Abstract

A catalyst material for use at elevated temperatures is provided. The material can include a plurality of fibers and a plurality of particles supported on the fibers. In addition, a porous layer can cover the plurality of particles and allow for process fluid to come into contact with the particles, and yet retard sintering of the particles at elevated temperatures is present. The plurality of fibers can be a plurality of nanofibers which may or may not be oxide nanofibers. The particles can be metallic nanoparticles and the porous layer can be a porous oxide layer.
