“…Vibrations of a Fe-O bond are reported at 538 and 634 cm −1 and of a Fe 2 Ni-O bond at ca. 720 cm −1 , which is also in the range of the vibration of a Co-O bond (725 cm −1 ) [53][54][55]. Fe-O could not be detected and the Fe 2 Ni-O and Co-O bonds are all in a similar range to each other and to aromatic vibrations (Table S2, SI).…”

The exploration of earth-abundant electrocatalysts with high performance for the oxygen evolution reaction (OER) is eminently desirable and remains a significant challenge. The composite of the metal-organic framework (MOF) Ni10Co-BTC (BTC = 1,3,5-benzenetricarboxylate) and the highly conductive carbon material ketjenblack (KB) could be easily obtained from the MOF synthesis in the presence of KB in a one-step solvothermal reaction. The composite and the pristine MOF perform better than commercially available Ni/NiO nanoparticles under the same conditions for the OER. Activation of the nickel-cobalt clusters from the MOF can be seen under the applied anodic potential, which steadily boosts the OER performance. Ni10Co-BTC and Ni10Co-BTC/KB are used as sacrificial agents and undergo structural changes during electrochemical measurements, the stabilized materials show good OER performances.

Among reported electrode materials, a nanoarray is an attractive architecture for molecular detection because of its large specific surface area and easy accessibility for target molecules. Here, a new Fe N-Co N nanowires array grown on carbon cloth (Fe N-Co N/CC) is reported as a non-noble-metal bifunctional catalyst electrode for high-performance glucose oxidation and H O reduction. As an electrochemical non-enzymatic sensor for glucose detection, Fe N-Co N/CC shows a fast response time of 8 s, a low detection limit (LOD) of 77 nm (signal/noise=3), and a high sensitivity of 4333.7 μA mm cm . As an H O sensor, it shows a LOD of 59 nm (signal/noise=3) and a sensitivity of 2273.8 μA mm cm with a response time of 2 s. In addition, the proposed sensor is stable with high selectivity, specificity, and reproducibility, and its application for real sample analysis has been successfully demonstrated.

“…Presence of peak at 23° confirms the incorporation of rGO in MOF/rGO composites with its non‐interference nature, the intensity of peak is lower due to presence of metal sharp peak in the same region . Existence of cobalt is indicated by peaks at 28, 34 and 53 while formation of metal oxides and hydroxides during fabrication and further processing is shown by peaks at 2 θ value 18, 31, 32, 38, 45, 51, 56, 60, 68 and 78 . Peak at 43° is due to presence of metallic cobalt (JCPDS cards #15‐0806) or surplus carbon content of rGO .…”

In this research, electrocatalytic activity of cobalt benzene tricarboxylic acid metal organic framework (Co BTC MOF) and its reduced graphene oxide based composites (rGO/Co BTC) were investigated in an alkaline media for the methanol oxidation reaction (MOR). Metal Organic frameworks (MOF) and their composites were solvothermally prepared and characterized via FTIR, EDX, SEM and XRD. Electrochemical studies were performed by cyclic voltammetry, electron impedance spectroscopy, chronoamperometry and cyclic stability. Among all the prepared composites, 1 wt % rGO/Co BTC MOF (1.07 mg cm À 2 ) demonstrated a promising current density of 130 mA cm À 2 at 1.59 V vs. RHE, a tafel slope of 83.6 mV dec À 1 and resistance of 14.75 Ω in 1 M NaOH/ 2 M methanol solution showing much better performance than state-of-the-art Pt based materials.[a] L.
