Outline of Final Research Achievements

Shape-control of gold crystals is important because their properties strongly depend on the structures and the sizes. In this work, anisotropic-re-shaping of gold crystals are investigated for the sustainable use of the catalytic applications.
First, micro-sized tabular gold crystals were prepared by reduction of HAuCl4 in the presence of a long chain amidoamine derivative. Reshaping of the gold crystals was approached by adding CTAB/HAuCl4 mixture. At the initial stage, the tabular crystals were etched by Br- and were changed into granular crystals. In the later stage, however, the etched crystals were reshaped into rod crystals having {211} and {110} facets due to surface selective adsorption of CTAB micelles. The rod crystals grew along the <111> direction. AFM and SAED observation revealed that anisotropic growth was caused by the changes in stabilities of gold crystal facets using the surfactant.
