High Loading of Transition Metal Single Atoms on Chalcogenide Catalysts

Journal of the American Chemical Society, 2021
Transition metal doped chalcogenides are one of the most important classes of catalysts that have been attracting increasing attention for petrochemical and energy related chemical transformations due to their unique physiochemical properties. For practical applications, achieving maximum atom utilization by homogeneous dispersion of metals on the ...

Moiré‐Induced Symmetry Breaking of Charge Order in van der Waals Heterostructures

Advanced Materials, EarlyView.
A uniaxial moiré potential in misfit (MS)1+δTaS2 heterostructures selectively reshape charge order: the embedded 1H‐TaS2 layer hosts an incommensurate charge‐density wave, fragmented into nanometer domains and stripped of threefold symmetry. Superconductivity, however, remains uniform and fully gapped, revealing heterosymmetry stacking as a selective ...

Regulating Phase Evolution and Crystallization Dynamics Enables Low Open‐Circuit Voltage Deficit in Wide‐Bandgap Cu2ZnSnS4 Solar Cells

Advanced Materials, EarlyView.
Bilayer composition‐modulated sulfurization (BCMS) regulates Cu redistribution in solution‐processed Cu2ZnSnS4, suppressing Cu2SnS3 and favoring the direct transformation pathway, while transforming the crystallization from surface‐dominated growth to a more synchronized process.
