The extraction, processing, and utilization of petroleum often results in the release of diverse hydrocarbon pollutants into the environment, leading to severe ecological and health implications. Herein, the adsorption and separation of ethane (EAN), ethene (EEN), ethyne (EYN), and benzene (BZN) fractions of paraffin, olefin, acetylene, and aromatic petroleum hydrocarbons were investigated via the catalytically engineered nickel group transition metals; nickel (Ni), palladium (Pd), and platinum (Pt). These transition metals were coordinated on Germanium-doped graphitic carbon nitride (Ge@g-CN) nanostructures, and the behavior of the systems was studied through Kohn-Sham density functional theory (KS-DFT) with the B3LYP-D3(BJ)/Def2-SVP computational method. The adsorption of petroleum hydrocarbons decreased in the order Ge_Ni@CN > Ge_Pd@CN > Ge_Pt@CNGe_Pt@CN. These results showed that the coordination of Ni, Pd, and Pt within Ge@CN improved the separation of petroleum hydrocarbons.
石油的开采、加工和利用常常导致各种碳氢化合物污染物释放到环境中，从而产生严重的生态和健康问题。在此，通过催化工程化的镍族过渡金属（镍（Ni）、钯（Pd）和铂（Pt））对石蜡、烯烃、乙炔和芳烃石油烃中的乙烷（EAN）、乙烯（EEN）、乙炔（EYN）和苯（BZN）馏分进行了吸附和分离研究。这些过渡金属负载于锗掺杂的石墨相氮化碳（Ge@g-CN）纳米结构上，并采用B3LYP-D3(BJ)/Def2-SVP计算方法，通过Kohn-Sham密度泛函理论（KS-DFT）研究了该体系的行为。石油烃的吸附量顺序为Ge_Ni@CN > Ge_Pd@CN > Ge_Pt@CNGe_Pt@CN。这些结果表明，Ni、Pd和Pt在Ge@CN中的配位作用改善了石油烃的分离效果。
