As one type of promising candidates for environmental and energy-related systems, multi-shelled transition metal oxide hollow structures （MS-TMOHSs） have drawn great scientific and technical interest in the past few years. This article highlights recent advances in one-pot solution synthesis of MS- TMOHSs. We begin it with an overview of synthetic strategies that have been exploited to achieve these peculiar structures. We then focus on one-pot solution approaches in the following four sections： i） soft templates directed growth; ii） Ostwald ripening; iii） controlled etching; and iv） gas bubble assisted growth. After giving a brief discussion on the unique properties and applications of these multi-shelled hollow structures, we conclude this review with the general challenges and the potential future directions of this excitin~ area of research.
