The catalytic behavior of platinum nanoparticles modified by iron (III) ions and 1-Butanethiol (cas 109-79-5) was evaluated by determining the selectivity of hydrogenation of trans,trans-2,4-hexadienal, where the hydrogenation products were monitored by UV–vis spectroscopy and gas chromatograph. For the pure platinum nanoparticles, the selectivity to trans,trans-2,4-hexadienal is less than 5%; while for platinum nanoparticles modified by iron (III) ions and 1-butanethiol, the selectivity increased to 78% with a conversion of 86.5%. The enhancement in the selectivity of the reaction can be attributed to the synergic effects of iron (III) and 1-butanethiol.
