Sunlight sparks spectacular C(sp³)-H bond arylation: Rod shape ACC@MeF composite shines bright in 2,4-dinitrophenylhydrazine reaction

Abstract

The solar light responsive selective C(sp³)-H bond activation by photocatalytic pathway using graphene platform as photocatalyst is a green and sustainable route to achieve value added chemicals on gram scale synthesis. Graphene has low activity due to fast recombination charges, band gap suitability problems, and inefficient solar light absorption ability. Therefore, activated carbon cloth- based nitrogen-rich phenolic resin was developed from melem and formalde hyde. The ACC@MeF light harvesting composite demonstrates outstanding light-harvesting capability, leading to enhanced photocatalytic performance in C(sp3)-H bond formation, suitability of band gap, high molar extinction coefficient and high thermal stability. The development of metalfree activated carbon cloth based melem formaldehyde resin for the solar light photocatalytic transformation of organic compounds is anticipated to have broad reaching applications.
