采用表面活性剂辅助自组装法，以结构导向剂十六烷基三甲基溴化铵（CTAB）和P123为催化剂，合成了介孔NiO催化剂。所得催化剂具有相似的化学组成，但不同的物理性质，包括介孔有序，表面积和孔径。将其用于油酸脱氧制十七烷的反应中。用P123合成的催化剂显示出最高的十七烷产率（63%），是商业NiO（19%）的性能的三倍。在脱氧反应期间观察到从NiO到Ni的相变。评价了用P123合成的催化剂的可循环性。
Mesoporous NiO catalysts were synthesized via surfactant assisted self-assembly employing structure directing agents CTAB and P123. The resultant catalysts had similar chemical composition but different physical properties including mesoporous ordering, surface area, and pore size. The mesoporous oxides were used as catalysts in the deoxygenation of oleic acid to heptadecane. The catalysts synthesized with P123 displayed the highest yields to heptadecane (63%) tripling the performance of commercial NiO (19%). A phase change from NiO to Ni was observed during the deoxygenation reaction. The recyclability of the catalyst synthesized with P123 was evaluated.
