Abstract
The present invention provides a method for depositing a catalyst onto a substrate through the use of pulsed laser radiation. A solution is prepared containing the catalyst and the support. The beam from a pulsed laser whose wavelength is such that it is absorbed by the catalyst is directed into the liquid. The laser reduces the catalyst particle size and allows it to be deposited as a film or as small diameter particles onto the support thereby giving a catalyst with enhanced activity.
