Fig. 2. The effects of metal loading for catalytic performance. (a) The influence of Co-loading weight, (b) the influence of secondary transition metals, (c) the influence of different ratio of Cu/Co, (d) H2-TPR of M-3Co/TiO2 catalysts. Reaction conditions: 0.25 g catalyst, 3 MPa H2, 160 °C, 30 mL heptane, 0.5 g isoborneol, 2 h.
