Abstract

The essential ideal electrode is at core of (photo)electrochemical energy conversion and storage devices. It is a great challenge to design self-standing electrodes as electrochemical micro-reactors, especially with respect to cost reduction and ease of fabrication. Natural wood possesses a unique channel network, exhibiting an anisotropic hierarchical architecture, which is a suitable and excellent candidate for hosting catalysts in integrated electrodes. This unique capillary-based host matrix provides ample opportunity for nanostructural tailoring to achieve catalyst nucleation and presentation. In addition, graphitic carbonized wood (CW) provides an excellent path for electron transport, with an established high electronic conductivity. We can calculate electron catalysis mechanism.
