As one of the best sustainable approaches for visible-light production hydrogen (H2) to meet energy demands, semiconductor-based photocatalysis has received broad interest in recent decades. The fundamental restrictions graphitic carbon nitride (g-C3N4) as a promising metal-free photocatalytic semiconductor water splitting, like insufficient harvesting and high electron–hole (e/h) pairs recombination, have limited its applications this goal. In regard, optical, charge separation, surface features g-C3N4 can be tuned via engineering C/N vacancies, which is reviewed here splitting by g-C3N4. Reports confirm that enhanced resulting from vacancies are helpful adsorption on surface, improving water-splitting kinetics. First Review, improvements structural optical characteristics introducing especially nitrogen will discussed illustrate better performance. Then, various strategies creating controlling reviewed. critical roles optimizing performance also described, finally advances defective oxidation addressed.

Copper-Based Metal–Organic Frameworks (MOFs) as an Emerging Catalytic Framework for Click Chemistry

Catalysts, Год журнала: 2023, Номер 13(1), С. 130 - 130

Опубликована: Янв. 6, 2023

In the extensive terrain of catalytic procedures for synthesis organic molecules, metal–organic frameworks (MOFs) as heterogenous catalysts have been investigated in a variety chemical processes, including Friedel–Crafts reactions, condensation oxidations, and coupling utilized owing to their specific properties such high porosity, tuneability, extraordinary activity, recyclability. The eminent copper-tailored MOF materials can be exceptionally dynamic regioselective click reactions (1,3-dipolar cycloaddition reaction). Considering fact that Cu(I)-catalyzed alkyne–azide (CuAAC) catalyzed by several other copper Cu (II)-β-cyclodextrin, Cu(OAc)2, Fe3O4@SiO2, picolinimidoamide–Cu(II) complex, Cu(II) porphyrin graphene, sorption reusability, well density copper-MOFs, open an efficient robust pathway regimented catalysis this reaction. This review provides comprehensive description analysis relevant literature on utilization Cu-MOFs CuAAC ‘click’ published past decade.

Textile effluents pose a massive threat to the aquatic environment, so, sustainable approaches for environmentally friendly multifunctional remediation methods degradation are still challenge. In this study, composites consisting of bismuth oxyhalide nanoparticles, specifically oxychloride (BiOCl) nanoplatelets, and lignin-based biochar were synthesized following one-step hydrolysis synthesis. The simultaneous photocatalytic adsorptive efficiency Biochar-BiOCl studied removal benchmark azo anionic dye, methyl orange dye (MO). influence various parameters (such as catalyst dosage, initial concentration, pH) on photo-assisted was carried out optimized using Box-Behnken Design RSM. physicochemical properties nanomaterials characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, diffraction, thermogravimetric analysis, nitrogen sorption, UV-Vis diffuse reflectance spectroscopy (DRS). maximum observed at dosage 1.39 g/L, an concentration 41.8 mg/L, pH 3.15. experiment performed under conditions resulted in 100% MO after 60 min light exposure. incorporation activated had positive impact performance BiOCl photocatalyst removing due favorable changes surface morphology, optical absorption, specific area hence dispersion photo-active nanoparticles leading more active sites. This study is within frames design development green-oriented low cost advanced (waste)water treatment applications.
