In this paper, the first bio-nano colloid including manganese oxide nanoparticles and copper nanocomplex in the presence of Amaranthus spinosus as one unwanted plant was prepared (Mn3O4/CuL bio-nanocolloid). As-prepared bio nanocolloid was analysed completely by different techniques such as FT-IR, ICP-AES, SEM, EDX, TEM and elemental analysis to have the size, structure, morphology and elements in this compound. This bio-nanocolloid showed high catalytic activity towards green oxidation reactions of alcohols using hydrogen peroxide under solvent free conditions. The longevity, easy and practical recoverability of the solid catalyst was also confirmed for six times. The natural starting material for a long-term stability catalyst preparation, using ideal oxidant (H2O2), solventless and easy work up show the great potential in scalability for actual industries applications.

第一种廉价的希夫碱/氧化锰铜生物纳米复合材料，来自有害植物，是一种强大的工业催化剂。

在本文中，制备了第一个生物纳米胶体，其中包括锰氧化物纳米颗粒和铜纳米络合物，在A菜作为不想要的植物存在下（Mn3O4 / CuL生物纳米胶体）。使用不同的技术（例如FT-IR，ICP-AES，SEM，EDX，TEM和元素分析）对制得的生物纳米胶体进行完全分析，以了解该化合物的大小，结构，形态和元素。这种生物纳米胶体在无溶剂条件下使用过氧化氢对醇的绿色氧化反应显示出高催化活性。还证实了固体催化剂的寿命长，容易和实用的可回收性。使用理想的氧化剂（H2O2）作为长期稳定的催化剂制备的天然原料，
