WebThe catalyst obtained using both strategies showed low power outputs and while Xiong et al. (2015) had a more durable catalyst than 20%Pt/C; it had a poor mass activity relative to current commercial catalysts such as TKK (0.016 vs. 0.2 mA/μg). WebWe have successfully developed the platinum-deposited hydrophobic catalyst named TKK (Tanaka Kikinzoku Kogyo K.K.)-H1P. This catalyst is fabricated especially for oxidation of tracer- level hydrogen isotopes over the room temperature range, even in the presence of saturated water vapor. The base material of TKK-H1P is a hydrophobic porous silicate. bowling near hyde park https://skyrecoveryservices.com

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.
