I synthesize Cu nanoparticles (d<30nm) deposit them on y-Al2O3 support and verify their structure and composition using HRTEM imagery XRD CO chemisorption and H2-TPR. I then add low concentrations of Pd using a sonication method and verify uptake and alloying with UV-vis and XPS. Finally I demonstrate the improved ability of the catalyst to selectively hydrogenate phenylacetylene to styrene compared ... read moreto similar metal loadings of Pd catalysts particularly at high conversion."read less
