Two novel molybdenum-based heterogeneous catalysts immobilized on dendrimer-functionalized graphene oxide via electrostatic interactions (Mo-1) or covalent bonding (Mo-2) are reported. The catalysts show excellent catalysis in epoxidation of alkenes with high conversion, better selectivity and good recyclability. The characteristics were identified by SEM, TEM (EDS-mapping), FT-IR, XRD, and XPS. The cause of the difference between the two catalysts is supported by DFT calculations.

钼基复合物在树枝状聚合物官能化氧化石墨烯上的固定化及其对烯烃环氧化的催化活性
报道了通过静电相互作用 (Mo-1) 或共价键 (Mo-2) 固定在树枝状聚合物官能化氧化石墨烯上的两种新型钼基多相催化剂。该催化剂在烯烃环氧化反应中表现出优异的催化转化率、较好的选择性和良好的可回收性。通过SEM、TEM（EDS-mapping）、FT-IR、XRD和XPS确定特征。DFT 计算支持了两种催化剂之间差异的原因。
