Latar Belakang
• Pt masih merupakan CE terbaik sampai saat ini• Hanya Pt, logam mulia, harganya mahal• Perlu pengembangan CE lain yang low-cost
material, tetapi well-performed
Beberapa material berbasis karbon yang sudah dikembangkan
• Graphene Supported Platinum Nanoparticle, Ƞ=2,91%, Pt=2,11% (Bajpai, R.; Roy, S.; Kumar, P.; Bajpai, P. :2011)
• Multi-Wall Carbon Nanotube Hybrid, Ƞ=7,36%, Pt=7,54% (W, J.; Yue, G.; Xiao, Y.; Huang, M.; 2012)
• Graphene Quantum-Dot-Doped Polypyrrole, Ƞ=5,27%, Pt=6,2% (Chen, L.; Guo, C.X.; Zhang, Q.; Lei, Y. :2013)
• Reduced Graphene Oxide−TaON Composite , Ƞ=7,65%, Pt=7,91% (Li, Y.; Wang, H.; Feng, Q.; Zhou, G. : 2013)
• Nitrogen-Doped TiO2/Graphene Nanohybrids , Ƞ=5,04, Pt=6,4% (Wang, R.; Wu, Q.; Lu, Y.; Liu, H.; Xia, Y.; Liu, J.; Yang, D. :2012)
• Catalytic Multiwall Carbon Nanotube , Ƞ= 7,67%, Pt=8,03% (Lee, J.W.; Ramasamy, E.; Lee, D.Y.; Song, J.S.: 2009)
• Vertically Aligned Single-Walled Carbon Nanotubes, , Pt=5,6% (Dong, P.; Pint, C.L.; Hainey, M.; 2011)
• Sub-micrometer-sized Graphite, Ƞ= 6,2 %, Pt=5,6% (Veerappan, G; Bojan, K.; Rhee, S.W.; 2011)
