The  sensitivity of gas-sensor has also been modified by  adding metals or metal oxides as catalytic agents.  Using the In2O3 and Ag nanoparticles as the  precursor; In2O3: Ag composite nanoparticle layers  have been grown. It has been demonstrated that a  decreasing particle size leads to an increased  sensitivity and a decreased response time. At C2H5OH  concentration of 1000 ppm in air and at an operating  temperature of 400°C, sensitivity and response time  of 325 and 8 s, respectively have been achieved in  case of In2O3 nanoparticles with a size of 14 nm.  With the addition of 15% silver, response time of 6 s  and sensitivity of 436 has been obtained for 1000 ppm  ethanol at 400°C. Ag2O nanoparticle draws electrons  from the In2O3 layer and enhances the formation of  electron-depleted layer. On exposure to a reducing  gas, interfacial Ag2O is reduced to Ag, with a  decrease or disappearance of the space-charge layer.  Gas sensing response thus depends on the change in  depletion layer in interface from Ag2O-In2O3 to  accumulation layer in Ag-In2O3.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838365404\"\u003e\u003ch3\u003eStructural, Optical and Gas Sensing Properties of In2O3 and In2O3: Ag Composite Nanoparticle Layers\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838365404","offer_id":39498932977757,"sku":"9783838365404","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ca702fe4-dbd5-4747-928e-b48816af765e.jpg?v=1757741290","url":"https:\/\/shop.autorenwelt.de\/products\/gas-sensing-properties-of-in2o3-and-in2o3-ag-nanoparticle-layers-von-vidya-nand-singh-und-b-r-mehta","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
