Light-Mediated Sustainable Conversion of Carbon Dioxide to Valuable Methanol by Highly Efficient Covalent Organic Framework g-C₃N₄ Composites as a Reusable Photocatalyst

Abstract

A novel triazine-based structured two-dimensional (2D) covalent organic framework (COF), known as TRITER-1, has been prepared through the Schiff-base condensation reaction between terephthalaldehyde and 1,3,5-tris(4-aminophenyl)triazine. Additionally, g-C 3 N 4 has been incorporated within imine-based covalent organic frameworks to produce the composite

Utility of silver nanoparticles embedded on a covalent organic framework as a highly active catalyst for carboxylative cyclization with CO2: a sustainable route for production of tetronic acids and oxazolidinones

“…In the last few decades, several homogeneous and heterogeneous catalysts such as organocatalysts, alkali metal-based catalysts, transitions metal-based catalysts, and ionic liquid catalysts have been developed to serve this purpose. 11–21 Homogeneous catalysts, such as metal complexes and organocatalysts, have been shown to enhance the reaction efficiency and selectivity for CO 2 fixation reactions. However, heterogeneous catalysts offer several advantages over homogeneous catalysts in chemical reactions.…”
