Tunning valence state of cobalt centers in Cu/Co-CoO1-x for significantly boosting water-gas shift reaction - Nature Communications

Jan 15, 2025 | nature.com | Wei-Wei Wang |Kai Xu |Chun-Jiang Jia |Hao Dong |Guangshe Li |Chen Li

AbstractDual active sites with synergistic valence state regulation under oxidizing and reducing conditions are essential for catalytic reactions with step-wise mechanisms to modulate the complex adsorption sites of reactant molecules on the surfaces of heterogeneous catalysts with maximized catalytic performances, but it has been rarely explored.

Direct cleavage of C=O double bond in CO2 by the subnano MoOx surface on Mo2N - Nature Communications

Oct 23, 2024 | nature.com | Wei-Wei Wang

AbstractCompared to H2-assisted activation mode, the direct dissociation of CO2 into carbonyl (*CO) with a simplified reaction route is advantageous for CO2-related synthetic processes and catalyst upgrading, while the stable C = O double bond makes it very challenging. Herein, we construct a subnano MoO3 layer on the surface of Mo2N, which provides a dynamically changing surface of MoO3↔MoOx (x < 3) for catalyzing CO2 hydrogenation.
Hydroxylated TiO2-induced high-density Ni clusters for breaking the activity-selectivity trade-off of CO2 hydrogenation - Nature Communications

Sep 26, 2024 | nature.com | Wei-Wei Wang |Qiang Fu |Feng Wang |Chao Ma

AbstractThe reverse water gas shift reaction can be considered as a promising route to mitigate global warming by converting CO2 into syngas in a large scale, while it is still challenging for non-Cu-based catalysts to break the trade-off between activity and selectivity.
Catalytic properties of trivalent rare-earth oxides with intrinsic surface oxygen vacancy - Nature Communications

Jul 8, 2024 | nature.com | Kai Xu |Wei-Wei Wang |Chao Ma |Feng Wang |Jun Li |Chun-Jiang Jia

AbstractOxygen vacancy (Ov) is an anionic defect widely existed in metal oxide lattice, as exemplified by CeO2, TiO2, and ZnO. As Ov can modify the band structure of solid, it improves the physicochemical properties such as the semiconducting performance and catalytic behaviours. We report here a new type of Ov as an intrinsic part of a perfect crystalline surface.
Stabilized Inverse Y2O3/Cu Interfaces Boosted the Performance of Reverse Water-Gas Shift Reaction

Apr 22, 2024 | pubs.rsc.org | Zhixin Li |Wei-Wei Wang |Kai Xu |Xin-Pu Fu

Stabilized Inverse Y2O3/Cu Interfaces Boosted the Performance of Reverse Water-Gas Shift Reaction Reverse water-gas shift (RWGS) reaction exhibits the tremendous practical significance for solving energy shortage problems. However, the harsh reaction conditions inevitably lead to sintering of the active metal which resulted in a loss of interface sites. Therefore, constructing efficient and stable catalysts with uniform interfaces in RWGS reaction is the continuing challenge.

Boosting reactivity of water-gas shift reaction by synergistic function over CeO2-x/CoO1-x/Co dual interfacial structures - Nature Communications

Oct 27, 2023 | nature.com | Wei-Wei Wang |Chao Ma

AbstractDual-interfacial structure within catalysts is capable of mitigating the detrimentally completive adsorption during the catalysis process, but its construction strategy and mechanism understanding remain vastly lacking. Here, a highly active dual-interfaces of CeO2-x/CoO1-x/Co is constructed using the pronounced interfacial interaction from surrounding small CeO2-x islets, which shows high activity in catalyzing the water-gas shift reaction.
