Abstract Nanocrystalline NiO with a coral-like structure (38 nm) has been prepared via thermal decomposition of a new precursor, nickel galactarate (NiC6H8O8·2H2O), at 500 °C for 3 h in air. Thermal decomposition of that precursor was studied by TG and DSC techniques. The resultant NiO was physicochemically characterized by XRD, FTIR, SEM, surface area, porosity and CO2-TPD. NiO was found to exhibit a remarkable activity towards the synthesis of MEK from 2-butanol between 200 and 325 °C. In addition, it has shown a great tendency to ease regeneration of the used catalyst after 192 h in stream by simple refreshing method.

来自半乳糖二酸镍二水合物的具有珊瑚状结构的分层纳米晶 NiO：一种用于生产甲乙酮的活性介孔催化剂

摘要 通过一种新的前驱体半乳二酸镍 (NiC6H8O8·2H2O) 在空气中 500 °C 下热分解 3 h，制备了具有珊瑚状结构 (38 nm) 的纳米晶 NiO。通过TG和DSC技术研究了该前体的热分解。通过XRD、FTIR、SEM、表面积、孔隙率和CO2-TPD对所得NiO进行物理化学表征。发现 NiO 在 200 到 325 °C 之间对由 2-丁醇合成 MEK 表现出显着的活性。此外，通过简单的更新方法，它显示出在流中 192 小时后易于再生使用过的催化剂的很大趋势。
