Understanding complete oxidation of methane on spinel oxides at a molecular level.
It is reported that the higher catalytic activity at the relatively low temperature results from the integration of nickel cations, cobalt cations and surface lattice oxygen atoms/oxygen vacancies at the atomic scale. Expand
Synergy of Single-Atom Ni1 and Ru1 Sites on CeO2 for Dry Reforming of CH4.
A synergy effect of two sets of single-atom sites (Ni1 and Ru1) anchored on the surface of a CeO2 nanorod, demonstrating a new method for designing a catalyst with high activity and selectivity at a relatively low temperature. Expand
Low-Temperature Transformation of Methane to Methanol on Pd1 O4 Single Sites Anchored on the Internal Surface of Microporous Silicate.
Thermodynamic calculations suggest that the reaction toward methanol production is highly favorable compared to formation of a byproduct, methyl peroxide. Expand
WGS catalysis and in situ studies of CoO(1-x), PtCo(n)/Co3O4, and Pt(m)Co(m')/CoO(1-x) nanorod catalysts.
Water-gas shift (WGS) reactions on Co3O4 nanorods and Co3O4 nanorods anchoring singly dispersed Pt atoms were explored through building correlation of catalytic performance to surface chemistry ofExpand
Single rhodium atoms anchored in micropores for efficient transformation of methane under mild conditions
The first C–H bond of CH4 is activated by Rh1O5 anchored on the wall of micropores of ZSM-5; the formed CH3 then couples with CO and OH, to produce acetic acid over a low activation barrier. Expand
Probing the low-temperature water-gas shift activity of alkali-promoted platinum catalysts stabilized on carbon supports.
In situ atmospheric-pressure X-ray photoelectron spectroscopy experiments demonstrated that oxidized platinum Pt-OHx contributions in the Pt 4f signal are higher in the presence of sodium, providing evidence for a previously reported active-site structure of the form Pt-Nax-Oy-(OH)z. Expand
Catalytic Conversion of Carbon Dioxide to Methane on Ruthenium–Cobalt Bimetallic Nanocatalysts and Correlation between Surface Chemistry of Catalysts under Reaction Conditions and Catalytic
Catalytic conversion of CO2 to CH4 on cobalt oxide and Ru-doped cobalt oxide nanorods was studied with in-house ambient pressure X-ray photoelectron spectroscopy (AP–XPS) using monochromated Al Kα. AExpand
Catalysis on singly dispersed bimetallic sites.
It is reported that isolated Rh1Co3 bimetallic sites exhibit a distinctly different catalytic performance in reduction of nitric oxide with carbon monoxide at low temperature, resulting from strong adsorption of twoNitric oxide molecules and a nitrous oxide intermediate on Rh1 Co3 sites and following a low-barrier pathway dissociation to dinitrogen and an oxygen atom.

Catalysis and In Situ Studies of Rh1/Co3O4 Nanorods in Reduction of NO with H2
Efficient use of precious metal atoms in heterogeneous catalysis is important in chemical transformation and environmental remediation. Co3O4 with singly dispersed Rh atoms, Rh1/Co3O4, wasExpand
Intermetallic structures with atomic precision for selective hydrogenation of nitroarenes
Abstract Bridging the structure-properties relationship of bimetallic catalysts is essential for the rational design of heterogeneous catalysts. Different from random alloys, intermetallic compoundsExpand
