本硏究於超臨界二氧化碳環境下合成鈀金/石墨烯(PdAu/graphene)奈米複合材料，並應 用於非酵素型葡萄糖感測器。藉由超臨界流體的低黏滯性及高擴散性等特性，能將鈀金奈 米顆粒均勻地被覆在石墨烯上，所合成的鈀金奈米顆粒約爲5 rnn。硏究中也使用超臨界流 體技術合成金/石墨烯(Au/graphene)及鈀/石墨烯(Pd/graphene)作爲對照組。作爲偵測葡萄糖 的電極，鈀金/石墨烯有低於金/石墨烯的氧化電位，高於鈀/石墨烯的氧化電流。爲了進一 步提升感測性質，另外設計添加離子液體1-Butyl-l-Methylpyrrolidinium Bis (trifluoromethylsulfonyl) imide (BMP-NTF2)於感測電極中，使其感測靈每夂度獲得顯著提升。

In this study, we synthesize PdAu/graphene nanocomposites by supercritical carbon dioxide (scC02) for non-enzymatic glucose detection. With the aid of scC02, which has gas-like diffusivity, extremely low viscosity, and near-zero surface tension, the synthesized nano-sized PdAu particles (approximately 5 nm in diameter) are uniformly distributed on graphene. For comparison, Pd/graphene and Au/graphene are both synthesized using the same process. The PdAu/graphene electrode shows higher cuiTent density than Pd/graphene and lower oxidation potential than Au/graphene in detecting glucose. With the incorporation of 1-Butyl-1-Methylpyrrolidinium Bis(trifluoromethylsulfonyl)imide (BMP-NTf2) ionic liquid in PdAu/graphene electi'ode, the detection sensitivity significantly improved.
