Preparation of λ-MnO_2 catalyst from spent LiMn_2O_4-based lithium-ion battery

ZHANG Weixin,MA Shichuang,YANG Zeheng,ZHOU Chenxu,WANG Qiang(School of Chemical Engineering,Hefei University of Technology,Hefei 230009,Anhui,China)  
Manganese oxide was obtained by selective chemical leaching of lithium ion out from the spent LiMn2O4 electrode materials and in-situ phase transformation.The prepared manganese oxide was characterized by X-ray power diffraction (XRD) and showed cubic λ-MnO2.The λ-MnO2 powder was found to be an effective catalyst for the synthesis of iso-amyl acetate from acetic acid and iso-amyl alcohol.The reaction results showed that when the leaching sulfuric acid concentration was 0.5 mol·L-1 and reaction time was 3 h,λ-MnO2 showed the best catalytic activity and excellent selectivity for esterification of iso-amyl acetate(yield 94.62%).
