Abstract
Localised and directional micro-scale reduction of metal oxide surfaces, using a hydrogen-doped helium atmospheric pressure plasma jet.
Highlights
Gaseous plasmas are potent chemically reactive environments containing a rich mixture of highly reactive radicals and ions, including free electrons
We demonstrate that a low power (
The Cu 2p3/2 spectrum obtained from the pristine surface can be modelled with two main components centered at 932.3 and 934.7 eV with full width at half-maximum (FWHM) values of 1.2 and 2.8 eV
Summary
Gaseous plasmas are potent chemically reactive environments containing a rich mixture of highly reactive radicals and ions, including free electrons. A hydrogen-doped helium atmospheric pressure plasma jet (APPJ) is shown to be effective for the chemical reduction of metal oxides.
