摘要：
The role of lithium aluminum germanium phosphate (LAGP) glass-ceramic (a lisicon structure) on catalysis of the oxygen reduction reaction (ORR) is investigated by conducting thermo gravimetric analysis (TGA), Brunauer-Emmett-Teller (BET) and cyclic voltammetry (CV) measurements. The analysis of the CV data reveals that the LAGP glass-ceramic possesses some inherent catalytic activity toward reduction of oxygen. However, the data also suggest an irreversible nature of the reaction. The TGA and BET data complement the CV results. The Lisicon family of materials appears to be an attractive catalyst for ORR.
