was then dissolved in an AZ developer (MicroChemicals – Germany), revealing the aluminium surface and the remaining resist was hard baked for 30 min at 55°C (Figure 2c). The exposed aluminium was then etched away by a wet etching process using an etchant solution (H 3PO 4:HNO 3:CH 3OOH:H 2O) for 2 minutes (Figure 2d).

Shape control in concave metal nanoparticles by etching ...

To describe the control by etching, we have reformulated the Wulff construction through the use of a geometric model that leads to concave polyhedra, which have a larger surface-to-volume ratio compared to that for nanocubes. Such an increase makes these sorts of nanoparticles excellent candidates to improve electrocatalytic performance.
