Abstract
A method for oxidizing carbon monoxide to carbon dioxide is provided which utilizes specific supported catalyst particles. The supported catalyst comprises catalyst particles that are supported on particles of an electrically conductive support selected from the group consisting of graphitic carbon and a partially reduced oxide of a transition metal of the Magnéli phase selected from the group consisting of titanium, vanadium, zirconium, niobium, molybdenum, and mixtures thereof.
Claims14
A method for oxidizing a carbon monoxide component of a gas to carbon dioxide comprising contacting said gas to supported catalyst particles comprising catalyst particles supported in and/or on electrically conductive support particles of a partially reduced oxide of a transition metal comprising a Magnéli phase selected from the group consisting of titanium, vanadium, zirconium, niobium, molybdenum, and mixtures thereof, wherein said supported particles act in synergy with said catalyst particles for the catalytic combustion of carbon monoxide.
A method for oxidizing a carbon monoxide component of a gas comprising contacting said gas to supported catalyst particles comprising catalyst particles supported in and/or on electrically conductive support particles of a partially reduced oxide of a transition metal comprising a Magnéli phase selected from the group consisting of titanium, vanadium, zirconium, niobium, molybdenum, and mixtures thereof, wherein said support particles act in synergy with said catalyst particles for the catalytic combustion of carbon monoxide, and wherein the gas is selected from the group consisting of mainstream cigarette smoke, sidestream cigarette smoke, vehicle exhaust emission, a gas used in a laser, a gas used in a fuel cell, and ambient air undergoing air filtration.
