摘　　要：制备了一系列硼掺杂的还原氧化态石墨烯催化剂并应用于蒽加氢反应。结果表明,随着催化剂处理温度的升高,催化剂中有序碳结构会发生变化,硼会取代材料骨架中的碳,进而影响蒽和氢气的吸附活化。经硼改性后,催化剂对蒽加氢反应表现出了很高的加氢活性,蒽的最高转化率可达97%,深度加氢产物八氢蒽的最高选择性可达19%。A series of boron doped reduced graphene oxide catalysts were prepared and applied to anthracene hydrogenation.The results show that,with the change of the treatment temperature of the catalyst,the ordered carbon structure in the catalyst changed and boron replaced the carbon in the material skeleton,which affected the adsorption and activation of anthracene and hydrogen.After boron doping,the catalyst showed higher activity for anthracene hydrogenation reaction,the highest conversion of anthracene was up to 97%,and the highest selectivity of deep hydrogenation product octahydroanthracene was up to 19%.
