Thermally reduced graphite oxide and titanium dioxide (TRGO-TiO₂) composite is synthesized by using a simple chemical method for supercapacitor applications. The TRGO-TiO₂ composites have higher capacitance than that of each precursor, such as GO, TRGO, and TiO₂. Electrochemical performance of the composites with different weight ratio of TRGO to TiO₂ is also investigated, and optimal ratio for the best performance is 7 to 3, resulting in the specific capacitance of 380 Fg^-1. The best performance of the TRGO-TiO₂ composite is attributed to synergic effect of the high electrical conductivity supported by TRGO and electroactive property of TiO₂.

通过使用简单的化学方法，将热还原的氧化石墨和二氧化钛（TRGO-TiO ₂）复合材料合成为超级电容器。TRGO-TiO ₂复合材料的电容量高于GO，TRGO和TiO ₂等每种前体的电容量。还研究了不同重量比的TRGO与TiO ₂的复合材料的电化学性能，最佳性能的最佳比例为7：3，比电容为380 Fg ^-1。TRGO-TiO ₂复合材料的最佳性能归因于TRGO支持的高电导率和TiO _2的电活性的协同效应。
