Porous, hollow metal carbonate microstructures show many unique properties, and are attractive for various applications. Herein, we report the first demonstration of a general strategy to synthesize hollow metal carbonate structures, including porous MnCO 3 hollow cubics, porous CoCO 3 hollow rhombuses and porous CaCO 3 hollow capsules. For example, the porous, hollow MnCO 3 microcubes show larger Brunauer–Emmett–Teller (BET) surface areas of 359.5 m 2 g −1 , which is much larger than that of solid MnCO 3 microcubics (i.e., 12.03 m 2 g −1 ). As a proof of concept, these porous MnCO 3 hollow microcubes were applied to water treatment and exhibited an excellent ability to remove organic pollutants in waste water owing to their hollow structure and large specific surface area.
