“…Electrocatalytic oxidation of methanol is a critical step in DMFCs, and developing new and efficient anode catalysts in DMFCs has received an enormous amount of attention [3][4][5]. While Pt [6,7] and Pt-based [8,9] catalysts are best-known materials for methanol electro-catalytic oxidation in the DMFCs, the commercialization of fuel cells is severely hampered by the high cost, sluggish kinetics, and low stability of the platinum catalysts.…”

“…Direct methanol fuel cells (DMFC) have garnered interest in the portable devices and transportation industries because of their relatively low cost, high storage capabilities, low temperature operation, low-carbon emission, and high energy density [1][2][3]. However, issues pertaining to sluggish catalytic kinetics and instability of methanol delivery systems due to poisoning, limit their potential practical applications [4][5][6].…”

Abstract:Carbon modified TiO2 nanobelts (TiO2-C) were synthesized using a hydrothermal growth method, as a support material for palladium (Pd) nanoparticles (Pd/TiO2-C) to improve the electrocatalytic performance for methanol electrooxidation by comparison to Pd nanoparticles on bare TiO2 nanobelts (Pd/TiO2) and activated carbon (Pd/AC). Cyclic voltammetry characterization was conducted with respect to saturated calomel electrode (SCE) in an alkaline methanol solution, and the results indicate that the specific activity of Pd/TiO2-C is 2.2 times that of Pd/AC and 1.5 times that of Pd/TiO2. Chronoamperometry results revealed that the TiO2-C support was comparable in stability to activated carbon, but possesses an enhanced current density for methanol oxidation at a potential of −0.2 V vs. SCE. The current study demonstrates the potential of Pd nanoparticle loaded on hierarchical TiO2-C nanobelts for electrocatalytic applications such as fuel cells and batteries.

“…A lot of research studies have demonstrated that coating the electrode surface with conducting polymers (CPs) is an attractive approach for enhancing the power and scope of electrochemically modified electrodes [20,21]. CP matrices have been employed as catalyst support materials for the oxidation of small molecules in place of conventional supports, because when a catalyst is dispersed in carbon black, a part of the active sites remains inaccessible to the reactant molecules.…”

Silver nanoparticles were deposited on the surface of poly ortho-toluidine (POT) modified carbon paste electrode (n-Ag/POT/MCPE) by the electrochemical method. The electrocatalytic activity of the prepared modified electrode toward the hydrazine oxidation in alkaline solutions was evaluated using cyclic voltammetry (CV) and chronoamperometry (CHA) methods. The CV experiment showed that the n-Ag/ POT/MCPE electrode is electrochemically active toward the hydrazine oxidation, and a sharp increment in the current of hydrazine oxidation was observed with the increase of the hydrazine concentration. CHA results show stable steady state current (I ss ) for the hydrazine oxidation. A linear dependence of the I ss upon the hydrazine concentration was found in the range of 1.0×10 −4 to 6.0×10 −3 M hydrazine. Results imply that the n-Ag/POT/MCPE presents stable and significantly high electroactivity for the hydrazine oxidation.
