MXene/WS₂hybrids for visible-light-activated NO₂sensing at room temperature

Abstract

OPTOELECTRONIC GAS SENSORS BASED ON TWO-DIMENSIONAL (2D) MATERIALS ARE TOUTED AS POTENTIAL CANDIDATES FOR NO2 SENSING AT ROOM TEMPERATURE. HOWEVER, MOST OF THE DEVELOPED OPTOELECTRONIC SENSORS TO DATE ARE CONFINED...

Visible-light-driven photocatalytic N2 fixation to nitrates by 2D/2D ultrathin BiVO4 nanosheet/rGO nanocomposites

“…Two-dimensional (2D) nanostructured materials can offer a large surface-to-volume ratio, high surface energy and numerous active reaction sites on the surface, resulting in an excellent physicochemical activity. 19–21 Moreover, the construction of 2D/2D layered composites possess a large interfacial area owing to face-to-face contact and effective interfacial charge transfer ability. 22,23 Thus, in this work, we selected ultrathin BiVO 4 nanosheets with a high redox potential 24 as the host photocatalyst and reduced graphene oxide (rGO) as the cocatalyst.…”

Engineering van der Waals Materials for Advanced Metaphotonics

“…In recent years, a variety of 2D-materials-based optoelectronic devices have been designed and experimentally demonstrated due to their promising optical and electrical properties. Next, we will introduce some developed 2D-materials-based optoelectronic devices, including photodetectors, ,,− sensors, ,− and transistors, − in the following subsections.…”

“…In addition, 2D-materials-based optoelectronic gas sensors have been intensively investigated recently (refs , , , , and − ). For example, Pham et al proposed and experimentally demonstrated a graphene–MoS 2 optoelectronic gas sensor for low-concentration NO 2 gas sensing …”

A Flexible and Wearable Nylon Fiber Sensor Modified by Reduced Graphene Oxide and ZnO Quantum Dots for Wide-Range NO2 Gas Detection at Room Temperature

“…NO 2 gas sensors that can work at room temperature are particularly important because they have the advantages of low power consumption, no heating, and easy operation [ 2 , 3 ]. So far, many different types of NO 2 gas sensors that work at room temperature have been manufactured by using different sensitive materials [ 4 , 5 , 6 , 7 , 8 ]. Among them, wearable NO 2 gas sensors have the characteristics of flexibility, a light weight, and a low cost and important application potential and value in the field of wearable electronics [ 9 , 10 , 11 ].…”
