In this section, we systematically tested the catalytic effect of the reaction in the range of 40-120℃ to explore the effect of temperature change on the hydrogenation reaction of BN. As shown in Fig. , as the temperature increases from 40 ℃ to 80 ℃, the substrate conversion rate increases from 80.89% to >99% respectively, and the selectivity gradually increases from 66.42% to >99%. Both benzylamine and dibenzylamine generated by the hydrogenation of BN can be further hydrogenated to form toluene. In this temperature test range, the selectivity of the byproduct toluene is low and almost negligible, proving that a suitable catalyst can effectively improve the selectivity of the target product.
