Electrometric monitoring of water adsorption by porous glass modified with copper(II) oxide

Electrometric monitoring of water adsorption by porous glass modified with copper(II) oxide Modification of porous glass with copper(II) oxide with planar structure does not change the run of the water-adsorption isotherm, whereas in the case when nanoparticles are formed from the supported oxide, a cluster-type adsorption mechanism is operative when a relative pressure p/p 0 > 0.5 is reached.

It was shown that a porous glass with distributed copper(II)oxide planar layer can be used as a sensitive element of a resistive humidity sensor. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

Modification of porous glass with copper(II) oxide with planar structure does not change the run of the water-adsorption isotherm, whereas in the case when nanoparticles are formed from the supported oxide, a cluster-type adsorption mechanism is operative when a relative pressure p/p 0 > 0.5 is reached. These specific features are reflected in the different dependences of the electrical resistance of the samples on humidity. It was shown that a porous glass with distributed copper(II)oxide planar layer can be used as a sensitive element of a resistive humidity sensor.
