“…The linear ranges, LOD values, and sensitivity for DA detection on Ni-BTC@Ni 3 S 4 /CPE proposed in this study were compared with those reported for modified electrodes, and the results are shown in Table . ,,− The LOD value of Ni-BTC@Ni 3 S 4 /CPE for DA detection was calculated to be 0.016 μM, which is lower than that of other MOF-based electrodes. It is worth mentioning that the DA sensor fabricated in this study has the widest linear range of 0.05–750 μM compared with the DA electrochemical sensor reported so far.…”

In this study, a novel Ni-BTC@Ni3S4 composite was fabricated by solvothermal reaction using an in situ etching vulcanization strategy and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), electron paramagnetic resonance (EPR), and Brunauer–Emmett–Teller (BET) analyses. The existence of a sulfur vacancy and Ni3+ in the as-prepared vein-like Ni-BTC@Ni3S4 greatly promoted the electrochemical sensing activity of the materials. Herein, a simple electrochemical sensor (Ni-BTC@Ni3S4/CPE) has been fabricated and used for the detection of dopamine (DA). The current signal of the Ni-BTC@Ni3S4/CPE-modified electrode was linear with the concentration of DA in the range of 0.05–750 μM (R 2 = 0.9995) with a sensitivity of 560.27 μA·mM–1·cm–2 and a detection limit of 0.016 μM. At the same time, the sensor has good stability and anti-interference ability. This study could provide a new idea and strategy for the structural regulation of composite electrode-modified materials and sensitive sensing detection of small biological molecules.

The advance of efficient electrocatalysts for electrochemical water splitting is very significant for energy conversion systems, but it is hindered by the high overpotential of the oxygen evolution reaction (OER) by four-electron transfer. Herein, we report a variation of transition metal compound based on the Co–Fe Prussian blue analogue precursor. CoP/FeP, Co2N/Fe3N, and CoFe catalysts are synthesized in N2 atmosphere by phosphorization, nitridation, and calcination, respectively. After phosphorization, the synthesized mesoporous CoP/FeP nanocubes contribute to the improvement of the electrocatalyst performance by maintaining the shape of the precursor. The mesoporous structure of the CoP/FeP catalyst enhanced the electrochemically active surface area than other Co2N/Fe3N and CoFe catalysts, resulting in better OER performance with an overpotential of 279 mV at a current density of 10 mA∙cm-2, a Tafel slope of 74 mV∙dec-1, and good stability for 24 h with only 5.64 % degradation in alkaline solution (1.0 M KOH).
