Abstract Bare, non-pretreated platinum wires and screen-printed platinum electrodes were used as both working and counter electrodes in the measurement of dissolved oxygen using a chronoamperometric method. The oxygen reduction current response in the diffusion state was used for a linear determination of air saturation. We evaluated the two different materials in general for their sensing performance such as conditioning time, accuracy, resolution and stability over 13 h of continuous mid-term measurement. A good performance was found for the wire electrodes in terms of accuracy with a current slope of 1.0–1.6 µA (% as)-1 and a resolution of 10–15 nA (Lowest Level of Detection = 0.1% as), but with an unstable current response result over the course of the measurement. The screen-printed electrodes have a resolution of 10–18 nA (Lowest Level of Detection = 0.6–0.8% as) and an accuracy of 620–660 nA (% as)-1 but they showed promising reproducibility and stability. Both materials require several hours of conditioning in the chronoamperometric method before a stable current response is achieved. For biotechnological applications, the platinum screen printed electrodes were evaluated in typical parameter settings (pH 4.0 and 7.4, salinity 0.1 to 10x phosphate buffered saline and temperature 12 to 42 °C) and showed correlations between the response time and stability and the temperature. No correlations were found between salinity, pH and the current response. In this paper, we present inexpensive electrode materials and a simple to implement chronoamperometric method for reliable direct measurement of dissolved oxygen in aqueous media. Graphical abstract

Abstract Generation of hydrogen is very important, as it is one of the most desired alternatives to fossil fuels. Moreover, designing of cheap and stable electrocatalysts is the task for the efficient generation of hydrogen with reasonable activity. Materials hybridization can be considered a tool for engineering different material properties. Composites of modified silicon such as C–Si, Ni/(C–Si), Pt/(C–Si), and Pt–Ni/(C–Si) were prepared (in weight percent) and studied as electrocatalysts for the hydrogen evolution reaction (HER) in 0.5 M H 2 SO 4 solution. The surface morphologies and chemical compositions of the composites were confirmed using transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), X-ray fluorescence analysis (XRF), elemental mapping, and BET surface analysis. The electrochemical measurements of linear sweep voltammetry (LSV), Tafel plots, chronoamperometry, and electrochemical impedance spectroscopy (EIS) were used to study the behaviour of the prepared electrodes toward the hydrogen evolution process. Among the various prepared composites, [7%Pt–3%Ni]/[C–Si (1:1)] composite shows the best catalytic activity with the highest HER rate (940.95 µA cm −2 s −1 ), the lowest overpotential [0.358 V vs. (Ag/AgCl) ≈ 0.161 V vs. (RHE)] at 10 mA cm −2 , and the lowest charge transfer resistance (2.657 Ω) compared to other prepared electrodes. In addition, it gives the highest values of 4.219 × 10 −3 s −1 turn over frequency (TOF) and 642 mA g −1 mass activity. It shows good stability towards the hydrogen evolution reaction as the current density reaches about 34.28 mA cm −2 after 5 h. Graphical abstract
氢的产生是非常重要的，因为它是化石燃料最理想的替代品之一。此外，设计廉价、稳定的电催化剂是高效产氢和合理活性的任务。材料杂化可以被认为是一种工程不同材料性能的工具。制备了C-Si、Ni/(C-Si)、Pt/(C-Si)和Pt - Ni/(C-Si)等改性硅复合材料(以重量百分比计)，并对其在0.5 M h2so4溶液中作为析氢反应(HER)的电催化剂进行了研究。采用透射电子显微镜(TEM)、扫描电子显微镜(SEM)、能量色散x射线分析(EDX)、x射线光电子能谱(XPS)、x射线衍射(XRD)、x射线荧光分析(XRF)、元素映射和BET表面分析等方法对复合材料的表面形貌和化学成分进行了表征。采用线性扫描伏安法(LSV)、塔菲尔图(Tafel plots)、计时安培法(chronoperometry)和电化学阻抗谱(EIS)等电化学测量方法研究了制备的电极对析氢过程的行为。在各种制备的复合材料中，[7%Pt-3%Ni]/[C-Si(1:1)]复合材料的催化活性最好，在10 mA cm - 2时HER率最高(940.95µA cm - 2 s - 1)，过电位最低[0.358 V vs. (Ag/AgCl)≈0.161 V vs. (RHE)]，电荷转移电阻最低(2.657 Ω)。此外，它还给出了4.219 × 10−3 s−1的翻转频率(TOF)和642 mA g−1的质量活度的最大值。5 h后电流密度达到34.28 mA cm−2左右，对析氢反应具有良好的稳定性
