对生物质加工非贵金属催化剂的研究发现，废锂离子电池的热解电极涂层可以作为d -葡萄糖氧化成乙醇酸的优良催化剂。以DELL 1525笔记本电脑废旧电池为原料，在600℃下对18650个锂离子电池的黑色电极涂层进行热解，制备了新型无/低成本催化剂。用SEM、EDX和x射线对催化剂进行了表征，结果表明，催化剂碳上含有锂镍锰钴氧化物（lianibmmccodoe）， Ni: Mn: Co: 4.12: 2.10: 1.50。考察了该材料在aq. NaOH和水中氧化d -葡萄糖的催化活性；乙醇酸、酒石酸、苹果酸、琥珀酸和2-羟基丁酸是主要的降解产物。在3.4 Atm条件下，d -葡萄糖氧化乙醇酸收率最高，达94%。氧，120°C, 2.0 h，在0.5 M aq. NaOH中使用10 g催化剂/mol葡萄糖。
A search for non-noble catalysts for biomass processing led to the discovery that pyrolyzed electrode coating of spent Li-ion batteries can be used as an excellent catalyst for oxidation ofD-glucose to glycolic acid. New no/low-cost catalyst was prepared by pyrolyzing black electrode coatings of 18,650 Li-ion cells from a spent DELL 1525 laptop battery at 600 ºC. Catalyst was characterized using SEM, EDX and X-ray and was shown to contain lithium nickel manganese cobalt oxide (LiaNibMncCodOe) on carbon with Ni: Mn: Co 4.12: 2.10: 1.50. The catalytic activity of this material was evaluated for oxidation ofD-glucose in aq. NaOH and water; glycolic, tartaric, malic, succinic and 2-hydroxybutaric acid were identified as key degradation products. The highest glycolic acid yield of 94% was obtained for oxidation ofD-glucose under 3.4 Atm. oxygen, 120 °C, 2.0 h in 0.5 M aq. NaOH using 10 g catalyst/mol glucose.
