A porous trimetallic Au@Pd@Ru nanoparticle system: Synthesis, characterisation and efficient dye degradation and removal

A facile room temperature one-pot synthesis of trimetallic porous Au@Pd@Ru nanoparticles (Au@Pd@RuNPs) has been developed. The trimetallic nanoparticles have been prepared by the successive sacrificial oxidation of cobalt nanoparticles (CoNPs). The average particle size of Au@Pd@RuNPs is 110 nm. The porous nature and the presence of Au, Pd and Ru have been confirmed via TEM, FE-SEM and EDS analyses. The trimetallic nanoparticles have shown excellent catalytic activity towards the reduction of p-nitrophenol and efficient degradation of various azo dyes. This has been further extended towards the removal of colour from waste water via the catalytic degradation of azo dyes. Moreover, the produced amine can be eliminated from the waste water via its sorption on an industrial solid waste dolochar.

Hydrogenation of ortho-substituted nitrobenzenes over palladium catalysts

Hydrogenation of o-nitrobenzenes, under mild conditions (1 atm of hydrogen, 20-40°C, organic solvents) over a Pd/C catalyst and the palladium-containing anion exchangers AN-1 and AV-17-8 proceeds without the formation of intermediate products. The yield of primary amines varies from 25 to 100%. It was shown that the palladium-containing anion exchangers are superior to Pd/C in selectivity and stability in the hydrogenation of o-nitrobenzenes. Based on quantum-chemical calculations of substrate molecules, a two-parameter correlation was proposed to describe the electronic and steric effects of the substituent on the hydrogenation rate.
