Research on developing electrodes from abundant resources for electrochemical organic synthesis is conducted. By converting cellulose into electrically conductive textiles, silver-coated tin electrodeposition and alloying are achieved for efficient synthesis of organic compounds.
The development of electrodes (for sensors, energy technologies, and electrosynthesis) from abundant resources is necessary as a contribution to sustainability. Cellulose, the most abundant polymer, offers robust substrates for metalization towards the electrode development for electrosynthesis of organic chemicals. Electroless and electrodeposition methods are used to convert non-conductive cellulose-based textiles into electrically conductive textiles. The effect of current density on the electrodeposition of Sn onto a silver-coated textile is shown here to lead to Ag-Sn alloy and Sn deposits. The prepared Sn-Ag-VF textile electrode was investigated for electrifying the organic synthesis of homoallylic alcohol using benzaldehyde and allyl bromide as a model reaction. The homoallylic alcohol is synthesized in an undivided cell in the millimolar scale via constant current electrolysis method with 86 % conversion efficiency and up to a maximum of 72 % current efficiency.
