Tkk catalyst
WebDec 2, 2011 · To verify the applicability of our design approach for real electrocatalysts, we studied the conventional Tanaka Kikinzoku Kogyo (TKK) catalysts (5-nm Pt catalyst, Fig. 4C). Qualitatively similar trends were observed for nanocatalysts irrespective of shape or size variations, but we show only the results for the carbon-supported Pt catalysts here.
