Ultrafast synthesis of continuous Au thin films from chloroauric acid solution using an atmospheric pressure plasma jet

Abstract

Continuous Au thin films can be made from chloroauric acid solution using an atmospheric pressure plasma jet.

Application of Plasma-Printed Paper-Based SERS Substrate for Cocaine Detection

“…The emission spectra from various excited states of molecules, radicals, ions and atoms were observed, indicating a highly reactive environment of the plasma discharge with a low gas temperature of 360 ± 30 K. The detailed optical emission measurement results are provided in the SI. Unlike the high-temperature N 2 plasma with a large amount of chloroauric acid on the surface presented by Wu et al [ 40 ], no excited AuCl molecules were observed. Maguire et al [ 41 ] suggested the high density of electrons in the plasma discharge may provide a rapid reduction of HAuCl 4 .…”

Time Evolution Characterization of Atmospheric-Pressure Plasma Jet (APPJ)-Synthesized Pt-SnOx Catalysts

“…Because our process is conducted at~510 • C, we use FTO glass substrates (Sigma-Aldrich, St. Louis, MO, USA) which can tolerate a higher processing temperature. [6,17,18] have been extensively investigated. Metals and metal oxides are common catalysts [19][20][21][22][23][24].…”

“…APPs with various heavy particle temperatures and charge densities can be produced by using different excitation methods and electrode configuration designs. The synergy between the reactive plasma species and heat can promote rapid chemical reactions during material processing [3][4][5][6]. APPs have been used for processing various types of materials, such as carbon nanotubes [3,7,8] and reduced graphene oxides [9][10][11].…”

“…APPs have been used for processing various types of materials, such as carbon nanotubes [3,7,8] and reduced graphene oxides [9][10][11]. Applications of APPs for surface cleaning or modification [12][13][14], deposition of metal oxides [15,16], and syntheses of metal compounds from liquid precursors [6,17,18] have been extensively investigated.…”

Scan-Mode Atmospheric-Pressure Plasma Jet Processed Reduced Graphene Oxides for Quasi-Solid-State Gel-Electrolyte Supercapacitors

“…Some APPs possess slightly higher electron density and moderate gas temperature of the order of hundreds of degrees Celsius. In such APPs, the synergetic effects of reactive species and heat trigger high plasma-chemical reactivity, thus affording ultrafast materials processing capability [12][13][14][15][16][17][18][19][20]. For example, a DC-pulse nitrogen APPJ shows high reactivity with carbonaceous materials and the processing times for carbon nanotubes (CNTs) and reduced graphene oxides (rGOs) are within 30 s [12,15,[18][19][20][21][22].…”
