Abstract A cost-effective preparation method is proposed to prepare nanoporous alumina (NA) using aluminum chloride as a precursor with a lower cost than aluminum butoxide. In addition, the surfactant template was replaced with magnesium stearate, which has a lower unit cost in stearate acid. The adsorption isotherm test for the CO gas was carried out to compare the adsorption performance of the NA adsorbents prepared using post-hydrolysis (NA) and cost-effective precipitation (C-NA). In addition, C-NA exhibited a similar uptake capacity as NA, and the maximum uptake capacity of Pd/C-NA increased 1.3 times via Pd nanodots loading.

CO吸附剂沉淀模板法制备氯化铝纳米多孔氧化铝

摘要 提出了一种以氯化铝为前驱体制备纳米多孔氧化铝（NA）的低成本制备方法，其成本低于丁醇铝。此外，表面活性剂模板被硬脂酸镁替代，在硬脂酸中具有较低的单位成本。对 CO 气体进行吸附等温线测试，以比较使用后水解 (NA) 和成本效益沉淀 (C-NA) 制备的 NA 吸附剂的吸附性能。此外，C-NA 表现出与 NA 相似的吸收能力，通过负载 Pd 纳米点，Pd/C-NA 的最大吸收能力增加了 1.3 倍。
