In conventional water electrolysis, OER is thermodynamically slow and higher potential is generally required to proceed at a rate that can justify the economics of the process. Moreover, oxygen is a low value commodity which further reduce the economic significance of water splitting. Cost of hydrogen production through water electrolysis is expected to decrease further as a consequence of decreasing renewable energy (solar and wind etc.) cost. A hybrid process of hydrogen and renewable chemical production is desired to reduce the fossil fuel consumption in energy and chemical industry. This can be accomplished by coupling hydrogen evolution reaction (HER) during electrolysis of water and biomass oxidation as a replacement of traditional oxygen evolution reaction (OER). Production from hydrogen evolution reaction (HER) through water electrolysis and renewable chemical production through oxidation of biomolecules instead of traditional oxygen evolution reaction (OER) can not only help to produce hydrogen production cost but will produce renewable chemicals as well. Various promising bio-derived molecules are available and can be utilized on anodic side for their oxidation to chemicals. Among them HMF is a promising building block chemical. It is being produced by catalytic dehydration of cellulose. Cellulose is the main component of biomass. HMF produced a diverse range of chemicals that are a raw material for polymer, pharmaceutical and other chemical industries. Among various oxidation product of HMF, FDCA is a highly sought product. FDCA will replace terephthalic acid used in PET manufacturing for synthesis of a new class of biodegradable plastic PEF. PEF has superior mechanical and gas permeation properties compared to PET. Conventionally, oxidation of HMF is accomplished using heterogeneous catalyst at higher temperature and pressure in the presence of an oxidant. Due to severe conditions and cost of oxidants, electrocatalytic oxidation of HMF is proposed. This project will be focused on the synthesis of novel di- and tri-metal electrodes for electrochemical oxidation of HMF to FDCA at a wide range of pH under a different temperature range of (25~60) to investigate the conversion yield and reaction mechanism.
