Researchers at Brown University have found a way to fine-tune a copper catalyst to efficiently produce complex hydrocarbons \u2014 known as C2-plus products \u2014 from CO2.<\/p>\n

In a study <\/a>published in the journal Nature Communications<\/em>, the scientists report that the catalyst can produce C2-plus compounds with up to 72% faradaic efficiency. According to them, this is far better than previously reported efficiencies of other catalysts for C2-plus reactions.<\/p>\n

They also report that the preparation process can be scaled up to an industrial level fairly easily, which gives the new catalyst potential for use in large-scale CO2 recycling efforts.<\/p>\n

The catalyst could aid in large-scale recycling of CO2, for example, at mine sites<\/p>\n<\/blockquote>\n<\/figure>\n

\u201cThere had been reports in the literature of all kinds of different treatments for copper that could produce these C2-plus with a range of different efficiencies,\u201d said Tayhas Palmore, a professor of engineering who co-authored the paper with Ph.D. student Taehee Kim. \u201cWhat Taehee did was a set of experiments to unravel what each of these treatment steps was actually doing to the catalyst in terms of reactivity, which pointed the way to optimizing a catalyst for these multi-carbon compounds.\u201d<\/p>\n

Based on previous studies, Kim experimented with a variety of halogenation methods, as this process that coats a copper surface with atoms of chlorine, bromine or iodine in the presence of an electrical potential could increase a catalyst\u2019s selectivity of C2-plus products. After much testing, he zeroed in on which halogen elements and which electrical potentials yielded catalysts with the best performance in CO2-to-C2-plus reactions. He found that the optimal preparations could yield faradaic efficiencies of between 70.7% and 72.6%, far higher than any other copper catalyst.<\/p>\n

The researchers say that, ultimately, such a catalyst could aid in large-scale recycling of CO2, for example, at mine sites, power plants and other industrial facilities, to then convert it into other useful carbon compounds. <\/p>\n","protected":false},"excerpt":{"rendered":"
