氮掺杂石墨烯已成为钯在储氢和催化反应中的重要载体。碳材料（包括石墨烯、富勒烯和小碳簇）的分子轨道和负载的Pd物质的分子轨道将随着N掺杂剂的引入而更强地混合，这是由于界面处的静电吸引力增加。这增强了碳基底对负载的Pd的捕获力，防止其在许多实际应用中的浸出和聚集。由N掺杂的各种碳载体诱导的Pd纳米颗粒的更好的分散和稳定性令人满意，并且可以提高它们的效率并促进它们在几个领域的各种反应过程中的回收。
N-doped graphene has become an important support for Pd in both hydrogen storage and catalytic reactions. The molecular orbitals of carbon materials (including graphene, fullerene, and small carbon clusters) and those of the supported Pd species will hybrid much stronger as N dopants are introduced, owing to the increased electrostatic attraction at the interface. This enhances the carbon substrates' catching force for the supported Pd, preventing its leaching and aggregation in many practical applications. The better dispersion and stabilization of Pd nanoparticles, which are induced by various carbon supports with N-doping, are pleasing to us and could increase their efficiency and facilitate their recycling during various reaction processes in several fields.
