摘要

新型钯纳米颗粒催化燃烧氢传感器具有良好的振动性能和较低的功耗，在氢能源汽车中具有广阔的应用前景。然而，Pd NPs在高温下的烧结降低了灵敏度，限制了这些传感器的应用。为了提高Pd - NPs基无载流子催化燃烧H2传感器的耐久性，采用共电沉积法制备了钯铂合金纳米颗粒（PdPt NPs）。系统地研究了ppt纳米粒子的形貌和组成对传感性能的影响。结果表明，合金中的Pt原子可以限制Pd原子的迁移率，从而减少高温下粒子间的烧结。与纯PdPt NPs H2传感器相比，PdPt NPs H2传感器具有更高的灵敏度和线性度，其低功耗和耐用性显著提高。

Durable carrier-free catalytic combustion H2 sensor based on PdPt alloy nanoparticles

The new palladium nanoparticles (Pd NPs) based carrier-free catalytic combustion hydrogen (H₂) sensor presents a promising potential for H₂ energy vehicle due to excellent vibration and low power consumption. However, the sintering of the Pd NPs at elevated temperatures decreases the sensitivity, limiting the applications of these sensors. To enhance the durability of Pd NPs based carrier-free catalytic combustion H₂ sensor, palladium-platinum alloy nanoparticles (PdPt NPs) was fabricated on the filament by a co-electrodeposition method. The impact of morphology and composition of PdPt NPs on the sensing performance was systematically investigated. The results indicated that Pt atoms in the alloy can restrict the mobility of Pd atoms, which may reduce the sintering between particles at elevated temperatures. Compared to a pure Pd NPs H₂ sensor, the PdPt NPs H₂ sensor demonstrated superior sensitivity and linearity and their low power consumption and durability were significantly improved.

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
