SULFUR-FREE PLATINUM CATALYST FOR HYDROGEN PRODUCTION

Abstract: this disclosure provides systems and methods related to a pt/tiocatalyst. in one aspect water with a platinum precursor dissolved therein is mixed with tionanoparticles. the tionanoparticles with the platinum precursor disposed thereon are heat treated in air to form platinum oxide nanoparticles disposed on the tionanoparticles. the tionanoparticles are deposited on a tiosubstrate to form a structure. the structure is reduced to form platinum nanoparticles disposed on the tionanoparticles, including: heat treating the structure at about 375� c. to 450� c. with hydrogen being present; cooling the structure from about 375� c. to 450� c. to about 350� c. at about 2� c./minute with hydrogen being present; and cooling the structure from about 350� c. to room temperature at about 1� c./minute to 5� c./minute with hydrogen being present. after the reduction operation, the structure is heat treated in an atmosphere including methylcyclohexane.
