Nanoceria Supported Single-Atom Platinum Catalysts for Direct Methane Conversion

Journal Article Xie, Pengfei [Johns Hopkins Univ., Baltimore, MD (United States). Dept. of Chemical and Biomolecular Engineering]; Pu, Tiancheng [Johns Hopkins Univ., Baltimore, MD (United States). Dept. of Chemical and Biomolecular Engineering]; Nie, Anmin [Shanghai Univ., Shanghai (China). Shanghai Univ. Materials Genome Inst. and Shanghai Materials Genome Inst.]; ... - ACS Catalysis

Nanoceria-supported atomic Pt catalysts (denoted as Pt₁@CeO₂) have been synthesized and demonstrated with advanced catalytic performance for the non-oxidative, direct conversion of methane. These catalysts were synthesized by calcination of Pt-impregnated porous ceria nanoparticles at high temperature (ca. 1,000 °C), with the atomic dispersion of Pt characterized by combining aberra-tion-corrected high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM), X-ray photoelectron spectroscopy (XPS), X-ray absorption spec-troscopy (XAS) and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) analyses. The Pt₁@CeO₂ catalysts exhibited much superior catalytic performance to its nanoparticulated counterpart, achieving 14.4% of methane conversion at 975 °C and 74.6% selectivity toward C₂more » « less

Noble metal catalysts and processes for reforming of methane and other hydrocarbons

Patent Marker, Terry L.; Linck, Martin B.; Wangerow, Jim; ...

Processes for converting methane and/or other hydrocarbons to synthesis gas (i.e., a gaseous mixture comprising H₂ and CO) are disclosed, in which at least a portion of the hydrocarbon(s) is reacted with CO₂. At least a second portion of the methane may be reacted with H₂O (steam), thereby improving overall thermodynamics of the process, in terms of reducing endothermicity (ΔH) and the required energy input, compared to “pure” dry reforming in which no H2O is present. Catalysts for such processes advantageously possess high activity and thereby can achieve significant levels of methane conversion at temperatures below those used conventionally undermore » « less

A method of manufacturing a bifunctional electrocatalyst for overall water splitting comprising oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) by growing electrocatalyst comprising primarily metallic phosphides on a three-dimensional substrate by: immersing the substrate in an iron nitrate solution to form a once disposed substrate; subjecting the once disposed substrate to thermal phosphidation with phosphorus powder under inert gas to grow metal phosphides thereupon and form a once subjected substrate; cooling the once subjected substrate to form a cooled, once subjected substrate; immersing the cooled, once subjected substrate in an iron nitrate solution to form a twice disposedmore » « less
