ConspectusSimply yet powerfully, single-atom catalysts (SACs) with atomically dispersed metal active centers on supports have received a growing interest in wide range of catalytic reactions. As specific example, SACs exhibited distinctive performances CO2 chemical conversions. The unique structures are appealing for adsorptive activation molecules, transfer intermediates from support to sites, and production desirable products conversion.In this Account, we exemplified our recent endeavors...
The catalytic performance of Cu/ZnO/Al2O3 (CuZnAl) catalyst for CO2 hydrogenation to methanol was investigated over a period 720 h time-on-stream, which showed that the space time yield CH3OH decreased by 34.5% during long-term testing. Different characterization techniques, including X-ray diffraction (XRD), scanning electron microscopy, high resolution transmission photoelectron spectroscopy (XPS), and N2O adsorption experiments, were applied study deactivation reasons. XRD experiments...
Abstract The activity of Fischer–Tropsch synthesis (FTS) on metal-based nanocatalysts can be greatly promoted by the support reducible oxides, while role remains elusive. Herein, varying reduction condition to regulate TiO x overlayer Ru nanocatalysts, reactivity Ru/TiO 2 differentially modulated. in FTS shows a volcano-like trend with increasing temperature from 200 600 °C. Such variation is characterized related activation CO at interfaces. Further theoretical calculations suggest that...
Strong metal–support interactions (SMSIs) play a crucial role in the catalytic performance of supported metal catalysts. Researchers hypothesize that there is migration support over preexisting nanoparticles during pretreatment. In present work, distinct mechanism generating an SMSI by co-reduction oxide interphase evaluated Ru/TiO2 Formation RuxTi1–xO2 augmented facile manner increasing calcination temperature catalysts, whereas encapsulation TiOx overlayer on metallic Ru occurs subsequent...
The heptamethylbenzenium cation (heptaMB(+)) has been speculated to be one of the most important active intermediates involved in "hydrocarbon pool" mechanism methanol-to-olefin (MTO) conversion. By use DNL-6, a newly synthesized SAPO-type molecular sieve with large cavities, heptaMB(+) for first time directly observed during methanol conversion under real working conditions.

A series of Fe-based catalysts with accurately controlled amounts Na are synthesized to investigate the relationship between promoter and catalytic performance for CO2 hydrogenation alkenes. With increasing amount Na, both conversion alkenes selectivity increase at low moderate then plateau (with highest be 36.8% 64.3%, respectively), while corresponding methane production decreases 7.2%. It is found that addition enhances adsorption CO2, facilitates formation stability active species Fe5C2,...
The Ru/TiO2 catalyst serves as a representative metal/support interaction system with tunable reactivity in catalytic processes. Herein, by varying the metal loadings of Ru from 0.5 to 4 wt % regulate size on support, performances catalysts Fischer–Tropsch synthesis (FTS) can be further refined. An improved FTS activity is acquired when increases, while long carbon-chain products (C5+ hydrocarbons) prefer generated small-sized catalyst. With intensive characterizations, it indicated that...
Exploration of highly selective catalysts for the reverse water-gas shift reaction, which can serve as a pivotal stage transitioning abundant CO2 resources into chemicals or fuels, still remains great challenge.
