In a direct methanol fuel cell system (DMFC), one of the drawbacks is crossover. Methanol from anode passes through membrane and enters cathode, causing mixed potential in cell. Only Pt-based catalysts are capable operating as cathode for oxygen reduction reaction (ORR) harsh acidic condition DMFC. However, it causes due to high activity toward oxidation Pt. To overcome this situation, developi...

The impregnation method was used to synthesize Pt and Pt3Co supported on MWCNTs applying NaBH4 as the reducing agent. The structure, morphology, and chemical composition of the electrocatalysts were characterized through SEM, XRD, and EDX. X-ray diffraction showed a good crystallinity of the supported Pt nanoparticles on the composites and showed the formation of Pt3<...

Efficient and stable oxygen evolution electrocatalysts are indispensable for industrial applications of water splitting hydrogen production. Herein, a simple practical method was applied to fabricate (Mo, Fe)P2O7@NF electrocatalyst by directly growing Mo/Fe bimetallic pyrophosphate derived from Prussian blue analogues on three-dimensional porous current collector. In alkaline media, the develop...

Series of Copper Ruthenium (Cu-Ru) bimetallic catalysts supported on γ-Al2O3 with different metal loading are prepared and investigated for catalytic wet air oxidation of ammonia to nitrogen. The ammonia decomposition activity was studied at three different temperatures i.e. 150oC, 200oC, and 230 oC and it is found that catalytic activity increases with the increase in temperature along with th...
