Variation in the extent of annealing of a TiO2(110) surface was used to control the distribution of deposited Pd, Au, and Pd - Au clusters at room temperature. Programming with respect to the metal deposition and thermal sintering was used to optimize the size distribution and cluster density of Pd - Au mixed-metal clusters. The influence of varying the evaporation sequence on the cluster distribution is demonstrated, and the results explained using known sintering mechanisms.
