Emerging new-generation covalent organic frameworks composites as green catalysts: design, synthesis and solar to fuel production

Due to structural versatility, permanent porosity, low mass densities, and exceptional stability, covalent-organic frameworks (COFs) have received great interest in green catalysis. The fruitful combination of COFs with carbonaceous materials, polymer, metal nanoparticles, and porous polymer networks results in sustainable COFs-based composites. The synthetic routes like functionalization with knots and linker coating and encapsulation methods are discussed due to affordability, non-flammable, and environment-friendly nature. The review offers the recent advances in variant categories of green COFs composites, synthesis routes, and their applications as sustainable catalyst. Mainly, we focused on the green reaction parameters, including chemical reactions under solvent-free or mild conditions, which endorses their wide-range applicability at both industrial and scientific stages. Lastly, an outlook on the ongoing challenges and prospects for the future advancement of COFs composites are presented.
