采用统计实验设计方法确定了制备负载氧化锰的活性炭基质的显著因素。以高锰酸钾与碳材料反应制备的碳基体为氧还原气体扩散电极，研究了氧还原气体扩散电极的性能。采用二水平全因子试验设计，考察了KMnO4浓度、反应温度和反应时间三个因素的影响。讨论了炭的形态改变及其对氧还原性能的影响。温度、KMnO4浓度以及温度与反应时间的交互作用对锰氧化物负载碳电极的催化活性有显著影响。
The statistical design-of-experiment method was used to identify the significant factors for making a manganese oxide-loaded activated carbon matrix. The carbon matrixes, which were made by reacting KMnO4with carbon material, were tested as gas-diffusion electrodes for oxygen reduction. Three factors—KMnO4concentration, reaction temperature, and reaction duration were tested in a two-level full-factorial design-of-experiment. The modification of carbon morphology and its effect on the performance of oxygen reduction are discussed. Temperature, KMnO4concentration, and the interaction between temperature and reaction time were found to have a significant influence on the catalytic activity of the manganese oxide-loaded carbon electrode.
