Figure 2From: A facile approach to prepare silicon-based Pt-Ag tubular dendritic nano-forests (tDNFs) for solar-light-enhanced methanol oxidation reaction The SEM images and EDS result of Ag DNFs. (a-d) The SEM images of typical Ag DNFs grown on plane silicon in 2.5 mM AgNO3 and 25% (v/v) buffered oxide etchant (BOE) for 300 s. (e) The EDS result of the Ag DNFs shown in (a).Back to article page
