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 formaldehyde. 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 metal-free activated carbon cloth-based melem formaldehyde resin for the solar light photocatalytic transformation of organic compounds is anticipated to have broad-reaching applications. © 2024 Vietnam Academy of Science and Technology and Wiley-VCH GmbH.
