Unique electronic properties arise when the size and shape of materials are reduced to the nanoscale. The changes in chemical and physical properties of nanoscale metals are even more pronounced when alloyed with other metals. In particular, we have designed well-defined and homogeneous bimetallic nanoparticles and studied their charge transfer properties. We have correlated the bimetallic nanoparticle's charge transfer properties with its catalytic efficiency. We further studied the bimetallic nanoparticle catalytic properties in the chemical conversion of organic acids and compared the results to their monometallic counterparts. We found that in several cases, the bimetallic nanoparticles exhibited improved selectivity and efficiency toward specific reactions. The electrochemical properties and catalytic behavior of the bimetallic metal nanoparticles will be presented.
