Photocatalytic reduction of molecular oxygen is a promising route toward sustainable production hydrogen peroxide (H2O2). This challenging process requires photoactive semiconductors enabling solar energy driven generation and separation electrons holes with high charge transfer kinetics. Covalent organic frameworks (COFs) are an emerging class semiconductors, tunable at level for carrier transfer. Herein, we report two newly designed two-dimensional COFs based on (diarylamino)benzene linker...
This review deals with homogeneous and heterogeneous catalytic processes for the Guerbet condensation, as well discusses biomass sources, thermodynamics technological considerations.
UiO-66 is a promising metal-organic framework for photocatalytic applications. However, the ligand-to-metal charge transfer of an excited electron inefficient in pristine material. Herein, we assess influence missing linker defects on electronic structure and discuss their ability to improve transfer. Using new defect classification system, which transparent easily extendable, identify most photocatalysts by considering both relative stability structure. We find that properties structures...
Abstract A general synthetic strategy has been developed, which can be used for the preparation of all known as well five new functionalised UiO‐66‐X compounds [X = H, F, F 2 , Cl, Cl Br, Br I, CH 3 (CH ) CF (CF NO NH OH, (OH) OCH (CO H) SO C 6 H 4 ]. Starting from a reaction mixture ZrOCl · 8H O, BDC‐X (BDC: 1,4‐benzenedicarboxylate), formic acid and N ‐dimethylacetamide (DMA) having molar ratio 1:1:100:104.44, compounds, except UiO‐66‐CO were obtained under solvothermal conditions (150 °C,...
The stability of metal-organic frameworks (MOFs) typically decreases with an increasing number defects, limiting the defects that can be created and catalytic other applications. Herein, we use a hemilabile (Hl) linker to create up maximum six per cluster in UiO-66. We synthesized UiO-66 (Hl-UiO-66) using benzene dicarboxylate (BDC) as 4-sulfonatobenzoate (PSBA) linker. PSBA acts not only modulator but also coligand enhances resulting defective framework. Furthermore, upon postsynthetic...
A combined theoretical and experimental study is performed in order to elucidate the effects of linker functional groups on photoabsorption properties UiO-66-X materials. This study, which both mono- difunctionalized linkers (with X = OH, NH2, or SH) are investigated, aims obtain a more complete picture choice functionalization. Static time-dependent density theory calculations with molecular dynamics simulations linkers, results compared UV/vis spectra understand electronic governing...
Four highly porous covalent organic frameworks (COFs) containing pyrene units were prepared and explored for photocatalytic H2 O2 production. The experimental studies are complemented by density functional theory calculations, proving that the unit is more active production than bipyridine (diarylamino)benzene reported previously. decomposition experiments verified distribution of over a large surface area COFs plays an important role in catalytic performance. Py-Py-COF though contains other...
Rise of porous covalent triazine frameworks (CTFs) for sustainable applications.
Extensive research has been carried on the molecular adsorption in high surface area materials such as carbonaceous and MOFs well atomic bonded hydrogen metals alloys. Clathrates stand among ones to be recently suggested for storage. Although, simulations predict lower capacity than expected by DOE norms, additional benefits of clathrates low production operational cost, fully reversible reaction, environmentally benign nature, risk flammability make them one most promising explored next...
UiO-66 is regarded as an epitome of metal-organic frameworks (MOFs) because its stability. Defect engineering has been used a toolbox to alter the performance MOFs. among most widely explored MOFs capability bear high number defects without undergoing structural collapse. Several representative works in field MOF-based defect are available based on UiO-66. In this review, more emphasis given toward construction catalytic sites by including all detailed synthesis procedures for inducing...
Abstract Covalent Organic Frameworks (COFs) have recently emerged as light‐harvesting devices, well elegant heterogeneous catalysts. The combination of these two properties into a dual catalyst has not yet been explored. We report new photosensitive triazine‐based COF, decorated with single Ni sites to form catalyst. This crystalline and highly porous shows excellent catalytic performance in the visible‐light‐driven sulfur–carbon cross‐coupling reaction. Incorporation transition metal COF...
Three highly crystalline and porous COFs with promising photoredox properties have been prepared. Via a post-sulfurization process, the imine-linked were converted into thiazole-linked COFs, generating conjugated ultrastable photocatalyst for H 2 O production.
