Three-dimensional carbonaceous electrodes with interconnected hierarchical porosity are prepared using Si(HIPE) exotemplating matrices, and are modified with glucose oxidase and Os polymer. The glucose electrooxidation current is 13-fold bigger on the porous electrode than on glassy carbon for the same enzyme loading. Therefore they are proposed for devices needing high current output, such as biofuel cells.
