  1. Electrocatalysis of Alcohol Oxidation and Oxygen Reduction at High pH Environments Qingang He, Nagappan Ramaswamy, and Sanjeev Mukerjee • Breakthrough Materials for Alcohol Oxidation • Remarkable improvements in ethanol oxidation performance • has been observed on platinum with millimolar concentrations • of the transition metal complex. • Metal organic complex dissolved in ethanol fuel as an additive • cleaves the C=C double bond via a coupled chemical and • electrochemical reaction mechanism on the Pt surface • Cleavage of C=C double bond and evolution of CO2 has been • confirmed using both surface sensitive XAS analysis (Delta-Mu) • and Differential Electrochemical Mass Spectrometry (DEMS) • Oxygen reduction on non-noble metal surface involving pyrolyzed • metal macrocyle has been observed to exhibit ORR activity similar • to that of platinum • Combination of square wave voltammetry and insitu XANES has been • used to elucidate that the anodic redox potential shift of M(III)/M(II) with • increasing pyrolysis temperature as the key to improved ORR activity • Non-PGM Pyrolyzed Macrocyle • for Oxygen Reduction ORR Activity equal to Platinum Northeastern University Center for Renewable Energy Technology, Boston
