锂离子电池在储能方面的广泛应用导致了一种新的废品流，其中含有丰富的有价值的金属锰、镍和钴，并具有众所周知的催化活性。在这项工作中，锂镍锰钴氧化物锂离子电池电极材料被证明是一种优秀的可重复使用的催化剂，用于将生物质衍生的呋喃醛和醇氧化成其增值的氧化产品，并在可持续聚合物工业中应用。废弃的Dell 1525笔记本电脑电池中的一种机械分离的组合正负极黑色材料在600°C的空气中热解，以去除粘结剂和电解液来制备催化剂。对催化剂进行了扫描电子显微镜、X射线荧光光谱和X射线晶体分析，结果表明催化剂中存在C、O、Li、Ni、Co和Mn等元素，表明在本研究所用的废旧锂离子电池中存在锂镍锰钴氧化物(LiNixMnyCozO2)类正极材料。该材料对呋喃-2-醛、5-羟甲基呋喃和5，5‘-[氧双(亚甲基)]双[2-呋喃]双[2-呋喃]醛中的醛和醇官能团的氧化反应是有效的，在120-140℃，1.24 Mpa氧气和0.10 MAQ条件下，产率为82-97%。Na2CO3中等浓度。
The wide use of Li-ion batteries in energy storage has resulted in a new waste product stream rich in valuable metals Mn, Ni, and Co with well-known catalytic activities. In this work, a spent Li-ion battery electrode material with lithium nickel manganese cobalt oxide is shown as an excellent reusable catalyst for oxidation of biomass-derived furan aldehydes and alcohols to their value-added oxidation products with applications in the sustainable polymer industry. A mechanically separated, combined cathode and anode black material from a spent DELL 1525 laptop battery was pyrolyzed in air at 600 °C to remove binders and electrolytes to prepare the catalyst. The SEM, XRF, and X-ray crystallography analysis of the catalyst showed the presence of C, O, Li, Ni, Co, and Mn, indicating the presence of a lithium nickel manganese cobalt oxide (LiNixMnyCozO2)-type cathode material in the spent Li-ion battery employed in the study. This material was shown as an efficient catalyst for the oxidation of aldehyde and alcohol functional groups in biofurans, furan-2-aldehyde, 5-hydroxymethyl furfural, and 5,5′-[oxybis(methylene)]bis[2-furaldehyde], to their corresponding carboxylic acids in 82–97% yield, at 120–140 °C, under 1.24 MPa oxygen, and in 0.10 M aq.
