随着全球能源危机和环境污染日益加剧,开发可持续的绿色能源技术已经成为当务之急.其中,水分解制氢作为一种清洁能源的生产方式,因其零排放和高能量密度的特点,而受到广泛的研究和关注.析氢反应(HER)和析氧反应(OER)是水分解过程的关键步骤,它们的反应效率直接影响整个制氢过程的能量转换效率.因此,开发高效的双功能电催化剂对于推动水分解技术的发展具有重要意义.本文制备了一种超低Ru掺杂的新型核壳纳米结构电催化剂,该催化剂生长在泡沫镍(NF)上,简称Ru-NiMoO_(4)@Ni_(3)(PO_(4))_(2)/NF.首先,通过水热法在NF上均匀生长了水合NiMoO_(4)纳米柱,并通过共价相互作用,确保其在垂直方向上有序排列.随后,采用超低浓度的RuCl_(3)对NiMoO_(4)纳米柱进行蚀刻,并通过磷酸化反应引入(PO_(4))^(3+)离子形成了Ni_(3)(PO_(4))_(2)壳层.这种设计克服了以往Ru易团聚的难题,保障了Ru的均匀分布,从而合成Ru-NiMoO_(4)@Ni_(3)(PO_(4))_(2)/NF催化剂.通过X-射线衍射、X-射线光电子能谱及透射电子显微镜等对催化剂的化学组分和微观结构进行了分析,证实其成功制备.元素分析结果表明,催化剂中Ru的含量仅为1.94 wt%,显著降低了其制备成本.电化学测试结果表明,该催化剂在HER和OER中均表现出较好的催化活性.在10和100 mA cm^(−2)电流密度下,HER的过电位分别为−14.8和−57.1 mV,Tafel斜率为35.8 mV dec^(-1),优于商业Pt/C催化剂;在100 mA cm^(−2)电流密度下,OER过电位为259.7 mV,Tafel斜率为21.6 mV dec^(−1),优于商业RuO_(2)催化剂.在全水解测试中,该催化剂在10和100 mA cm^(−2)时所需的电池电压分别为1.43和1.68 V,与其他自支撑材料相比表现出良好的性能.此外,该催化剂在150 h性能测试过程中表现出较好的稳定性.采用密度泛函理论计算研究了催化剂具有较好活性的内在机制.结果表明,其具有低水离解能垒(ΔGb=0.46 eV),接近零的HER自由吸附能(∆G*H=0.02 eV),低的OER自由吸附能量(ΔG*OOH−ΔG*OH=2.74 eV)和接近费米能级的高密度态.这些特性共同促进了电解水反应的高效进行.综上,本文研究开发的Ru-NiMoO_(4)@Ni_(3)(PO_(4))_(2)/NF双功能催化剂具有较好的催化活性、低电位需求和长期稳定性,为氢气生产开辟了新途径,也为优化双功能水分解催化剂提供了新视角,并为未来可持续能源应用发展提供一定的参考.

Calibration of CO and CO₂ Monitors Used in Periodic Inspection of Vehicles at Fixed Stations for Environmental Control

引用

Green and Sustainable Chemistry 2024年第2期14卷 29-41页

作者： adel Bassuoni Shehata Abdulrahman Rashed Al Askar Najjy Hamad Al Yami Abdullah Suleiman Al Owaysi Sultan K. Alharbi Chemistry Department National Measurement and Calibration Center (NMCC) Saudi Standards Metrology and Quality Organization (SASO) Riyadh Kingdom of Saudi Arabia

Global efforts for environmental cleanliness through the control of gaseous emissions from vehicles are gaining momentum and attracting increasing attention. Calibration plays a crucial role in these efforts by ensuring the quantitative assessment of emissions for informed decisions on environmental treatments. This paper describes a method for the calibration of CO/CO2 monitors used for periodic inspections of vehicles in cites. The calibration was performed in the selected ranges: 900 - 12,000 µmol/mol for CO and 2000 - 20,000 µmol/mol for CO2. The traceability of the measurement results to the SI units was ensured by using certified reference materials from CO/N2 and CO2/N2 primary gas mixtures. The method performance was evaluated by assessing its linearity, accuracy, precision, bias, and uncertainty of the calibration results. The calibration data exhibited a strong linear trend with R² values close to 1, indicating an excellent fit between the measured values and the calibration lines. Precision, expressed as relative standard deviation (%RSD), ranged from 0.48 to 4.56% for CO and from 0.97 to 3.53% for CO2, staying well below the 5% threshold for reporting results at a 95% confidence level. Accuracy measured as percent recovery, was consistently high (≥ 99.1%) for CO and ranged from 84.90% to 101.54% across the calibration range for CO2. In addition, the method exhibited minimal bias for both CO and CO2 calibrations and thus provided a reliable and accurate approach for calibrating CO/CO2 monitors used in vehicle inspections. Thus, it ensures the effectiveness of exhaust emission control for better environment.
