Abstract
Abstract Photocatalytic CO 2 reduction into high‐value C 2+ products such as C 2 H 6 is of great importance but challenging due to their multi‐electron steps and high energy barrier of C─C coupling. Moreover, improving its solar‐to‐chemical (STC) energy conversion efficiency in pure water beyond the current 1% empirical value is also a significant challenge. Herein, graphite carbon nitride (g‐C 3 N 4 ) nanosheets with controllable carbon (C) doping and nitrogen (N) vacancies (PCCN‐x) are designed through a biochar‐tailored protocol for efficiently and selectively photo‐converting CO 2 into C 2 H 6 . The optimal PCCN‐10 photocatalyst enables the achievement of an exceptional C 2 H 6 activity of 99.14 µmol g −1…
