Incorporation of Pd Monometallic Nanoparticles into Modified SBA-15 with Dual Stimuli Responsive PDMAEMA and their Catalytic Applications |
| 초록 |
Nitroaromatic compounds are highly toxic and environmental contaminant. It can be reduced to less toxic and environmental friendly product such as 4-aminophenol and o-phenylenediamine etc. by using sodium borohydride as reducing agent. A method of grafting pH and temperature responsive poly (N, N-dimethylaminoethyl methacrylate) (PDMAEMA) on the surface of well-defined hexagonal mesoporous SBA-15 via free radical polymerization was adopted. Further, Pd monometallic nanoparticle was incorporated over the surface of pre-synthesized SBA-15/PDMAEMA catalyst. The present catalyst shows responsive behaviour during the reduction of nitro compounds by varying pH and temperature. The purpose of this study is to examine the structure, morphology and the dual responsive property of PDMAEMA coated SBA-15 and the surface can be decorated by other monometallic nanoparticle which further can act as catalyst for various catalytic and environmental applications. |
