Electrochemical design of two-dimensional Au nanocone arrays using porous anodic alumina membranes with conical holes.
We report step-by-step electrochemical design of two-dimensional (2D) Au nanocone arrays by using novel porous anodic alumina membranes with conical holes. The cones with desirable aspect ratios can be fabricated by using the PAA templates with different aspect ratios. The Au nanocone arrays show high potentials as SERS (Surface Enhanced Raman Scattering)-active substrates and Au electrodes with high surface area.
