ferritin templated synthesis and self assembly of pt nanoparticles on a monolithic porous graphene network for electrocatalysis in fuel cells
ACS Applied Materials & Interfaces, 2013Co-Authors: Huajun Qiu, Xiaochen Dong, Barindra Sana, Tao Peng, David Paramelle, Peng Chen, Sierin LimAbstract:The monolithic three-dimensional (3D) graphene network is used as the support for Pt nanoparticles (NPs) to fabricate an advanced 3D graphene-based electrocatalyst. Distinct from previous strategies, the monodispersed Pt NPs with ultrafine particle size (∼3 nm) are synthesized using ferritin protein Nanocages as the template and subsequently self-assembled on the 3D graphene by leveraging on the hydrophobic interaction between the ferritin and the graphene. Following the self-assembly, the ferritins are removed, resulting in a stable Pt NP/3D graphene composite. The composite exhibits much enhanced electrocatalytic activity for methanol oxidation as compared with both Pt NP/chemically reduced graphene oxide (Pt/r-GO) and state-of-the-art Pt/C catalyst. The observed electrocatalytic activity also shows marked improvement over Pt/3D graphene prepared by pulse electrodeposition of Pt. This study demonstrates that protein Nanocage templating and assembly are promising strategies for the fabrication of functio...
