Carbon-supported Pt-Fe alloy as a methanol-resistant oxygen-reduction catalyst for direct methanol fuel cells

Shukla, A.K.; Raman, R.K.; Choudhury, N.A.; Priolkar, K.R.; Sarode, P.R.; Emura, S.; Kumashiro, R. (Journal of Electroanalytical Chemistry. 563(2); 2004; 181-190.)

Crossover of methanol from the anode to the cathode through the polymer-electrolyte membrane in solid-polymer-electrolyte direct methanol fuel cells constitutes a significant loss in their performance. Pt/C and Pt-Fe/C ...
Effect of protonated amine molecules on the oxygen reduction reaction on metal-nitrogen-carbon-based catalysts

Karthikayini, M.P.; Wang, G.; Bhobe, P.A.; Sheelam, A.; Ramani, V.K.; Priolkar, K.R.; Raman, R.K. (Electrocatalysis. 8(1); 2017; 74-85.)

Non-precious metal electrocatalysts based on pyrolyzed metal, nitrogen, and carbon (MNC) are viewed as an inexpensive replacement for platinum-based electrocatalysts for the oxygen reduction reaction (ORR) in fuel cells. ...
Tailoring a Pt-Ru catalyst for enhanced methanol electro-oxidation

Raman, R.K.; Shukla, A.K.; Gayen, A.; Hegde, M.S.; Priolkar, K.R.; Sarode, P.R.; Emura, S. (Journal of Power Sources. 157(1); 2006; 45-55.)

A carbon-supported (1:1) Pt-Ru (Pt-Ru/C) alloy catalyst has been prepared in-house by the sulfito-complex route, and has been tailored to achieve enhanced activity towards methanol electro-oxidation by annealing it at ...
