Controlling the interactions between atomically dispersed metal atoms and support plays significant roles in determining activity selectivity of single-atom catalysts. In this report, we tuned local coordination environment Rh single on CeO2 via calcination to construct a highly active hydroformylation catalyst. Single-atom Rh/CeO2 calcined at high temperature exhibits more oxygen vacancies, which lead formation large amount low-coordination species that are for hydroformylation. Under...
Cu/ZnO/Al2O3 catalysts are widely used in methanol synthesis due to their low cost and high catalytic activity. The structural surface characteristics of Cu crucial the formation active sites for production. In this study, a series methods employed modulate catalyst structure efficiency hydrogenation CO2 methanol. A correlation activity with Cu0 area particle sizes has been established. derived from hydrotalcite-like precursor (CZA-LDH) exhibits maximum specific area, smallest size,...
Controlling the selectivity of CO2 hydrogenation by catalysis is a fundamental challenge. This study examines interrelation between active sites and reaction pathways in Ni-catalyzed hydrogenation. The alloying Ni with Zn to charged (Niσ––Znσ+) modifies electronic structure d-band center, weakens interaction CO/H2, preferentially catalyzes reverse water gas shift CO thermodynamically favored methanation pathway switched off. dual can stabilize activated species η2(C, O) bridge configuration,...
A Cu-based catalyst has prospects for practical use in selective hydrogenation of CO2 to methanol. But the catalyst's structural complexity renders elucidation nature active sites a challenge. This work reports CuGaZrOx solid solutions with tunable Cu size scales and synergetic interactions between methanol synthesis. Atomically dispersed species (Cu1–O3) adjacent Zr site contribute enhanced capacity adsorption/activation, Ga are primarily responsible H2 dissociation over solution isolated...
Nickel-based catalysts are the most promising selection for CO2 methanation. But, it is challenging monometallic Ni to achieve high conversion at low temperature. This study develops ceria-supported bimetallic Ni–Ru that highly efficient low-temperature A small amount of Ru (0.2 wt %) addition enables intermetal interaction, and enhances dispersion particles with a more active surface, consequently boosting catalytic capacity hydrogen activation CO adsorption. The exhibit than 3-fold rate...
The water-gas shift (WGS) reaction is often conducted at elevated temperature and requires energy-intensive separation of hydrogen (H2 ) from methane (CH4 ), carbon dioxide (CO2 residual monoxide (CO). Designing processes to decouple CO oxidation H2 production provides an alternative strategy obtain high-purity streams. We report electrothermal WGS process combining thermal on a silicomolybdic acid (SMA)-supported Pd single-atom catalyst (Pd1 /CsSMA) electrocatalytic evolution. two...
The metal–oxide interaction in heterogeneous catalysis is of significance to fundamental studies and practical applications. This study examines the catalytic role Cu–ZrO2 mechanistic pathways CO2 hydrogenation methanol. A series catalysts with different extents are achieved via tuning component (Cu ZrO2) particle sizes over Cu/ZrO2 inverse ZrO2/Cu catalysts. methanol synthesis from does not exclusively depend on metallic Cu sites or surface oxides but rather extent between metal oxide....
Abstract This article describes a strategy for increasing oxygen storage capacity (OSC) of ethanol steam reforming (ESR) catalysts. Sintering and carbon deposition are major defects nickel‐based catalysts ESR; tuning mobility (OM) CeO 2 ‐based supports can overcome these drawbacks promote H production. We have successfully increased OSC OM by adding Mg into the lattice Ni/CeO to production in ESR. The insertion efficiently promotes reduction Ce 4+ according X‐ray powder diffraction (XRD)...
