Deciphering the relationship between active-site structure and CO2 methanation mechanism over Ni-based catalysts faces great challenges. Herein, different distributions of frustrated Lewis pair (FLP) structures were precisely fabricated Ni/CeO2-nanorods, Ni/CeO2-nanocubes, Ni/CeO2-nanooctahedra to make progress in this issue. Ni/CeO2-nanorods presented highest possibility for FLP construction among these due their CeO2 (110) nature steric hindrance oxygen vacancy (OV) hydroxyl species (OH)....
Modulation of A-site defects is crucial to the redox reactions on ABO3 perovskites for both clean air application and electrochemical energy storage. Herein we report a scalable one-pot strategy in situ regulation La vacancies (VLa ) LaMnO3.15 by simply introducing urea traditional citrate process, further reveal fundamental relationship between VLa creation surface lattice oxygen (Olatt activation. The underlying mechanism shortened Mn-O bonds, decreased orbital ordering, promoted MnO6...
Catalytic combustion is an advanced technology to eliminate industrial volatile organic compounds such as toluene. In order replace the expensive noble metal catalysts and avoid aggregation phenomenon occurring in traditional heterogeneous interfaces, designing homogeneous interfaces can become emerging methodology enhance catalytic performance of oxide catalysts. A mesocrystalline CeO2 catalyst with abundant Ce-Ce synthesized via a self-flaming method which exhibits boosted for toluene...
Simultaneous catalytic elimination of nitrogen oxides (NOx, x = 1 and 2) volatile organic compounds (VOCs) is great importance for environmental preservation in China. In this work, the interactions simultaneous removal NOx methylbenzene (PhCH3) were investigated on a CeO2–TiO2 mixed oxide catalyst, which demonstrated excellent bifunctional efficiencies two pollutants.

The spillover of oxygen species is fundamentally important in redox reactions, but the mechanism has been less understood compared to that hydrogen spillover. Herein Sn doped into TiO2 activate low-temperature (<100 °C) reverse Pt/TiO2 catalyst, leading CO oxidation activity much higher than most oxide-supported Pt catalysts. A combination near-ambient-pressure X-ray photoelectron spectroscopy, situ Raman/Infrared spectroscopies, and ab initio molecular dynamics simulations reveal triggered...
Metal oxide catalysts like CeO2 exhibit promising prospects to replace the currently used noble metal in catalytic oxidation of volatile organic compounds (VOCs). Although oxygen vacancy is regarded as an active site these novel VOC elimination (e.g., toluene), its actual function and activity remain unclear due limitation following dynamic evolution during reactions. Meanwhile, because involves generation–consumption cycle reactive species rather than being constant, this barrier causes a...
To realize an energy storage transition beyond Li-ion competitive technologies, earth-abundant elements, such as Mg, are needed. Carborane anions particularly well-suited to realizing magnesium-ion batteries (MIBs), their inert and weakly coordinating properties beget excellent electrolyte performance. However, utilizing these materials in actual electrochemical cells has been hampered by the reliance on Mg2+ salts of commercially available [HCB11H11]− anion, which is not soluble more...

A Cu/SSZ-13 catalyst containing predominately Z2Cu sites is prepared. Using FTIR spectroscopy, two nonsteady-state measurements, (1) continuous NO titration of an NH3 saturated and (2) intermittent on/off cycles during quasi-steady state (i.e., perturbation), are conducted to shed light on active sites, reaction intermediates, possible mechanisms. During titration, a strong inhibition effect found, where Cu ligands less than depleted ligands. In the perturbation experiments, it demonstrated...
