“…Furthermore, the B 1s peak (Fig. 32 The presence of P-C 3 confirmed the phosphorus had been doped into the carbon materials and P-O bonding implied the doped P atoms might be partially oxidized in the heat treatment. 15,16,31 The existence of B-C 3 bonding confirmed that boron was successfully doped in NBCNH.…”

Heteroatom doped single-walled carbon nanohorns are produced via a facile one-step arc discharge method and used as metal-free catalysts for the oxygen reduction reaction (ORR). The influence of nitrogen-source on the structure and electrocatalytic activity of the nanohorns is studied. Two kinds of N doped carbon nanohorns produced by N2 or melamine as the N-source, respectively, present similar structure. However, dual-doped carbon nanohorns fabricated from different N-sources possess different structures. NB-dual doped carbon nanohorns synthesized by N2 would contain the enormous h-BN, which is chemical-inert for ORR. But using melamine as the N-source would prevent this phenomenon and raise the doping of B atoms into the graphene lattice, which lead to the increased ORR catalytic activity. Different with NB-dual doping, NP-dual doping via N2 would greatly give a rise to the content of N atoms into the materials, and result in the enhanced limited current intensity.Please do not adjust margins Please do not adjust margins As the attractive potential candidate for ORR electrocatalyst, the corresponding tolerance to methanol and stability of NBCNH-m were further investigated. The methanol crossover, The different N-sources used in the preparation would lead to different ways the doped N atoms interact with B or P dopants, and result in the enhanced or declined electrocatalytic activity of dual-doped carbon nanohorns in oxygen reduction reaction.

“…A platinum wire and a saturated calomel electrode (SCE) were used as the counter electrode and the reference electrode, respectively. In order to fully characterize the ORR efficiency of Co/N/C catalyst, RRDE measurement was performed to calculate the electron-transferred number (n), a significant kinetic parameter to characterize the ORR efficiency of Co/N/C catalyst (Fig.4b) (4) where I d is the disk current, I r is the ring current and N is the current collection efficiency (N=0.42). 4a, the electron-transferred number of the Co/N/C catalyst is calculated to be about 3.51 at the potential range from -0.7 to -0.9V, indicating an effective four-electron process of ORR.…”

Here we first time report, the investigation of stable surface oxidized graphite electrode prepared via the anodic oxidation of graphite in different electrolyte medium such as KOH, H2SO4 and KH2PO4. In the electrochemical surface oxidation route, high-quality graphene oxide was produced on the surface of the graphite rod. Formation of graphene oxide was proved with help of different techniques like X-ray diffraction, Raman spectroscopy analysis ,Fourier transform infrared spectroscopy etc. Synthesis produce was also distinguished with the help of scanning electron microscopy (SEM), etc. Simultaneous determination of 191mV Ascorbic acid (AA), 359mV Dopamine (DA) and 486mV Uric acid (UA) was done with the surface oxidized graphite electrode. Fast as well as sensitive electrochemical effect for finding of AA, DA and UA at potential between 0 to 1 V in the linear reaction series between 1µM to 10 mM with detection boundary (S/N = 3) of 1.04 µM (AA), 0.1µM (DA) and 0.108µM (UA) were obtained. These results demonstrated that the electrochemically surface modified graphite electrode displayed a superior presentation along with elevated sensitivity and long-lasting stability.
