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.

通过在空气中在500°C下热分解一种新的前驱体半乳糖酸镍（NiC ₆ H ₈ O ₈ ·2H ₂ O）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CO ₂ -TPD对所得的NiO进行物理化学表征。发现NiO在200至325°C的温度下对由2-丁醇合成MEK表现出显着的活性。另外，已经显示出很大的趋势，即通过简单的刷新方法在流过192小时后易于使用过的催化剂再生。
