An alternative approach is to utilize atmospheric CO2 on-site to produce high value-added renewable fuels. However, current CO2 utilization technologies predominantly require a concentrated CO2 feed or high temperatures.<\/p>\n<p><\/p>\n<p>Herein, we report a gas-phase double-bed direct-air carbon capture and utilization flow reactor that produces syngas (CO + H2) by on-site utilization of air-captured CO2 using light, without the need for high temperature or high pressure. The reactor consists of a bed of solid silica-amine adsorbent to capture aerobic CO2 and produce CO2-free air; concentrated light is used to release the captured CO2 and convert it to syngas over a bed of silica\/alumina-titania-cobalt-bis(terpyridine) molecule semiconductor photocatalyst. As a counter reaction, we use the oxidation of depolymerized poly(ethylene terephthalate) plastic.<\/p>\n<p><\/p>\n<p>We envision that this technology will work daytime-dependent, i.e. CO2 will be captured at night&nbsp; and converted into synthesis gas under concentrated sunlight during the day.\u201d<\/p>\n<p><\/p>\n<p>Click here for the article on nature.com:&nbsp;<a
