Abstract

The widespread use of Li-ion batteries (LIBs) in energy storage devices has resulted in the generation of additional waste which contains valuable metal ions and these metal ions are well known for their catalytic activities. The recovered black mass of cathode material was exposed to pretreatment with final calcination for 2 h at 800 ⁰C. After the calcination, the material was subjected to structural characterization (XRD, FE-SEM, EDAX, and XPS). In the present work, we have used spent LIBs cathode material as a catalyst for the oxidation reaction of benzyl alcohol to benzoic acid. The catalytic activity of this recovered cathode material was found to be highly efficient showing 100% conversion of benzyl alcohol with >99% selectivity of benzoic acid with lower catalyst loading of even 2%.

废锂离子电池正极材料作为苯甲醇氧化催化剂的性能检测

随着锂离子电池（LIB）在储能设备中的广泛使用，产生了含有宝贵金属离子的额外废物，而这些金属离子的催化活性是众所周知的。回收的黑色块状阴极材料经过预处理，最后在 800 0C 煅烧 2 小时。煅烧后，对材料进行结构表征（XRD、FE-SEM、EDAX 和 XPS）。在本研究中，我们将废 LIBs 阴极材料用作苯甲醇氧化成苯甲酸反应的催化剂。研究发现，这种回收的阴极材料具有很高的催化活性，在较低的催化剂负载量（甚至 2%）下，苯甲醇的转化率为 100%，苯甲酸的选择性为 99%。
