Nanolayered Mn oxide/poly(4-vinylpyridine) as a model for Mn cluster in photosystem II was synthesized and characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FTIR) and UV-Visible spectroscopy (UV-Vis). The compound is a very efficient water oxidizing catalyst, and sizable oxygen evolution was detected at 50 mV overpotential at near neutral pH. The number is as low as the overpotential is used by nature in photosystem II of cyanobacteria, algae and green plants for similar reactions.
采用扫描电子显微镜（SEM）、透射电子显微镜（TEM）、动态光散射（DLS）、傅里叶变换红外光谱（FTIR）和紫外-可见光谱（UV-Vis）对纳米层状 Mn 氧化物/聚（4-乙烯基吡啶）进行了合成和表征，该化合物是一种非常有效的水氧化催化剂，在近中性 pH 下，在 50 mV 过电势下即可检测到大量氧气的产生。这一数值与蓝藻、藻类和绿色植物光合作用系统 II 中用于类似反应的过电势一样低。
