Abstract

ABSTRACT: To minimize the ever‐increasing global warming and environmental problems, the conversion of atmospheric CO2 into value‐added solar chemicals/fuels is one of the most challenging tasks. As a means to accomplish this, herein we have synthesized first time novel in situ selenium‐doped polyimide frameworks (Se‐PIFs) photocatalyst via thermal co‐polymerization approach between melem (M) and perylene 3, 4, 9, 10‐tetracarboxylic dianhydride (PTDA) along with selenium (Se) as a dopant. The Se‐PIFs photocatalyst shows outstanding photocatalytic stability and activity for high solar fuel production (HCOOH ~ formic acid) from CO2 . The solar light active Se‐PIFs photocatalyst was demonstrating the ~ 10‐fold higher photo‐conversion of CO2 to formic acid with yields of 250. 6 μmol. The current work is providing a facile and scalable avenue as well as sheds light on creating a new route for in situ judicious design highly efficient Se‐PIFs photocatalyst. The outcome is a benchmark instance for the use of selenium‐doped polyimide frameworks as a highly practical and efficient solar light active photocatalyst for carrying out the selective production of formic acid from environmental CO2 . Abstract : The graphic abstract depicts the NADH regeneration and formic acid (HCOOH) production from environmental CO2 using newly designed metal‐free selenium‐doped polyimide frameworks (Se‐PIFs) photocatalyst under solar light irradiation via artificial photosynthetic route. The Se‐PIFs photocatalyst is found to be more efficient for NADH regeneration and formic acid production with high yield. The produced NADH and formic acid are demonstrated the importance in many industrial and pharmaceutical applications.
