Nanoparticle catalyst preparation using pulsed arc plasma deposition

A novel nanoparticle preparation technique using pulsed arc plasma deposition has been developed as a dry catalyst preparation process in complete contrast to conventional wet processes. An overview of the principle, fundamental features of the technique and a discussion of the recent progress are presented using examples from our recent publications. The potential for preparing several types of supported metal and metal oxide catalysts with higher activities at minimum metal loadings is also highlighted.
