“…Among these dioxins, dibenzofurans (CDFs) and polychlorinated dibenzo- p -dioxins (PCDDs) are frequently employed organic pollutants that have acute effects on living organisms. Mainly, the compound 2,3,7,8-tetrachlorodibenzo- p -dioxin (TCDD) belongs to the subclass of PCDFs and PCDDs that is considered more toxic and can enter living organisms via direct intake from drinking water . As per the findings of the US Environmental Protection Agency (EPA), TCDD is the most utilized and toxic among all dioxins.…”

The continuous rise in atmospheric CO 2 concentration, overconsumption of energy resources, and release of extraordinary organic pollutants are challenging issues of the modern era. Catalytic technology offers a promising solution to tackle these energy and environmental challenges in parallel by facilitating highly effective and sustainable processes. Herein, we report the fabrication of a series of different nature polyarylimide (PAI)-based covalent−organic frameworks (COFs) via the polycondensation reaction by altering linkers, organic solvents, and other experimental conditions. To optimize their catalytic performance, the resultant PAI-COFs were further decorated with metal−organic frameworks (ZIF-67). The decoration of COF4 with ZIF-67 led to adjusted bandgaps, created an active site, enhanced charge separation and migration of photoexcited electron−hole (e−h) pairs, extended the light absorption to the visible region, and also facilitated the transferring of electrons between the COFs and MOFs via the photoelectron modulation approach. Based on our findings, it is confirmed that COF4 and ZIF-67 (MOFs) are the optimal catalysts compared to the other COFs (COF1, COF2, and COF3) and MOFs (ZIF-8). Interestingly, compared to the pristine COF4, the 5ZIF-67/COF4 nanohybrid revealed ∼8-fold and ∼5.3-fold for CO 2 conversion, direct CO 2 capturing, and photoelectrochemical CO 2 conversion with a faradaic efficiency of 50%. Likewise, the as-fabricated catalyst also exhibits exceptional activities for photocatalytic hydrogen production and pollutant oxidation. Ultimately, this work will provide a roadmap for the design and fabrication of COF-based nanohybrids for energy and environmental applications.
