Effective improvement of sensing performance of amperometric NO2 sensor by Ag-modified nano-structured CuO sensing electrode

Review—Recent Advancements of ZnO/rGO Nanocomposites (NCs) for Electrochemical Gas Sensor Applications

“…Thus, gas detection materials have gained immense research attention across the world for fabricating efficient NO 2 sensors which work in ambient temperatures. 66 Liu et al (2017) constructed a ZnO/rGO sensor for selective detection of NO 2 by thermal reduction followed by a soft solution method. 67 The hybrid sensor demonstrated excellent performance from 5 to 50 ppm NO 2 with better response 9.6, and rapid responses at (15-25 s).…”

Influence of defect on the electrical and optical properties of A-site non-stoichiometry Ca0.67La0.22□0.11Ti(1−x)CrxO3−δ perovskite

“…1 To monitor NO X emission, lots of efforts have been made to develop high performance and compact solid electrolyte NO X type sensors with a stable, sensitive, selective and quick response. [2][3][4][5][6][7][8] Yttrium Stabilized Zirconia Y 4x Zr 1À4x O 2À2x (YSZ) has exceptionally high ionic conductivity but only at a temperature beyond 800 C. Its high operating temperature, however, can lead to many problems; it limits the selection of compatible electrodes and interconnect materials 9 and reduces the service life of the sensor. 10 Thus, it is urgent to search for an alternative oxide electrolyte material that can capture NO X at a mild temperature.…”

Kinetics of Adsorption of Acid Red 1 Onto Chitosan and Cross-Linked Chitosan From Aqueous Solution

“…Various chitosan based composites have been designed to overcome these problems. Integration of an adsorbent with other materials through methods such as grafting, impregnation, chelation and crosslinking has better adsorption properties than the individual components effects [4][5][6]. Composite adsorbents can be prepared with the sole aim of enhancing their selectivity, regeneration, surface area, mechanical strength and surface chemistry amongst others.…”
