a Arrhenius plot of the hydrogenation of 1a. Reaction conditions: Fe2P NC/TiO2 (0.1 g, Fe: 1.9 mol%), 1a (2 mmol), 2-propanol (3 mL), H2 (4 MPa), 432–453 K, 2 h. b Double logarithm plots of the concentration of 1a and the initial reaction rate. c Double logarithm plots of the partial pressure of H2 and the initial reaction rate. Reaction conditions: Fe2P NC/TiO2 (0.1 g, Fe: 1.9–15.2 mol%), 1a (0.25–2 mmol), 2-propanol (3 mL), H2 (1–4 MPa), 453 K, 2 h. The plots denote the data mean values, and the error bars show the range. d H2–D2 exchange experiments. Red, blue, green, and yellow show the results obtained by Fe2P NCs, Fe2P NC/TiO2, Fe2P NC/SiO2, and Fe2P NC/C, respectively.
