Electrochemical Preparation, Characterization of Molybdenum-Oxide/Platinum Binary Catalysts and Its Application to Oxygen Reduction Reaction in Weakly Acidic Medium

Determination of Hydrazine at a Platinum Nanoparticle and Poly(Bromocresol Purple) Modified Carbon Nanotube Electrode

“…The 4f7/2 and 4f5/2 spectra of Pt were present at 71.56 and 74.77 electron volts, respectively, corresponding to platinum(0). The 4f7/2 and 4f5/2 peaks had separation energies close to 3.21 electron volts (Yavuz et al 2015). The binding energy of the surface of platinum nanoparticles modified poly(bromocresol purple) film and carbon nanotubes modified glassy carbon electrode indicated the majority of the platinum was present in the zero oxidation state.…”

A novel ethanol biosensor on pulsed deposited MnOx-MoOx electrode decorated with Pt nanoparticles

“…A former study carried out in this lab has revealed that pulsed deposited MoOx film further decorated with platinum nanoparticles displays catalytic activity towards the oxygen reduction reaction (ORR) [12]. Lee et al have reported a similar enhancement in the catalytic activity for manganese oxide (MnOx) modified electrodes which can be prepared in mixed valent form [13].…”

Electrochemical performance of lithium molybdenum composite catalyst in oxygen reduction reaction

“…In addition; platinum composites with low cost metal and their oxides such as vanadium, molybdenum, cobalt, chromium, and iron oxides also exhibit good catalytic efficiency towards ORR along [16,17].…”

“…Also, the calcination temperature has an effect on the preferred particle size [26,27]. Transition metals and their oxides are skilled to form chemical bonds with O 2 using their d orbitals [16], because of this properties, they have also been investigated as nonprecious metal electrocatalysts for ORR [28,29]. Recently studies, molybdenum oxides are highly popular because of their unique electronic and molecular structures in many catalytic applications [30].…”

“…Recently studies, molybdenum oxides are highly popular because of their unique electronic and molecular structures in many catalytic applications [30]. This can be attributed to the non-stoichiometric lower valence compositions between MoO 2 and MoO 3 simply given as MoOx [16,31].…”
