Abstract
Official abstract text for this publication.
The present invention provides a method for preparing nanoporous Pt/TiO 2 composite particles, nanoporous Pt/TiO 2 composite particles prepared by the above preparation method, and a fuel cell comprising the nanoporous Pt/TiO 2 composite particles. The nanoporous Pt/TiO 2 composite particles according to the present invention have a catalytic effect similar to that of commercially available Pt/carbon black and, thus, can be applied to a fuel cell.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for preparing nanoporous metal/ceramic composite particles for a fuel cell, the method comprising: (a) preparing an aqueous colloidal solution by mixing metal nanoparticles and ceramic nanoparticles in water; (b) atomizing the colloidal solution of step (a) into aerosol droplets by using an ultrasonic atomizer, wherein the aerosol droplets contain an aqueous dispersion of the metal nanoparticles and ceramic nanoparticles; and (c) evaporating the…
