Global production of biodiesel is increasing remarkably. In 2021, its production surpassed 50 billion
liters and resulting in the generation of 5 billion liters of glycerol. The rapid expansion of the biodiesel
industry has resulted in an excess supply of glycerol worldwide. Therefore, it is imperative to explore
innovative and cost-effective methods for upgrading crude glycerol. This study focuses on the
electrocatalytic reduction (ECR) of glycerol into valuable chemicals using a simple cell. The
experiments were conducted under controlled operating parameters, utilizing different types of
working electrodes such as platinum (Pt) and carbon (C) at a constant room temperature of 25 °C.
The findings demonstrated that as the reaction time increased, the conversion of glycerol also
increased which indicates that the conversion is time dependent. After 24 hours of reaction, the
highest glycerol conversion rate achieved was 41.06% with the C cathode, while the Pt cathode
achieved a conversion rate of 31.03%. The superior efficiency of the C cathode over the Pt cathode
can be attributed to its larger active surface area and higher hydrogen evolution reaction (HER)
overpotentials. As a result, the C cathode exhibits promising potential as a low-cost electrocatalyst
for glycerol deoxygenation reactions.
