MgAl hydrotalcites, or layered double hydroxides (LDHs), with different Mg/Al molar ratios were synthesized by the coprecipitation method. The structure of solids was collapsed thermal treatment at 723 K obtaining mixed oxides high specific surface areas (264−318 m2/g). When these put in contact aqueous solutions containing 4-chlorophenol and para-cresol (80 ppm:0.62 0.73 mmol, respectively) recovered rehydration material showing named "memory effect" LDH materials. LDHs active for...
Abstract The synthesis by precipitation method of a ZnS hybrid photocatalyst functionalized with monoethanolamine in MEA-water solution for its application photocatalytic hydrogen production was investigated this research work. functionalization MEA as an organic component the greatly modified structural, textural, and optical properties ZnS. With different ratios reaction medium, these were enhanced. specific surface area is augmented up to 150 m 2 /g, exhibited response visible spectrum....

Abstract The synergy between a semiconductor, such as CdS, and an insulator, MgO, was approached to improve the photocatalytic H 2 evolution. Commercial nitrate magnesium carbonate Mg precursor of MgO were evaluated in obtaining CdS/MgO nanocomposites their activity. synthesis its photoactivity function sensitive structure. A dependence on mixture Mg(OH) phases, crystallite size [2 0 0] (D (2 0) ) crystallographic directions, cubic phase, discovered after X-ray diffraction (XRD) analyses....
BACKGROUND To overcome the drawback of low photocatalytic efficiency due to electron − hole recombination and narrow photoresponse range, a novel Bi2S3/ZrO2 composite photocatalyst was designed. The possesses wide photoabsorption up 800 nm, which occupies mostly UV visible light region. Composites were synthesized using solvothermal method. production hydrogen from methanol/water, under light, demonstrated. RESULTS A remarkable activity for obtained composites light. reported 4440 µmol h−1...
Cobalt modified TiO2 and cobalt-cerium were synthesized by sol gel technique using two different routes. In the first case material was prepared adding directly precursor of metal (Co) during sol-gel synthesis (In situ). The second one consisted in impregnation supports Ce-TiO2 with a cobalt solution (Impregnated). materials obtained characterized XRD their textural properties determined. effect as well presence cerium photocatalytic evaluated photodegradation phenol aqueous phase. According...
In this paper, phosphated-alumina prepared from boehmite and phosphoric acid (1, 4, 6 mmol of PO4(3-)) is proposed as a good alternative catalyst to obtain ecological gasoline by the reaction dimerization butenes in gas phase using flow reactor mild conditions (60 degrees C C4/C4= molar ratio = 1). XRD spectra samples showed formation gamma-alumina solids. BET specific surface area values bare alumina were not notably modified when these materials phosphate, 180-m2/g 170 m2/g. All solids are...
