전극재료용 나노 촉매 개발에 의한 DMFC 성능향상 연구

Abstract

Replication has been the mainstay for the molding that is required to synthesize a novel material on various length and shape using a removable template. Especially, considering that the various ordered molecular sieves have been emerged and are expected to come out, it is possible to synthesize new types of nanostructured metals and those materials are potentially useful in future catalysis, quantum-electronic devices and electrochemical sensing. Recently, metal replica prepared using highly ordered silica have been reported. However, these were single metal structures synthesized with Pt, Au or Ag precursor and the detail application has not been suggested yet, except for imaging the channels in mesoporous molecular sieves. We here report the synthesis of PtRu nanowire network made from SBA-15 template and show that these novel materials can be used as a good electrocatalyst for enhancing the performance of direct-methanol fuel cell (DMFC).
