Transition metal oxides (TMOs) consist of a series of solid materials, exhibiting a wide variety of structures with tunability and versatile physicochemical properties. Such a statement is undeniably true for chiral TMOs since the introduction of chirality brings in not only active optical activities but also geometrical anisotropy due to the symmetry-breaking effect. Although progressive investigations have been made for accurately controlled synthesis and relevant explanations on the chirality origin of such materials, the overall field of chiral TMOs is still in its infancy with adequate space for interdisciplinary communications and development. Herein, therefore, recent advances in both experimental phenomena and theoretical calculations in this area are reviewed, to elucidate the underlying chiral origin with respect to their fabrications process, triggering new insights for further evolution of this field.
过渡金属氧化物（TMOs）由一系列固体材料组成，呈现出各种各样具有可调性和多样物理化学性质的结构。对于手性过渡金属氧化物而言，这样的描述无疑是正确的，因为手性的引入不仅带来了活跃的光学活性，还由于对称破缺效应产生了几何各向异性。尽管已经对手性过渡金属氧化物进行了精确控制合成以及关于此类材料手性起源的相关解释的深入研究，但手性过渡金属氧化物的整个领域仍处于起步阶段 , 仍有足够的空间进行跨学科交流与发展。因此，本文综述了该领域在实验现象和理论计算方面的最新进展，以阐明其制备过程中潜在的手性起源，为该领域的进一步发展引发新的见解。
