Novel NiCo2O4 nanoarrays have been in-situ grown on a La0.8Sr0.2MnO3-δ(LSM) cathode through a hydrothermal method, which presents the enhanced electrochemical performances of the LSM cathode for the intermediate temperature solid oxide fuel cells. XRD and SEM have been used to characterize phase structure and morphology of NiCo2O4 nanoarrays. The LSM cathode, modified by the NiCo2O4 nanoarrays, exhibits excellent electrochemical performances compared with the bare LSM cathode. The maximum peak power density of single cell, based on the NiCo2O4 nanoarrays modified the LSM cathode, reaches 957 mW cm?2 at 800 °C, which is almost two times higher than that for the cell based on the bare LSM cathode. 相似文献

The exploration of substrate materials to construct electrochemical biosensors for glucose monitoring in the field of clinical diagnosis, especially for diabetes is still being investigated extensively. In this paper, NiO/Fe2O3 nanocomposites are designed and synthesized by two-step hydrothermal approach in combination with calcinations. The morphology and microstructure are studied by SEM, XRD, XPS, and TEM systematically. Optimized NiO/Fe2O3 nanocomposites are employed as substrate to construct glucose biosensors, and the electrochemical properties are carried out by cyclic voltammetric and chronoamperometric techniques. The results indicate as-prepared biosensors achieve a high sensitivity of 230.5 μA cm?2 mM?1, wide linear range between 50 and 2867 μM, and low detection limit of 3.9 μM towards glucose detection. The synergistic effect between NiO and Fe2O3 as substrate to construct glucose biosensors is elucidated. The selectivity is acceptable based on the detection of glucose concentration for diabetics. 相似文献

Pt nanoparticles modified Au nanowire array for amperometric and potentiometric detection of glucose
Kang Xu Guangqing Xu Jun Lv Jiewu Cui Yucheng Wu 《Journal of Solid State Electrochemistry》2013,17(9):2381-2389
A new glucose biosensor, based on the modification of highly ordered Au nanowire arrays (ANs) with Pt nanoparticles (PtNPs) and subsequent surface adsorption of glucose oxidase (GOx), is described. Morphologies of ANs and ANs/PtNPs were observed by scanning electron microscope. The electrochemical properties of ANs, ANs/GOx, ANs/PtNPs, and ANs/PtNPs/GOx electrodes were compared by cyclic voltammetry. Results obtained from comparison of the cyclic voltammograms show that PtNPs modification enhances electrochemical catalytic activity of ANs to H2O2. Hence, ANs/PtNPs/GOx biosensor exhibits much better sensing to glucose than ANs/GOx. Optimum deposition time of ANs/PtNPs/GOx biosensor for both amperometric and potentiometric detection of glucose was achieved to be 150 s at deposition current of 1?×?10?6 A. A sensitivity of 0.365 μA/mM with a linear range from 0.1 to 7 mM was achieved for amperometric detection; while for potentiometric detection the sensitivity is 33.4 mV/decade with a linear range from 0.1 to 7 mM. 相似文献

Self-supported and binder-free electrodes based on homogeneous Co3O4/TiO2 nanotube arrays enhanced by carbon layer and oxygen vacancies (Co3O4/co-modified TiO2 nanotube arrays (m-TNAs)) are prepared via a simple and cost-effective method in this paper. The highly ordered TNAs offer direct pathways for electron and ion transport and can be used as 3D substrate for the decoration of electroactive materials without any binders. Then, by a facile one-step calcination process, the electrochemical performance of the as-obtained carbon layer and oxygen vacancy m-TNAs is approximately 83 times higher than that of pristine TNAs. In addition, Co3O4 nanoparticles are uniformly deposited onto the m-TNAs by a universal chemical bath deposition (CBD) process to further improve the supercapacitive performance. Due to the synergistic effect of m-TNAs and Co3O4 nanoparticles, a maximum specific capacitance of 662.7 F g?1 can be achieved, which is much higher than that of Co3O4 decorated on pristine TNAs (Co3O4/TNAs; 166.2 F g?1). Furthermore, the specific capacitance retains 86.0 % of the initial capacitance after 4000 cycles under a high current density of 10 A g?1, revealing the excellent long-term electrochemical cycling stability of Co3O4/m-TNAs. Thus, this kind of heterostructured Co3O4/m-TNAs could be considered as promising candidates for high-performance supercapacitor electrodes. 相似文献

A highly sensitive amperometric nanobiosensor has been developed by integration of glucose oxidase (GOx) with a gold nanowires array (AuNWA) by cross-linking with a mixture of glutaraldehyde (GLA) and bovine serum albumin (BSA). An initial investigation of the morphology of the synthesized AuNWA by field emission scanning electron microscopy (FESEM) and field emission transmission electron microscopy (FETEM) revealed that the nanowires array was highly ordered with rough surface, and the electrochemical features of the AuNWA with/without modification were also investigated. The integrated AuNWA–BSA–GLA–GOx nanobiosensor with Nafion membrane gave a very high sensitivity of 298.2 μA cm−2 mM−1 for amperometric detection of glucose, while also achieving a low detection limit of 0.1 μM, and a wide linear range of 5–6000 μM. Furthermore, the nanobiosensor exhibited excellent anti-interference ability towards uric acid (UA) and ascorbic acid (AA) with the aid of Nafion membrane, and the results obtained for the analysis of human blood serum indicated that the device is capable of glucose detection in real samples. 相似文献
