A visible difference : SnO 2 nanorods and V‐shaped bipods with small diameters (<5 nm; see TEM image), high crystallinity, and good solubility in organic solvents have been synthesized. The bipods have high structural stability and a photocatalytic activity driven by visible rather than UV light. Electrodes based on the bipods have unique photoelectrochemical and electronic properties.
