Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.

Correlation Between the Molecular Structure of Metal‐Supporting Ligands and Catalysis in the Oxygenase‐Mimicking Immobilized Metal Complex Catalysts

European Journal of Inorganic Chemistry, EarlyView.
The correlation between the structures of metal complexes immobilized in the mesopores of hydrophobically modified silicate supports was examined in relation to the catalytic activities toward C‐H oxidation. On the alkene oxidation with H2O2, the iron catalyst bearing bis(imidazolyl)methane ligand promotes allylic oxidation, whereas the mononuclear ...

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...
