摘要: Ru super(0)-nanoparticles of approximately 5 nm size were generated by incipient impregnation of RuCl sub(3) into the nanopores of the acid activated Montmorillonite clay followed by polyol reduction. Acid activation of the clay increases the surface area by generating nanopores (0-10 nm), which act as a host and stabilize nanoparticles in the pores. The generated Ru super(0)-nanoparticles exhibit inter-planar lattice fringe spacing of 0.21 nm of the face centered cubic lattice of Ru super(0) crystals, and show efficient catalytic activity in the chemoselective transfer hydrogenation reduction of substituted nitrobenzenes to corresponding anilines with high yield of conversion (56-97%) and selectivity (91-100%) depending upon the nature of the substituents. The reactions were carried out in the presence of isopropanol, which served as the solvent as well as the reductant. The catalysts were found to be active for several catalytic runs. 出版日期: 2012-04-01 出處: Green chemistry : an international journal and green chemistry resource : GC, 2012-04, Vol.14 (4), p.1086-1093 資源來源: Royal Society of Chemistry 識別號: ISSN: 1463-9262 識別號: EISSN: 1463-9270 識別號: DOI: 10.1039/c2gc16441h
