TEM images of a series of Au nanostructures/silica composites. Different morphologies and sizes is obtained by changing the reduction time. a 0 min, before the reduction reaction, displaying the Au precursor distributed homogenously in the ordered mesoporous silica matrix. b 2 min, showing the Au nanoparticles with a wide size distribution. c 8 min, the Au NPs show a structure of three-pods. d 15 min, the Au NPs with networked morphology has been formed. e-f 2 and 6 h, 3D mesoporous Au networks, the red arrows indicate that the Au NPs deposited within the same single mesostructural Ia3d domain of the original KIT-6. The scale bars in a, b, and cf are 100, 50, and 100 nm, respectively
