CATALYST LAYERS AND RELATED METHODS

摘要

Disclosed is a method of preparing a catalyst and a resultant coated substrate. An example method for preparing a catalyst includes dissolving a precursor salt in water to create a dissolved precursor salt. In addition, the method includes adding an ultra-violet sensitizer to the dissolved precursor salt to create a photo emulsion and mixing the photo emulsion with at least one of a surfactant or a stabilizer to create a modified photo emulsion. Further, the modified photo emulsion is applied to a substrate to create a coated substrate, and then the coated substrate is exposed to ultra-violet light. Further, the example method comprises washing the coated substrate after exposing the coated substrate to ultra-violet light and drying the coated substrate after washing the coated substrate.
