H2 Sensor(氢气传感器)研究综述
H2 Sensor 氢气传感器 - This Pd/Mg/Ti NPs layers on Si substrate have lucrative advantages as an H2 sensor for fast response and highly stable sensing performance. [1] Additionally, the sensor shows high selectivity against other flammable gases, while consuming much lower power than the commercial catalytic combustion based H2 sensors. [2] Then, a matching WL-TENG with 3° center angle was series connected to H2 sensor to construct the self-powered H2 sensing system. [3] Consequently, Ga-doped ZnO porous NFs functionalized with Pt catalysts exhibited the highest C2H2 sensing responses among the current state-of-the-art C2H2 sensors (Ra/Rg = 26. [4] With the recent reillumination of the hydrogen economy around the world, the demand for H2 sensors is expected to increase rapidly. [5] A surface engineering approach is exploited to enhance the performance of H2 sensors consisting of a single-wall carbon nanotube film/graphene 3D electrode decorated with catalytic Pt nanoparticles using atomic layer deposition (Pt-NPs/SWCNTs/Gr). [6] We further investigated the CO2 reduction with and without metal cations in solution using scanning electrochemical microscopy in the surface-generation tip-collection mode with a platinum ultramicroelectrode as a CO and H2 sensor. [7] The results demonstrated that 3D nanoporous Pd films with appropriate particle size were a promising candidate for a H2 sensor. [8] It was then deposited onto a microheater to fabricate a H2 sensor. [9] Pd nanowire-based H2 sensors have attracted significant attention because of their superior sensing performance. [10] In this work, catalytic Cr metal overlayered TiO2/ITO nanocomposite films were synthesized by novel two step deposition using spray pyrolysis and electron beam evaporation and optimized for use as H2 sensors. [11] Thus, functionalized CNTs can be potentially utilized in various fields because their operation does not require high-temperature environments (unlike the currently used metal oxide-based H2 sensors), while the power consumption and explosion risks of these materials are easily reduced through a simple heat treatment process. [12] Most important, H2 sensors based on MoS2 FETs show desirable properties such as full reversibility and absence of catalytic metal dopants (Pt or Pd). [13] The long-term stability of such a multi-pass retro-reflection-cavity-enhanced PAS based C2H2 sensor was evaluated by an Allan deviation analysis. [14] The H2 concentrations at the CO sensor location were measured using H2 sensors and were correlated with the CO sensor response. [15] It is found that, Rh-MoSe2 monolayer behaves good adsorption and desorption performances upon H2 molecule, which allows its exploration of H2 sensor at room temperature. [16] H2 gas sensor using 2DEG at heterostructure such as AlGaN/GaN is another candidate for H2 detection, thus, H2 sensor using AlGaN/GaN is compared with Al2O3/SrTiO3 sensor. [17] The obtained CNP was further used to fabricate a H2 sensor, and then the effect of annealing temperature on gas sensitivity of SnO2/Ag2O CNP was investigated. [18] Using this method, the shortest response time (2 s to 1% H2 ) in comparison with those of Pd-based H2 sensors reported previously and a limit of detection below 1 parts per million (ppm) for Pd/Au and Pd/Pt bimetallic line arrays are achieved. [19] The results indicate that WO3 sensing materials could be a promising choice for synthesizing high-performance C2H2 sensors for the judgement of the early latent faults of the oil immersed transformer. [20]这种位于 Si 衬底上的 Pd/Mg/Ti NPs 层作为 H2 传感器具有有利可图的优势,可实现快速响应和高度稳定的传感性能。 [1] 此外,该传感器对其他可燃气体表现出高选择性,同时消耗的功率比基于商业催化燃烧的 H2 传感器低得多。 [2] 然后,将匹配的3°中心角的WL-TENG串联到H2传感器上,构建自供电H2传感系统。 [3] 因此,用 Pt 催化剂功能化的 Ga 掺杂 ZnO 多孔 NF 在当前最先进的 C2H2 传感器中表现出最高的 C2H2 传感响应(Ra/Rg = 26. [4] 随着最近全球氢经济的复苏,对氢气传感器的需求预计将迅速增加。 [5] 采用表面工程方法来提高 H2 传感器的性能,该传感器由使用原子层沉积 (Pt-NPs/SWCNTs/Gr) 装饰有催化 Pt 纳米颗粒的单壁碳纳米管薄膜/石墨烯 3D 电极组成。 [6] 我们使用扫描电化学显微镜在表面生成尖端收集模式下使用铂超微电极作为 CO 和 H2 传感器进一步研究了溶液中有和没有金属阳离子的 CO2 还原。 [7] 结果表明,具有适当粒径的 3D 纳米多孔 Pd 薄膜是 H2 传感器的有希望的候选者。 [8] 然后将其沉积在微型加热器上以制造 H2 传感器。 [9] 基于 Pd 纳米线的 H2 传感器因其卓越的传感性能而备受关注。 [10] 在这项工作中,催化 Cr 金属覆层 TiO2/ITO 纳米复合薄膜通过新型两步沉积使用喷雾热解和电子束蒸发合成,并优化用作 H2 传感器。 [11] 因此,功能化的 CNT 可以潜在地用于各种领域,因为它们的操作不需要高温环境(与目前使用的基于金属氧化物的 H2 传感器不同),而这些材料的功耗和爆炸风险很容易通过简单的方法降低热处理工艺。 [12] 最重要的是,基于 MoS2 FET 的 H2 传感器显示出理想的特性,例如完全可逆性和不存在催化金属掺杂剂(Pt 或 Pd)。 [13] 通过艾伦偏差分析评估了这种基于多通道回射腔增强 PAS 的 C2H2 传感器的长期稳定性。 [14] 使用 H2 传感器测量 CO 传感器位置处的 H2 浓度,并与 CO 传感器响应相关联。 [15] 研究发现,Rh-MoSe2单分子层对H2分子具有良好的吸附和解吸性能,使其能够在室温下探索H2传感器。 [16] 在异质结构中使用 2DEG(例如 AlGaN/GaN)的 H2 气体传感器是 H2 检测的另一个候选者,因此,将使用 AlGaN/GaN 的 H2 传感器与 Al2O3/SrTiO3 传感器进行比较。 [17] 获得的CNP进一步用于制造H2传感器,然后研究了退火温度对SnO2/Ag2O CNP气体灵敏度的影响。 [18] 使用这种方法,与先前报道的基于 Pd 的 H2 传感器相比,响应时间最短(2 秒至 1% H2),并且 Pd/Au 和 Pd/Pt 双金属的检测限低于百万分之 1 (ppm)实现了线阵。 [19] 结果表明,WO3传感材料可能是合成高性能C2H2传感器用于判断油浸式变压器早期潜在故障的一种很有前景的选择。 [20]
Performance H2 Sensor
This increases the demand for the development of high performance H2 sensors. [1] The realization of Pd nanostructure based on electrospun nanofibers offers a facile and cost effective way to fabricate high performance H2 sensor. [2] We expect that the present strategy of sericin-MoS2 combination will satisfy the demand for exfoliated MoS2 based high performance H2 sensors to-date. [3] These advances enable small-scale, high-performance H2 sensors for use in emerging hybrid renewable energy systems, including Internet of Things (IoT) or mobile systems. [4] This study demonstrated the possibility of a high performance H2 sensor created by combining metal oxide NWs with a catalyst such as Pd. [5]这增加了对开发高性能 H2 传感器的需求。 [1] 基于静电纺丝纳米纤维的 Pd 纳米结构的实现为制造高性能 H2 传感器提供了一种简便且具有成本效益的方法。 [2] 我们预计,目前的丝胶-MoS2 组合策略将满足迄今为止对基于剥离 MoS2 的高性能 H2 传感器的需求。 [3] 这些进步使小型、高性能 H2 传感器能够用于新兴的混合可再生能源系统,包括物联网 (IoT) 或移动系统。 [4] 这项研究证明了通过将金属氧化物纳米线与催化剂(如 Pd)相结合来创建高性能 H2 传感器的可能性。 [5]
Sensitive H2 Sensor
We present an ultra-sensitive H2 sensor operating in air and based on electrostatically formed nanowire (EFN) sensor decorated by palladium nanoparticles (Pd NPs). [1] Here, a novel one-step hydrothermal method is reported to construct Nb doped rutile/anatase TiO2 heterophase junctions for a highly sensitive H2 sensor. [2]我们提出了一种在空气中运行的超灵敏 H2 传感器,该传感器基于由钯纳米粒子 (Pd NPs) 装饰的静电形成纳米线 (EFN) 传感器。 [1] 在这里,报道了一种新颖的一步水热法来构建用于高灵敏度 H2 传感器的 Nb 掺杂金红石/锐钛矿 TiO2 异相结。 [2]
Robust H2 Sensor
Evidently, plasmonic sensors with a fast response time can be fabricated with thick, melt-processed nanocomposites, which paves the way for a new generation of robust H2 sensors. [1] The stability and selectivity of the sensor has been enhanced using H2 insensitive reference electrode (RE) and solid polymer electrolyte gas permeable membrane, respectively, which will aid new dimensions in designing robust H2 sensor at room temperature. [2]显然,具有快速响应时间的等离子体传感器可以用厚的、熔融加工的纳米复合材料制造,这为新一代稳健的 H2 传感器铺平了道路。 [1] 分别使用 H2 不敏感参比电极 (RE) 和固体聚合物电解质透气膜增强了传感器的稳定性和选择性,这将有助于在室温下设计坚固的 H2 传感器的新维度。 [2]
General H2 Sensor
The gas sensor can detect H2 gas across a wide range of concentrations, from 5 ppm to 1%, implying that it is a promising candidate for a general H2 sensor. [1] This sensor responds to a wide range of H2 concentration, especially from ~5 ppm to 1%, implying a promising candidate for a general H2 sensor. [2]该气体传感器可以检测从 5 ppm 到 1% 的各种浓度范围内的 H2 气体,这意味着它是通用 H2 传感器的有希望的候选者。 [1] 该传感器响应广泛的 H2 浓度范围,特别是从 ~5 ppm 到 1%,这意味着通用 H2 传感器的有希望的候选者。 [2]
