degree of the material is essential for improving the kinetic properties of sulfur cathodes. Moreover, the N content in chitosan leads to N-doping in BNPC, which not only enhances the electrical... (c) and pore size distribution plot (d) The deconvolution XPS results of C 1s spectra (Figure 2(c)) shows characteristic peaks of C–C/C=C (284.3 eV) and C–O (285.7.0 eV). N-doping of BNPC was proved......
and nitrogen doping can be performed by implantation of He, O and N in one step. After implantation, annealing at 650 ℃ leads to a mixing phase of anatase with a little rutile in the implanted layer... nitrogen containing compounds onto the surface of samples[17]. For the nitrogen doping dose of 8×1015 ion/cm2, b-N amount is higher than that for the nitrogen dose of 4×1015 and 12×1015 ion/cm2......
. The effects of calcination temperature, time and mole ratio of Ti to N on the photocatalytic activity were investigated. The results show that all catalysts are anatase, and the doping of nitrogen leads...TiO2的TG-DTA曲线 Fig.3 TG-DTA curves of N-doping TiO2 4个质量损失平台对应着3个吸热峰和3个放热峰.在133.23 ℃附近出现1个明显的吸热峰,这是尿素达到熔点熔化所致;在153.73 ℃附近出现1个放热峰,这是尿素分解成小分子氨气,氰酸等时放热所致;于196.55 ℃和246.05 ℃出现的峰分别对应吸热峰和......

Generally, rutile is a n-type semiconductor with high......
-like products are created. 3) The FT-IR spectra reflect the N-doping state of PNWs, CNFs and CNRs. 4) When evaluating the electrochemical properties, both CNFs and CNRs electrodes satisfied capacity... was dissolved in N-methyl- 2-pyrrolidone to produce homogeneous slurry with mortar and pestle. Then the obtained slurries were pasted onto pure Cu foils and dried at 120 °C. The electrolyte was 1 mol/L LiPF6......
of these copolymers positively shifted in comparison with those of MEH-PPV (0.41 V) and P3HT (0.05 V) measured under the same conditions. On sweeping the polymers cathodically, polymers exhibit reversible n-doping/dedoping process, the onset potentials of the n-doping process for PFN and PFNAn occurred at -1.54 and -1.57 V, respectively. The reduction potentials of these copolymers also positively shifted......
of electron [13-19]. So far, the preparation methods of N-C catalysts can mainly be classified as two categories. One is post-doping, namely the post-heating of the graphitic carbon together with N-containing composites. The nitrogen content of the catalysts synthesized by this method is usually too low to form enough active sites. The other is in-situ N atoms doping into the C skeleton during......
