were prepared by impregnating the milled RH with a silver nitrate solution followed by carbothermal reduction. The composition and morphology of the prepared catalysts were fully assessed by IR, AAS, ICP-MS, XPS, XRD and STEM techniques. This novel bio-genic silver-based catalysts showed excellent activity and remarkable selectivity in the hydrogenation of nitro groups in both aromatic and aliphatic substrates
制定可持续管理和农业废物价值化的战略是最重要的。考虑到这一点,我们报告了使用稻壳 (RH) 作为原料制备用于加氢反应的多相催化剂。通过用硝酸银溶液浸渍研磨过的 RH 然后进行碳热还原来制备催化剂。通过IR、AAS、ICP-MS、XPS、XRD和STEM技术对制备的催化剂的组成和形貌进行了全面评估。这种新型的生物银基催化剂在芳香族和脂肪族底物的硝基氢化中表现出优异的活性和显着的选择性,即使在卤素、羰基、硼酸酯或腈等反应性官能团存在的情况下也是如此。
