Over the past decades, research efforts are being devoted into utilizing the biomass waste as a major source of green energy to maintain the economic, environmental, and social sustainability. Specifically, there is an emerging consensus on the significance of glycerol (an underutilised waste from biodiesel industry) as a cheap, non-toxic, and renewable source for valuable chemicals synthesis. There are numerous methods enacted to convert this glycerol waste to tartronic acid, mesoxalic acid, glyceraldehyde, dihydroxyacetone, oxalic acid and so on. Among these, the green electro-oxidation technique is one of the techniques that possesses potential for industrial application due to advantages such as non-toxicity process, fast response, and lower energy consumption. The current review covers the general understanding on commonly used techniques for alcohol (C₁ & C₂) conversion, with a specific insight on glycerol (C₃) electro-oxidation (GOR). Since catalysts are the backbone of chemical reaction, they are responsible for the overall economy prospect of any processes. To this end, a comprehensive review on catalysts, which include noble metals, non-noble metals, and non-metals anchored over various supports are incorporated in this review. Moreover, a fundamental insight into the development of future electrocatalysts for glycerol oxidation along with products analysis is also presented.

在过去的几十年中，研究工作致力于将生物质废物作为绿色能源的主要来源，以维持经济，环境和社会的可持续性。具体而言，人们对甘油（生物柴油行业未充分利用的废物）作为廉价，无毒且可再生的有价值的化学合成来源的重要性达成了共识。已经采取了许多方法来将这种甘油废料转化为酒石酸，中草酸，甘油醛，二羟基丙酮，草酸等。其中，绿色电氧化技术是无毒工艺，响应速度快，能耗低等优点，是具有工业应用潜力的技术之一。₁＆C ₂）转换，并特别了解甘油（C ₃）电氧化（GOR）。由于催化剂是化学反应的基础，因此它们对任何工艺的总体经济前景都有影响。为此，本篇综述对催化剂进行了全面的综述，其中包括贵金属，非贵金属和锚定在各种载体上的非金属。此外，还提供了对未来甘油氧化电催化剂的开发以及产品分析的基本见解。
