The initial oxygen reduction reaction activity of the composite catalyst was slightly higher than as-received Pt/C. The electrocatalytic activity after consecutive potential cycling tests of the composite catalyst was c.a. 1.3 times higher than non-modified Pt/C. The increased durability of the composite catalyst is attributed to the improved preservation of the electrochemically active Pt surface area with the addition of ruthenium oxide., Article, ELECTROCHEMISTRY COMMUNICATIONS. 33:123-126 (2013)}, pages = {123--126}, title = {Improving oxygen reduction reaction activity and durability of 1.5 nm Pt by addition of ruthenium oxide nanosheets}, volume = {33}, year = {2013} }
