plurality of photocatalytic active particles and the inorganic matrix. Water molecules may be disposed within at least a portion of the plurality of nanopores. In the presence of water and electromagnetic radiation, the plurality of photocatalytic active particles may facilitate a decomposition reaction of any oil or organic residue on the multifunctional self-cleaning surface layer.
