Output

Wood, a hierarchically porous and renewable biomaterial, is demonstrated here as a bifunctional electrode platform for both electrocatalytic CO2 reduction and electroanalytical sensing. The naturally aligned microchannels of wood facilitate efficient mass transport, enabling the activated wood electrode to achieve a CO2-to-formate current density of 53.8 mA cm^-2 with a Faradaic efficiency of 70.8% at -1.8 V versus Ag/AgCl. In electroanalytical mode, the wood electrode detects myricetin with a linear range of 0.01-150 uM and a detection limit of 3 nM, and cadmium (II) with a linear range of 0.01-50 uM, substantially outperforming conventional glassy carbon electrodes. These results establish wood as a versatile, sustainable electrode material that bridges electrocatalysis and electroanalysis.
