Figure 4. (A) The structural model of N2H4 adsorption on Pt(311), Pt(111), and Pt(100) planes, and the corresponding CDDA, where the yellow and cyan regions indicate the accumulation and depletion of the charge, respectively; (B) Free energy profiles of stepwise dehydrogenation of N2H4 on different Pt planes; (C) Proposed pathway of the HzOR on Pt(311). The pink, blue and grey balls represent Pt, N and H atoms, respectively.
