“…Support material have been roughly classified as carbon-based support and non-carbon-based support [20]. Among non-carbonbased material that attract researchers attention were titania [28][29][30][31], alumina, silica [28], ceria [30], zirconia, tungsten oxide and conducting polymers [20]. Non-carbon support improved the reaction kinetics due to the metal-support interaction, however, their electrical conductivity was lower than that of the carbon support.…”
