Size-selected, monodisperse Pd nanoparticles having well-defined size distributions have been synthesized. In Pd nanoparticles, a unique pulsed like hydrogen sensing response has been obtained in which electrical resistance increases due to electronic effect sharply followed by a sudden decrease due to geometric effect when the hydrogen is switched on. The hydrogen sensing response is studied at different H2 concentrations and measurement temperatures in size-selected and monodisperse Pd nanoparticles. Two types of sensing behaviours are observed as a function of H2 concentration: (i) a normally observed ¿saturated¿ response and (ii) a ¿pulsed¿ response. In the second approach of using bimetal layer, Cu and Ag thin film has been deposited onto Pd layers and hydrogenation properties have been studied. In Ag\/Pd bimetal layer system, the effect of converting the metal over layer from thin film (TF) to metal nanoparticle (NP) layers has been investigated.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783330063037\"\u003e\u003ch3\u003efor Enhanced Hydrogenation Properties\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783330063037","offer_id":39420620669021,"sku":"9783330063037","price":64.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/b381991e-47ff-4f15-9d37-2a86d6092eb6.jpg?v=1774931533","url":"https:\/\/shop.autorenwelt.de\/products\/palladium-nanoparticles-and-bimetal-palladium-layers-for-enhanced-hydrogenation-properties-von-manika-khanuja","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
