对比FeN2、SnN2与N2-Fe-Sn-N2模型,*OH在FeSn-C2N上的吸附能(0.66 eV)显著降低,区别于Sn-C2N(0.19 eV)和Fe-C2N(-0.18 eV)。强*OH吸附于Fe-C2N和Sn-C2N阻碍H2O生成,削弱ORR表现。而FeSn-C2N的弱*OH吸附特性,促进了*OH解吸与H2O形成,提升了ORR性能。因此,FeSn-C2N的弱*OH吸附是其ORR活性增强的...
6H2O (4 mmol) and FeCl2?4H2O (2 mmol) was prepared with an initial pH of 1.48. However, GO sheets are prone to stack together at such low pH solutions, thus diminishing the effective surface of GO45. To address this problem, GO was not added into the mixture until the pH was ...
Cells from anomaly above average ambient bottom water hybridizations made with 45% formamide showed temperature (1.49±0.002 1C) (Supplementary Figure little or no fluorescence with either Zeta-672 or S3). Surveys conducted around Ula Nui between Plancto-313 probes, whereas cells from hybridization...
The electron-transfer oxidation-reduction chemistry for meso-tetrakis(2,6-dichlorophenyl)porphine [(Cl8TPP)H-2] and its metal complexes [(Cl8TPP)M; M = Mn, Fe, Co, Ni, Cu, Ag, and Zn] has been characterized by cyclic voltammetry and controlled-potential electrolysis. Electron spin resonan...
