What is the DFT found?
(1) Pt plays the role of electron donor transferring electrons to the support; the electron acceptor
(2) WOx play the role of electron acceptor receiving electrons from γ-Al2O3 making electron deficient on from γ-Al2O3. Therefore,
(3) more electron transfer from Pt making the interaction between Pt and γ-Al2O3 is strengthened
