Surface Chemistry of Mixed-metal Systems

چکیده
Interest in bimetallic catalysts has risen steadily over the years because of the commercial success of these systems [1]. This success results from an enhanced ability to control the catalytic activity and selectivity by tailoring the catalyst composition [2,3]. A long-standing question regarding such bimetallic systems is the nature of the properties of the mixed metal system which give rise to its enhanced catalytic performance relative to either of its individual metal components. These enhanced properties (improved stability, selectivity and/or activity) can be accounted for by one or more of several possibilities.
