The electrochemical oxidation of glycerol (GOR) is gaining traction as a sustainable method to convert biodiesel byproducts into valuable chemicals and fuels, aligning with global demands for renewable energy and green production. Recent advances in catalyst design, reaction mechanisms, and system integration are driving progress, though challenges in selectivity, stability, and scalability remain pivotal for industrial adoption. Researchers are tuning both noble and non-noble metal catalysts—through methods such as facet engineering and single-atom doping—to selectively steer reactions toward high-value multi-carbon products. Furthermore, coupling GOR with cathodic processes like hydrogen evolution or CO₂ reduction offers a path to lower energy use and co-produce clean fuels. Key hurdles, including mass transfer limits and feedstock compatibility, still need addressing. Proposed solutions range from advanced electrode assemblies to integrated techno-economic assessments. Moving forward, a system-level approach that balances technical performance with economic viability will be essential to accelerate GOR technology toward real-world application.
