摘要
SWNTs/Pt composites for catalysis were prepared through redox reaction between SWNTs and K2PtCl6. Characterization of the composites by TEM, XPS and TG techniques revealed that large quantities of Pt particles with diameters of similar to 1.5 nm distribute evenly on the SWNTs. The influences of concentration of K2PtCl6 solution and solvents of SWNTs on the quantity and size of Pt particles were investigated. SWNTs/Pt composites containing 24.76% (mass fraction) Pt were obtained using high purity SWNTs and K2PtCl6 solution of 10 mmol/L. The SWNTs/Pt composites exhibit high catalytic activity for hydrogenation of cyclohexene. The conversion rate from cyclohexene to cyclohexane is up to 100% at room temperature.
