Here we report the first membrane-free biofuel cell obtained using three-dimensional carbonaceous foam electrodes. We first developed a new synthetic pathway to produce a new carbonaceous foam electrode material bearing porosity both on the meso and macroporous scales. We proved that by increasing the porosity of our three-dimensional foams we could increase the current density of our modified electrodes. Then, by choosing the right combination of enzyme and mediator, and the right loading of active components, we achieved high current densities for an anodic system. Finally, we combined the improved cathode and anode to build a new membrane-free hybrid enzymatic biofuel cell consisting of a mediated anode and a mediator-free cathode.
在这里,我们报告了第一个使用三维碳泡沫电极获得的无膜生物燃料电池。我们首先开发了一种新的合成途径,以生产一种新的碳泡沫电极材料,该材料在中孔和大孔尺度上都具有多孔性。我们证明,通过增加我们的三维泡沫的孔隙率,我们可以增加改性电极的电流密度。然后,通过选择合适的酶和介体组合,以及合适的活性成分负载量,我们实现了阳极系统的高电流密度。最后,我们将改进的阴极和阳极组合起来,构建了一个由介体化阳极和无介体阴极组成的新型无膜混合酶生物燃料电池。
