Your library or personal account may give you access

Abstract

We created an ultra-thin film photocatalytic light absorber (UFPLA) with 2~22-nm-thick TiO2 films. The UFPLA structure conquered the intrinsic trade-off between optical absorption and charge carrier extraction efficiency and therefore boosted CO2 reduction efficiency.
