AB  - Preparation of PdO/SiO(2)@graphene oxide (GO) hybrid aerogels were carried out 
      sol-gel method combined with atmospheric drying technology to study their 
      adsorption performance for thiophenics and compared with PdO/SiO(2). Scanning 
      electron microscope (SEM), N(2) adsorption-desorption isotherms, X-ray 
      diffraction (XRD) analysis, X-ray photoelectron spectroscopy (XPS), and fourier 
      transformation infrared spectroscopy (FT-IR) for samples were performed. The 
      adsorption performance of PdO/SiO(2)@GO for thiophene were better than that of 
      PdO/SiO(2), attributed to that incorporation of GO increased the specific surface 
      area and the Pd incorporation rate, where Pd(2+) ions acted as the pi-complexation 
      and sulfur-metal (SM) bond adsorption active centers, as well as GO adsorbed 
      thiophene by the pi-pi stacking effect. The adsorption capacities of 
      PdO/SiO(2)@GO-1.0 for thiophene (TH), benzothiophene (BT) and dibenzothiophene 
      (DBT) were 8.89, 9.3 and 12.6 mg-S/g(ads), respectively. The addition of GO in 
      aerogels could improve the inhibition effect of toluene, cyclohexene and pyridine 
      while decreased the inhibition effect of MTBE and H(2)O for the adsorption of 
      thiophene, due to the pi-pi stacking effect and the hydrophobicity of GO, 
      respectively. The adsorption process was spontaneous and exothermic, be well 
      fitted by the apparent second-order kinetic model and dominated by chemical 
      interaction. Pd/SiO(2)@GO-1.0 had a good solvent elution regeneration 
      performance.
