Infrared Light-Driven CO2 Overall Splitting at Room Temperature
10.1016/j.joule.2018.02.019 2018-03-20 To date, infrared (IR) light constituting almost 50% of the solar energy has never been utilized, owing to an insurmountable contradiction between IR light utilization and CO2photoreduction. To break through this limitation, we designed an ultrathin intermedi... |
