Abstract

Ni films with a thickness of 700-800 nm were deposited on carbon fiber layers using electroless deposition, and surface structures and chemical properties of these films with various annealing temperatures (300, 600 and $900^{\circ}C$) were studied. $600^{\circ}C$-annealing under atmospheric conditions resulted in formation of porous surface structures with a mean pore size of ~100 nm, whereas the other samples showed non-porous surface structures. $600^{\circ}C$-annealed Ni film showed much higher reactivities for toluene adsorption and CO oxidation comparing to other non-porous surfaces.
