二氧化锰的物理、化学性质与其电化学活性的相关(1)

The relation between chemical,physical properties and electrochemical activity for manganese dioxides(Ⅰ)

半个世纪以来,为了预言二氧化锰样品的电化学活性,研究了很多二氧化锰的化学性质(如化学组成、亲和势等)和物理性质(如晶体结构、晶胞参数、表面积、表面OH基、表面极性、表面形态、表面结构、密度、粒度分布、水含量和结合水、分解温度、磁化率、电导率、质子扩散系数、电位、pH、等吸附点和等电位、离子吸附和离子交换、硬度、反射系数等)与电化学活性的相关性,让我们了解到如何快速地选择二氧化锰样品。

For a half century, in order to predict the electrochemical activity for manganese dioxides, the relationship between the chemical properties （chemical composition, affinity）, physical properties （crystal structure, crystal parameters, surface area, surface OH group, surface polarization, surface morphology, surface structure, density, distribution of particle, water content and combine water, decomposition temperature, magnetic susceptibility, conductivity, proton diffusion coefficient, potential, pH, adsorption point and electric point, ion adsorption and ion exchange properties, hardness, reflection factors） and electrochemical activity for manganese dioxides was studied. These would lead us to have a better understanding to quickly select the manganese dioxides samples.
