氮化钼及其相关化合物已成为多种反应的催化剂。虽然氮化钼的掺杂具有较高的催化活性，但由于合成方法的限制，很难同时控制掺杂MoN的形貌、结晶度和掺杂状态。本研究以一种混合阴离子化合物NaMoO3F作为六方MoN相氮化钼的前驱体。与其他方法相比，这种方法使钴在氮化钼中的分布均匀。由于晶体中钴的高分布，从NaMoO3F中得到的钴掺杂氮化钼表现出较高的氧还原反应催化活性。本文提出，混合阴离子化合物可以作为其他材料的独特前体，以扩大材料的可控性，提高其活性。
Molybdenum nitrides and their related compounds have been focused as a catalyst for several reactions. Although the doping into molybdenum nitrides lead to the higher catalytic activity, the simultaneous control of the morphology, the crystallinity, and the dopant state in doped MoN cannot be easily achieved due to the limitation of the synthesis method. In this study, one of the mixed anion compounds, NaMoO3F was used as a precursor for molybdenum oxynitrides with hexagonal MoN phase. This route led to the homogeneous distribution of cobalt in the molybdenum oxynitride compared with that obtained by the other method. The cobalt‐doped molybdenum oxynitride from NaMoO3F exhibited high oxygen reduction reaction catalytic activity due to the high distribution of cobalt in the crystal. This paper proposes that the mixed anion compounds can be a unique precursor for the other materials to expand the controllability of materials toward improvement of their activity.
