Abstract:
We report a universal platform for the synthesis of monolithic porous gold materials with hierarchical bicontinuous morphology and combined macro- and mesoporosity using a synergistic combination of nanocasting and chemical dealloying. This robust and accessible approach offers a new design paradigm for the parallel optimization of active surface area and mass transport in porous metal electrodes.
