Nano-Ru-based perovskites RGO are prepared simultaneously in presence of various A-metal salts (A = Sr, Ba or Ca salts) using two different methods for reaction initiation. No further calcination step is needed for the formation of well-defined perovskite structure. Graphene oxide (GO) is used as a fuel to prepare various Ru-based perovskites for the first time. The resulted low-Ru content nanocomposites are used as supercapacitor electrodes in a neutral electrolyte (1.0 M NaNO₃). The results show that the specific capacitance of the resulted nanocomposites strongly depends on the method of their preparation as well as the type of A-site of the nanocomposites. Ru-based perovskites RGO nanocomposites that are prepared by combustion method show higher specific capacitance than those prepared by microwave irradiation. The maximum specific capacitance of Sr-, Ba- and Ca-RG-C composites at scan rate 2 mV s⁻¹ are 564 (598 mF cm⁻²), 460 (487 mF cm⁻²) and 316 (336 mF cm⁻²) F g⁻¹, respectively. This value is higher than our previous work using a physical mixture between the individually prepared RGO and SrRuO₃. Lowest values for specific capacitance are obtained when using CaRuO₃/RGO prepared using microwave-assisted method (Ca-RG-M). The resulted A-RG-nanocomposites show very high cycling stability and good specific capacitance compared to other Ru-based structures previously reported in the literature. A correlation is defined between the structure and specific capacitance of the nanocomposites. It is confirmed that the nanocomposite size, morphology and distribution over the RGO matrix influence the supercapacitor characteristics.

 使用两种不同的反应引发方法，在各种A-金属盐（A = Sr，Ba或Ca盐）存在下，同时制备基于纳米钌的钙钛矿RGO 。无需进一步的煅烧步骤即可形成明确的钙钛矿结构。氧化石墨烯（GO）首次用作制备各种Ru基钙钛矿的燃料。所得的低Ru含量的纳米复合材料用作中性电解质（1.0 M NaNO ₃）中的超级电容器电极。结果表明，所得纳米复合材料的比电容在很大程度上取决于其制备方法以及A的类型。纳米复合材料的位置。通过燃烧方法制备的Ru基钙钛矿RGO纳米复合材料比通过微波照射制备的RGO纳米复合材料显示出更高的比电容。在扫描速率为2 mV小号Sr基，Ba基和Ca-RG-C复合材料的最大比电容^-1是564（598μF的厘米^-2），460（487μF的厘米^-2）和316（336μF的厘米^{- 2}）分别为F g ^-1。该值高于我们先前在单独制备的RGO和SrRuO ₃之间使用物理混合物的工作。当使用通过微波辅助方法（Ca-RG-M）制备的CaRuO ₃ / RGO时，可得到最低的比电容值。结果A与先前文献中报道的其他基于Ru的结构相比，-RG-纳米复合材料显示出非常高的循环稳定性和良好的比电容。在纳米复合材料的结构和比电容之间定义了相关性。证实了纳米复合材料的尺寸，形态和在RGO基质上的分布会影响超级电容器的特性。
