The drive to capture airborne carbon dioxide from industrial waste and make it into fuel and plastics is gaining momentum after a team of researchers at McMaster University and computational chemistry experts at Copenhagen\u2019s Danish Technical University uncovered precisely how the process works and where it bogs down.<\/p>\n\n\n\n

The researchers set out to resolve why synthetic materials that have been shown to catalyze and convert carbon dioxide break down too quickly for the process to be practical at an industrial level.<\/p>\n\n\n\n

Using extremely powerful magnification equipment at the Canadian Centre for Electron Microscopy (CCEM) on McMaster\u2019s campus, the researchers were able to capture the chemical reaction at nanoscale \u2014 billionths of a metre \u2014 allowing them to study both the conversion process and understand how the catalyst breaks down under operating conditions.<\/p>\n\n\n\n

Lead author Ahmed Abdellah spent years developing the techniques that made it possible to observe the process, using an electrochemical reactor small enough to work under the electron microscopes at the centre.<\/p>\n\n\n\n

\n

\u201cIt\u2019s exciting for us that this is the first time anyone has been able to look at both the shapes of these structures and their crystal structures, to see how they evolve at the nanoscale,\u201d says Abdellah, a former PhD student in the chemical engineering lab of Drew Higgins<\/a> and now a postdoctoral fellow at the CCEM.<\/p>\n<\/blockquote>\n\n\n\n

Higgins, a corresponding author of the paper<\/a>, newly published in the journal Nature Communications<\/em>, hopes the new information will facilitate the global effort to reduce carbon pollution by drawing carbon dioxide away from waste streams and instead recycling it to create useful products that would otherwise be produced from fossil fuels.<\/p>\n\n\n\n

\n

\u201cWhat we have found is that catalysts that can convert carbon dioxide into fuels and chemicals restructure quite rapidly under operating conditions. Their structures change and their properties change, right before our very eyes\u201d Higgins says.<\/p>\n\n\n\n

\u201cThat dictates how efficient they are at converting carbon dioxide and how long they last. The catalysts eventually degrade and stop working and we want to know why they do that and how they do that so that we can develop strategies to improve their operational lifetimes.\u201d<\/p>\n<\/blockquote>\n\n\n\n

Abdellah, Higgins and their colleagues are hopeful they and other researchers around the world can use the research results described in the new paper to make the reactive materials last longer and catalyze the process more efficiently, to allow the lab-based process to be scaled up for commercial use.<\/p>\n\n\n\n

Industries such as cement manufacturing, brewing and distilling, as well as chemical refineries produce high volumes of readily retrievable carbon dioxide, Higgins explains, making them likely first targets for rolling out the technology once it is improved to the point where it is commercially viable.<\/p>\n\n\n\n

Other less concentrated forms of CO2<\/sub> in industrial waste would come next.<\/p>\n\n\n\n

Though it\u2019s a longshot today, Higgins says it\u2019s possible the same technology could become efficient and stable enough to pull carbon dioxide from ambient air as \u201cfeedstock\u201d for fuel and useful chemicals.<\/p>\n\n\n\n

\n

\u201cWe\u2019re still a little ways off, but progress has been very rapid in this field of research and development in the last five years or so,\u201d Higgins says.<\/p>\n\n\n\n

\u201cTen years ago, people weren\u2019t thinking about this kind of conversion, but now we\u2019re starting to see promise. Efficiency and durability, though, just aren\u2019t high enough yet. Once these bottlenecks are removed, this idea can really take off.\u201d<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"
