While more research needs to be done, it\u2019s a crucial first step to delivering storage of solid carbon.\u201d<\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"font-size:12.0pt\">Lead author Dr. Dorna Esrafilzadeh, a Vice-Chancellor\u2019s Research Fellow in RMIT\u2019s School of Engineering, developed the electrochemical technique. The researchers designed a liquid metal catalyst with specific surface properties that made it extremely efficient at conducting electricity, while chemically activating the surface. The carbon dioxide is dissolved in a beaker filled with a liquid electrolyte and a small amount of the liquid metal, which is then charged with an electrical current.&nbsp;<\/span><\/span><span style=\"line-height:normal\"><span style=\"font-size:12.0pt\">The CO<span style=\"font-size:12px;\"><sub>2<\/sub><\/span> slowly converts into solid flakes of carbon, which are naturally detached from the liquid metal surface, allowing the continuous production of carbonaceous solid.<\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"font-size:12.0pt\">Dr. Esrafilzadeh says the carbon produced could also be used as an electrode. \u201cA side benefit of the process is that the carbon can hold electrical charge, becoming a supercapacitor, so it could potentially be used as a component in future vehicles. The process also produces synthetic fuel as a by-product, which could also have industrial applications.\u201d<\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"font-size:12.0pt\">The paper is published in <i>Nature Communications<\/i> (\u201cRoom temperature CO2 reduction to solid carbon species on liquid metals featuring atomically thin ceria interfaces\u201d, DOI: 10.1038\/s41467-019-08824-8).<\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"font-size:12.0pt\"><a href=\"https:\/\/www.rmit.edu.au\/\">https:\/\/www.rmit.edu.au\/<\/a> <\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>RMIT University in Melbourne, Australia, announces that its researchers have developed a molten metal catalyst technique that can efficiently convert carbon dioxide from a gas into solid particles of carbon.<\/p>\n","protected":false},"author":63082,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[453,443,456,440,441,1],"tags":[],"class_list":["post-8431","post","type-post","status-publish","format-standard","hentry","category-electronics","category-fossil-fuel-power","category-nanotechnology","category-news","category-news-articles","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 -
