Figure 7. (A) Synthetic route for the construction of Pd1/WO2.72; (B) Catalytic performance of Pd1/WO2.72. Including conversion and selectivity, performance comparison with other similar catalysts, TOF values and recycling performance; (C) Free energy diagrams of vanillin hydrogenation to vanillyl alcohol and 2-methoxy-2-methoxy-p-cresol at 60 °C (blue) and 140 °C (red). The structures of reactants and products are shown above the energy profiles, while the intermediate state structures are shown below the energy profiles. The geometry of Ru1/mpg-C3N4 is shown in the upper right[70]. Copyright 2018 American Chemical Society. TOF: The turnover frequency.
