Abstract

<jats:title>Small olefins from syngas</jats:title> <jats:p> The conversion of coal or natural gas to liquid fuels or chemicals often proceeds through the production of CO and H <jats:sub>2</jats:sub> . This mixture, known as syngas, is then converted to hydrocarbons with Fischer-Tropsch catalysts. For the light olefins (ethylene to butylenes) needed for chemical and polymer synthesis, conventional catalysts are mechanistically limited to <60% conversion and deactivate through carbon buildup. Jiao <jats:italic>et al.</jats:italic> developed a bifunctional catalyst that achieves higher conversions and avoids deactivation (see the Perspective by de Jong). A zinc-chromium oxide creates ketene intermediates that are then coupled over a zeolite. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6277" page="1065" related-article-type="in-this-issue" vol="351" xlink:href="10.1126/science.aaf1835">1065</jats:related-article> , see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6277" page="1030" related-article-type="in-this-issue" vol="351" xlink:href="10.1126/science.aaf3250">1030</jats:related-article> </jats:p>
