Tuning the oxidation degree in sub-10 nm silver-oxide nanoparticles: From Ag2O monoxide to AgOx(x > 1) superoxide

Tchaplyguine, Maxim LU ; Zhang, Ch. ; Andersson, T. and Bjorneholm, O. (2014) In Chemical Physics Letters 600. p.96-102
Abstract
A preparation method for silver-oxide containing nanoparticles is described. The suggested approach allows varying the oxidation degree from monoxide to an oxygen-rich state resembling superoxide The method is based on magnetron reactive sputtering and vapour aggregation, and utilizes silver-oxygen interaction in the vapour phase - prior to the nanoparticle aggregation from the vapour. Synchrotron-based photoelectron spectroscopy - a local probing method with high chemical sensitivity - allows 'on-the-fly' analysis of the composition and oxidation degree in nanoparticles, before any deposition of the particles. Preparation and properties of oxygen-rich nanoparticles are discussed in connection to the catalytic processing of economically... (More)
