“…Nanostructured WO 3 has a high specific surface area and good surface permeability, making it ideal for a wide range of applications. WO 3 nanostructures in various morphologies (for example, instant nanorods (NRs), nanosheet, 3D nanostructured papilio paris, and thin films (TFs)) have been fabricated for a variety of applications, including gas sensors [ 7 ], efficient water splitting [ 8 ], photoelectrocatalytic activity [ 9 ], memory devices [ 10 ], photodetectors [ 11 , 12 ], and high temperature diodes [ 13 , 14 ]. At present, nanostructured WO 3 are deposited on various substrates to fabricate optical and electrical devices, such as TiO 2 [ 15 ], NiO [ 16 ], ZnO nanowires (NWs) [ 17 ], diamond [ 14 ], Fe 2 WO 6 [ 8 ], and BiVO 4 [ 18 ].…”

Tungsten oxide (WO3) is a wide band gap semiconductor with unintentionally n−doping performance, excellent conductivity, and high electron hall mobility, which is considered as a candidate material for application in optoelectronics. Several reviews on WO3 and its derivatives for various applications dealing with electrochemical, photoelectrochemical, hybrid photocatalysts, electrochemical energy storage, and gas sensors have appeared recently. Moreover, the nanostructured transition metal oxides have attracted considerable attention in the past decade because of their unique chemical, photochromic, and physical properties leading to numerous other potential applications. Owing to their distinctive photoluminescence (PL), electrochromic and electrical properties, WO3 nanostructure−based optical and electronic devices application have attracted a wide range of research interests. This review mainly focuses on the up−to−date progress in different advanced strategies from fundamental analysis to improve WO3 optoelectric, electrochromic, and photochromic properties in the development of tungsten oxide−based advanced devices for optical and electronic applications including photodetectors, light−emitting diodes (LED), PL properties, electrical properties, and optical information storage. This review on the prior findings of WO3−related optical and electrical devices, as well as concluding remarks and forecasts will help researchers to advance the field of optoelectric applications of nanostructured transition metal oxides.

“…In addition, a close-knit collaborative research network has been formed with Yang, M.H as the root, and Yang, M.H, together with Dai, J.X., etc., has assumed an important intermediary role. For example, WO 3 -Pd 2 Pt-Pt nanocomposite films were deposited on a single mode fiber (Jeunhomme, 1990; Rashleigh, 1983) as the hydrogen sensing material in Dai et al (2021), which changes its reflectivity under different hydrogen concentrations. The reflectivity variation was probed and converted to an electric signal by a pair of balanced InGaAs photoelectric detectors (Lai et al , 2014); five types of hydrogen sensors were focused on, including interference type, micromirror type, evanescent field type, surface plasmon resonance type and fiber Bragg grating type, and their structures, characteristics and sensing performances are critically overviewed in Wang et al (2021).…”

Purpose With the acceleration of global energy structure transformation, hydrogen has been widely used for its non-pollution and high efficiency, and hydrogen detection is used to guarantee the hydrogen safety. The purpose of this paper is to study the research foundation, trend and hotspots of hydrogen detection field. Design/methodology/approach A total of 4,076 literature records from 2000 to 2021 were retrieved from the core collection of the Web of Science database selected as data sources. The literature information mining was realized by using CiteSpace software. Bibliometrics was used to analyze information, such as keywords, authors, journals, institutions, countries and cited references, and to track research hotspots. Findings Since the 21st century, the number of publications in the hydrogen detection field has been in a stable stepped uptrend. In terms of research foundation, the hotspots such as core-shell structures, nano-hybrid materials and optical fiber hydrogen sensors have been studied extensively. In combination with the discipline structure and research frontier, the selectivity, sensitivity, response speed and other performance parameters of hydrogen sensors need further improvement. The establishment of an interdisciplinary knowledge system centered on materials science and electronic science will become a long-term trend in the research of hydrogen detection. Originality/value This study presents an overview of research status, hotspots and laws in hydrogen detection field, through the quantitative analysis of much literature in the field and the use of data mining, so as to provide credible references for the research of hydrogen detection technology.

The development of hydrogen sensors has acquired a great interest from researchers for safety in fields such as chemical industry, metallurgy, pharmaceutics or power generation, as well as due to hydrogen’s introduction as fuel in vehicles. Several types of sensors have been developed for hydrogen detection, including resistive, surface acoustic wave, optical or conductometric sensors. The properties of the material of the sensitive area of the sensor are of great importance for establishing its performance. Besides the nature of the material, an important role for its final properties is played by the synthesis method used and the parameters used during the synthesis. The present paper highlights recent results in the field of hydrogen detection, obtained using four of the well-known synthesis and deposition methods: sol-gel, co-precipitation, spin-coating and pulsed laser deposition (PLD). Sensors with very good results have been achieved by these methods, which gives an encouraging perspective for their use in obtaining commercial hydrogen sensors and their application in common areas for society.
