Abstract: The present invention relates yolk-shell nanoparticles having both a high stability towards sintering and high H25 adsorption capacities, the use of the yolk-shell nanoparticles in a method for H2S removal from gas streams, and a corresponding method for H2S removal from gas streams also comprising the regeneration of the yolk-shell nanoparticles, wherein the yolk-shell nanoparticles provide for high H2 adsorption capacities and/or high reusability.

Abstract: Embodiments include hydrogenating catalysts and methods of making the same. The catalyst includes nanoparticles of a metal phosphide, such as nickel phosphide with a Ni5P4 phase. Also included are methods of hydrogenating a gas that contains sulfur. The methods include directing the gas containing sulfur to a catalyst that includes nanoparticles of a metal phosphide, and contacting the catalyst with the gas containing sulfur to produce a hydrogenated gas.
