Abstract

Grafina oksida tereduksi (rGO) dibuat dengan metode Hummer termodifikasi dan direduksi menggunakan vitamin C. Porous rGO disintesis melalui aktivasi dengan KOH menggunakan tubular furnace dalam keadaan inert. Hasil pengujian menunjukkan bahwa porous rGO/CuO memiliki kemampuan reduksi paling tinggi dibuktikan dengan nilai ECSA sebesar 0,440 cm2 yang menunjukkan situs aktif yang tinggi, aktivitas elektrokatalitik yang besar ditunjukkan dengan nilai Rct sebesar 25,3 Ω, dan memiliki sifat yang stabil dalam potensial -0,4 hingga -1 V vs RHE selama 17 jam.

Reduced graphene oxide (rGO) was prepared using a modified Hummer's method and reduced using vitamin C. Porous rGO was synthesized through activation with KOH using a tubular furnace in an inert atmosphere. The test results shows that porous rGO/CuO has the highest reduction capacity, as evidenced by an ECSA value of 0.440 cm², indicating a high number of active sites, a large electrocatalytic activity, as evidenced by an Rct value of 25.3 Ω, and stable properties in the potential range of -0,4 to -1 V vs RHE for 17 hours.
