Özet:

 

Pd-Si-structured novel mesoporous nanocomposite catalytic  materials, having quite high Pd/Si ratios, were synthesized by an  acidic direct hydrothermal synthesis route.  The nanocomposite  catalytic materials were then characterized by XRD, XPS, EDS, nitrogen  adsorption, and SEM techniques.  Unlike MCM-41, the XRD patterns  indicated a rather wide d(100) band at a 2q value of about  1.9.  The materials, with very high Pd/Si wt ratios between 1.43 and  2.66, were synthesized and had BJH surface area values between 600 and  200 m2/g.  The pore size distributions of these materials were also  quite narrow, indicating pores between 2 and 7 nm.
