Raw and analysed data for contribution paper "Low temperature plasma deoxidation of copper surfaces"
<p><strong>Abstract</strong>: In this study, the application of a DBD plasma for metal deoxidation was shown on differently oxidized copper surfaces in an Ar/H<sub>2</sub> atmosphere at 100 hPa and room temperature. Plasma treatments with a discharge voltage of 11 kV and a frequency of 8.8 kHz yielded an almost complete deoxidation of samples with native Cu<sub>2</sub>O layers and samples with pre-oxidized CuO layers, both within minutes of the Ar/H<sub>2</sub> plasma treatment. The chemical state of the samples was characterized via X-ray photoelectron spectroscopy (XPS). The plasma was analysed by optical emission spectroscopy (OES). Additionally, confocal laser scanning microscopy (CLSM) images show that the employed deoxidation method did not change the morphology of the copper surfaces.</p>

Experimental files for Investigation of low temperature plasmas formed in low density gases surrounding laser produced plasmas
<p>Temporal and spectral investigation of plasmas produced by interaction of laser pulses, with gaseous mixtures, was performed. The interaction took place inside a small portion of dense gas mixture injected temporarily into a chamber filled with the same mixture under low pressure. High-temperature plasmas produced directly by the laser pulse were a source of soft x rays and charged particles, ionizing and exciting the surrounding gas. In this way, low-temperature plasmas were produced. The formation of low-temperature plasmas was studied using optical spectroscopy and streak imaging. The experimental data.zip file contains the experimental data from an optical spectrograph and optical streak camera.</p> <p>Work supported by the National Science Centre, Poland, grant agreement no. 2020/39/B/ST2/00509</p>
Data from: Plasma assisted CO2 methanation: effects on the low-temperature activity of a Ni-Ce catalyst and reaction performance
Ni-Ce three-dimensional material with macropore diameter of 146.6±8.4 nm were synthesized and used for methanation catalyst. Firstly, H2-reduction of catalyst was conducted in thermal fixed bed and plasma reactor respectively, then X-ray diffraction (XRD) and CO2 Temperature Programmed Desorption (TPD) experiments on the two reduced samples were carried out to reveal the plasma effect on catalyst's physicochemical properties. It was found that plasma reduction created more abundant basic sites for CO2 adsorption, especially the medium basic sites were even doubled compared with the thermal reduced catalysts. The plasma reduced catalyst exhibited excellent low-temperature activity, ca. 50~60 oC lower than the thermal catalyst (the maximum CO2 conversion point). Based on the optimum reduced catalyst, plasma effect in the reactor level was further investigated under high gas hour space velocity (GHSV) ~50000 h-1. The plasma reactor showed higher CO2 conversion capacity and efficiency than the thermal reactor.
