While significant cost reduction of green electricity from renewable sources has been achieved, technologies for storage and electrocatalytic conversion to transportable chemical fuels are needed for its on-demand use. At the same time, precious minerals and high process energy need to be avoided for sustainability and wide implementation of such technologies. We try to obtain novel redox active storage materials and electrocatalysts for water splitting by electrodeposition out of organic and abundant components. Cathodic electrodeposition from a mixture of Zn2+ and dihydroxy terephthalic acid (DHTPA) employing oxygen reduction reaction (ORR) yielded ZnO/DHTPA hybrid thin films in a porous structure to exhibit a reversible redox originating from DHTPA for storage devices, whereas anodic electropolymerization of amino-functionalized Neutral Red achieved a hydrogen-bonding conductive polymer catalyst (HCPC) for hydrogen evolution reaction in acidic media.
