摘要：

(Figure Presented) Freestanding porous gold films with arrays of spherical pores or hollow spheres were fabricated photochemically. UV irradiation of a polystyrene-sphere (PS) colloidal crystal template floating on a solution containing HAuCl4 and Na2SO3 led to gold deposition, and then PS removal gave a spherical-pore array. Irradiating the shell/sphere structure upside-down on fresh precursor solution gave a hollow-sphere array after PS removal (see picture). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
