Abstract

A kind of molybdenum and copper compound, CuMoO4, was prepared by a hydrothermal method.

Fabrication of UiO-66/MIL-101(Fe) binary MOF/carboxylated-GO composite for adsorptive removal of methylene blue dye from aqueous solutions

“…A known dose of UiO-66/ MIL-101(Fe)-GOCOOH composite (0.001-0.03 g) was added to MB dye (50 to 300 mg L À1 ). pH optimization (3)(4)(5)(6)(7)(8)(9)(10)(11) was adjusted using 0.01 M of NaOH and/or 0.01 M of HCl. The adsorption process was conducted at various temperatures (25-55 C) under constant agitation rate (250 rpm).…”

“…For instance, methylene blue (MB) dye is mostly utilized for coloring cotton, wood and silk, but its discharge into water bodies even in low concentration leads to various harmful impacts such as eye burning, vomiting, cyanosis, convulsions, tachycardia and methemoglobinemia. 3,5 Accordingly, several techniques have been applied for dye removal such as advanced oxidation, 6 membrane separation, 7 electrolysis, 8 catalytic reduction, 9,10 photocatalytic degradation, 11 occulation. 12 Other than the mentioned techniques, visible light-driven photocatalysis and adsorption methods are considered the most promising technologies in the environmental remediation eld owing to their high efficiencies, low cost, minimal harmful by-products and their low energy consumption.…”

Mechanochemical NaCl–Mediated Synthesis of Porous CuxMo1–xOy Catalyst for Knoevenagel Condensation

“…To optimize the application performance of molybdate-based materials, several synthetic methods have been well-developed, such as hydrothermal methods, , coprecipitation methods, sonochemical methods, and combustion methods. , However, the obtained molybdates usually possess unsatisfactory specific surface area, such as 5 m 2 /g via combustion-like methods, <1 m 2 /g via hydrothermal methods, and 11 m 2 /g via coprecipitation methods. In recent years, many innovative methods have also been reported for the preparation of molybdate catalysts.…”

Photocatalytic Transformations of 1H-Benzotriazole and Benzotriazole Derivates

“…The most used compounds of this class are 1H-benzotriazole (BTz) and tolyltriazole (a mixture of 4-methyl-and 5-methyl-1H-benzotriazole, TTz). These chemicals show strong complexing properties and are used as anticorrosive agents in cooling, hydraulic, and antifreezing fluids; moreover, they are additives in different from titanium dioxide have been proposed for the same aim (e.g., CuMoO 4 [27] and BiOI [28] under visible light and BiOBr under simulated solar irradiation [29]).…”

“…Moreover, TiO 2 functionalized with magnetic activated carbon (Fe II Fe 2 III O 4 @C) [ 25 ] and Cu-modified nanoporous TiO 2 [ 26 ] were both proposed for the removal of BTz from aqueous phase under irradiation. Alternatively, semiconductors different from titanium dioxide have been proposed for the same aim (e.g., CuMoO 4 [ 27 ] and BiOI [ 28 ] under visible light and BiOBr under simulated solar irradiation [ 29 ]).…”
