高于具有Co-N4和Ni-N4位点的Co-N/NPCNSs(1205 h-1和61.5%)和Ni-N/NPCNSs(404 h-1和45.0%)。 3)原位同步辐射傅里叶变换红外(FTIR)光谱和密度泛函理论(DFT)计算表明,N桥联的Con-Ni双金属位点促进了COOH*中间体的形成,从而加速了CO2RR。因此,N桥连接的双金属位点是一种电子调谐的有效结构,从而提高了催化...
此外,利用Ni3N/Co3N-NWs组装的流动池仅需2.01 V的电压就能产生1 Acm−2的工业级电流密度,以及对甲酸盐和H2的产率分别达到11和21.4 mmol cm−2h−1。 原位拉曼光谱和原位SR-FTIR揭示了GOR过程在Ni3N/Co3N异质界面上的综合机制和主要的甘油转化途径。 此外,密度泛函理论(DFT)计算证明了在Ni3N/Co3N上构建...
SR-FTIR观察到重要的NHCO相关振动模式,从而证明CO-NH耦合的发生,有利于尿素的合成。 DFT计算结果表明NiFe-DSAC催化NO3还原至NH的决速步为NO--NOH,势垒为0.62 eV。C-N耦合发生在NH与CO,以及NHCO与NO之间,动力学势垒分别为0.21 eV和0.09 eV。 原文链接:https://doi.org/10.1038/s41467-022-33066-6 ...
Metal ion interactionComplexes of Co(II), Ni(II), Cu(II), and Zn(II) with N,N′-(aldose)2–thiocarbohydrazide (LH2) were synthesized, isolated as solid products and characterized by analytical means as well as by spectral techniques, FTIR, 1H NMR, EPR, UV spectroscopy, and CD. All ...
A series of characterization studies such as SEM, XRD, TEM, EDX, XPS, UV鈥搗is DRS, FTIR, transient fluorescence and electro-chemistry etc. show that the more active sites appears and the efficiency of photo-generated charge separation is improved due to the introduction of surface N ...
Sodium-ion batteryCoupled TGA-FTIRSol-gelImpedanceLayered oxideAmong the various cathode materials explored for sodium-ion batteries (SIBs), NaMn 0.33 Ni 0.33 Co 0.33 O 2 , with a layered oxide structure, is a promising material due to its high theoretical capacity (240mAhg 1 ). We have ...
3.2. FTIR spectroscopy The IR spectra of 1 and 2 were analyzed in comparison with that of their free ligand HL1 from 4000–400 cm−1. The strong sharp absorption at 1661 cm−1 in spectra of HL1 can be assigned to C=N stretch; in the complexes, these bands are shifted to lower ...
