Electrocatalytic performance of Pd nanoparticles supported on TiO2-MWCNTs for methanol, ethanol, and isopropanol in alkaline media

Mn-doped nickeltitanate (Ni1−xMnxTiO3) as a promising support material for PdSn electrocatalysts for methanol oxidation in alkaline media

“…The lesser magnitude of the Tafel slope indicates the higher tolerance of the active electrocatalyst towards the poisoning species. 51 The results taken from this polarization experiment and the Tafel slope indicate that among the modi-ed three electrodes PdSn-MNT/C glassy carbon electrode system has the lowest Tafel slope (Fig. 8).…”

“…Electrochemical impedance spectroscopy has been widely used as a supporting method for cyclic voltammetry to investigate the charge transfer phenomena in the electrode-electrolyte interfacial properties of modied electrodes. 51,52 The impedance behaviour of PdSn-MNT/C electrode was studied in 1.0 mol L À1 methanol with added 0.5 mol L À1 KOH. The equivalent circuit of PdSn-MNT/C and Nyquist plot of the impedance graph as depicted in Fig.…”

Comparative Electrochemical and Electron Paramagnetic Resonance Study of the Mechanism of Oxidation of 2,3,5,6-Tetra-Me-Pyrazine-Di-N-Oxide as a Mediator of Electrocatalytic Oxidation of Methanol at Glassy Carbon and Multi-Walled Carbon Nanotube Paper Electrodes

“…Carbon nanomaterials, single-walled (SWCNT) and multi-walled (MWCNT) nanotubes, nanopaper, nanofibers, have been extensively studied as a promising material for fundamental research [10][11][12][13][14][15][16][17][18][19][20][21][22][23], technological applications [24][25][26][27][28][29][30][31][32][33] (electronic materials and sensors) and electrocatalysis [34][35][36][37][38][39][40][41][42][43][44][45][46] due to their unique structural and physical properties: high surface area, excellent electronic conductivity, high chemical stability, and a wide useful potential window. Therefore, it was reasonable to study the possibility of using such electrodes in the processes of electrocatalytic oxidation of organic compounds in the presence of electrochemically generated aromatic di-N-oxide radical cation.…”

Template synthesis of the Cu 2 O nanoparticle-doped hollow carbon nanofibres and their application as non-enzymatic glucose biosensors

“…To improve the practical application of one-dimensional materials, in recent years, researchers have combined metal and metal oxides with one-dimensional carbon-based materials [6,7]. The incorporation of metal or metal oxide nanoparticles with one-dimensional carbon-based materials may produce the synergistic effects and may lead to the improved property of the composites [8,9].…”
