Abstract Organic photochemistry is intensely developed in the 1980s, which nature of excited electronic states and energy electron transfer processes are thoroughly studied finally well‐understood. This knowledge from molecular organic can be transferred to design covalent frameworks (COFs) as active visible‐light photocatalysts. COFs constitute a new class crystalline porous materials with substantial application potentials. Featured outstanding structural tunability, large porosity, high surface area, excellent stability, unique photoelectronic properties, potential candidates various research areas (e.g., photocatalysis). review aims provide state‐of‐the‐art insights into COF photocatalysts (pristine, functionalized, hybrid COFs) for transformations. The catalytic reaction mechanism COF‐based influence dimensionality crystallinity on heterogenous photocatalysis performance also discussed, followed by perspectives prospects main challenges opportunities future

Covalent Organic Frameworks for Photocatalytic Hydrogen Peroxide Generation

ACS Materials Letters, Год журнала: 2024, Номер 6(5), С. 2007 - 2049

Опубликована: Апрель 17, 2024

Hydrogen peroxide (H2O2), a valuable chemical, is widely used as powerful oxidizing agent in chemical synthesis, pharmaceuticals, medical disinfection, and environmental treatment industries. Currently, over 95% of H2O2 produced industrially using the anthraquinone process, which associated with its high energy consumption hazardous byproducts. Therefore, photochemical synthesis from water oxygen covalent organic framework based photocatalysts have attracted considerable attention. This review aims to outline recent achievements, challenges future prospects COFs heterogeneous for sustainable generation. We summarize chronological development COFs, different mechanisms involved, detailed experiments quantification methods photocatalytic The puts forward an outlook, highlighting advantages limitations anticipate that this will provide insight into current progress inspire next-generation production.

In this article, the mesoporous silica framework of KIT‐6 was synthesized and, then its surface modified using 3‐aminopropyltrimethoxysilane (APTMS). The new KIT‐6@DABP@Cu nanocatalyst prepared by anchoring copper complex on KIT‐6. identified several techniques, including FT‐IR, WDX, AAS, SEM, TGA, XRD, EDS, and BET. physical properties, such as size, shape, morphology were studied SEM analysis. elemental composition described wavelength dispersive X‐ray spectroscopy (WDX) EDS. FT‐IR used to characterize functional groups in structure nanoparticles. stability TGA at high temperatures. Also, area, total volume, average diameter pores determined Brunauer–Emmett–Teller (BET) catalyst found be a new, highly effective, green for synthesizing 5‐substituted‐tetrazoles nitriles sodium azide (NaN 3 ) catalyzed polyethyleneglycol‐400 (PEG‐400) solvent. This heterogeneous showed good recyclability up five consecutive cycles without notable loss catalytic efficiency.
