Manganese oxide materials are attractive due to their applicability in areas such as ion‐exchange, catalysis, heavy metal ion adsorption, and energy storage in batteries and supercapacitors. Shanshan Wu and Fencun Xie (article no. 1900081) have synthesized four kinds of hydrous manganese dioxide (HMO) with different morphologies by a one‐pot method. The effect of KMnO₄ on the structure and adsorption behavior of HMO has been thoroughly investigated. Higher concentration of KMnO₄ leads to a disordered, lower‐crystallinity structure, and higher zeta potential of HMO. The addition of KMnO₄ after reaction can also affect the structure and adsorption behavior of HMO, leading to higher crystallinity, fewer lattice defects, and higher adsorption capacity. The SEM and TEM analyses reveal different steps of the HMO formation process.

水合二氧化锰：KMnO4对水合二氧化锰对Pb（II）和Cd（II）的结构和吸附行为的影响（晶体研究与技术9/2019）

氧化锰材料因其在离子交换，催化，重金属离子吸附以及电池和超级电容器中的能量存储等领域的适用性而具有吸引力。吴珊珊和谢芬存（文章号1900081）通过一锅法合成了四种不同形态的含水二氧化锰（HMO）。彻底研究了KMnO ₄对HMO的结构和吸附行为的影响。较高浓度的KMnO ₄会导致无序的低结晶度结构和较高的HMOζ电位。添加KMnO ₄反应后还会影响HMO的结构和吸附行为，导致更高的结晶度，更少的晶格缺陷和更高的吸附能力。SEM和TEM分析揭示了HMO形成过程的不同步骤。
