Title: Advanced characterization methodology for materials structure and reaction mechanism dynamically and precisely visual detection and determination
Abstract:
We focuses on the common key
scientific issues of material field “Advanced characterization methodology for
materials structure and reaction mechanism dynamically and precisely visual
detection and determination”. The applicant has developed XAS/PDF/XES/XRD/EELS/EXELFS et al. combined with electron
microscopy and corresponding energy spectra, molecular vibration spectrum
ATR-SEIRAS/DRIFTS/Raman/fs-TA/NMR/PALS et al. to achieve in-situ/operando
multi-spectrum for atomically precise materials structure and reaction
mechanism dynamically visual detection and determination methodology. The
definite holographic "structure activity relationship" regarding the
materials structure, valence state and molecule reaction mechanism during
in-situ/operando key energy catalytic process was established[1-10]. Through
mathematical modeling, DFT calculation and AI machine learning data mining,
large materials database regarding the origin and regulation principle of
material properties was built, forming “materials structure and reaction
mechanism dynamically and precisely visual detection and determination” large
materials database driven to accelerate and guide the corresponding
object-oriented high performance new materials "Relay iteration"
rational design and synthesis general methodology platform.
