“…On the other hand, catalyst support is considered as an important factor that influences its activity. Researchers have found that carbon materials can improve the activity and stability of the catalysts employed in fuel cells (Yoo et al, 2008;Bessel et al, 2001;Joo et al, 2006;Bang et al, 2007;Xu et al, 2008;Zhao et al, 2010;Serp et al, 2003;Dong et al, 2010). However, above methods have their inherent drawbacks, such as the pre-synthesis of nanoparticles of catalysts and the modification of both the carbon substrates and the nanoparticles to effectively immobilize the nanoparticles on the substrates.…”
