The photocatalytic activity of CoAlPO4-5 and CoAlPO4-11 were evaluated for hydrogen production via water reduction under visible irradiation. The synthesized materials were characterized thoroughly with respect to elemental analysis, XRD, SEM, FTIR, DR, BET and NH3 desorption measurement. Electrical conductivity, photo-electrochemical measurements were also studied. Since AlPO4 materials possess a unique chemical composition as well as structural and micro-morphological characteristics. The photocatalysts have shown a remarkable surface area ∼ 183 and 258 m2 g−1 which lead to a better acceleration of the charge (e-/h+) transfer by increasing the number of surface reaction sites. Under visible light, the photocatalysts exhibited a good photo-reactivity for hydrogen production with a yield of 64 and 1260 μmol g−1 min−1 for CoAlPO4-5 and CoAlPO4-11, respect...

Batch mode experiments were done using various parameters such as pH, contact time, dye concentration and thermodynamic study. First, the adsorbent was characterized using X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and ICP-MS analysis for chemical analysis. The experimental results showed that mussel shells are a mixture of 73% of calcite and 26% of aragonite with traces of aluminum, magnesium, sodium, silicium and zinc. Maximum pH was about 2 for efficient biosorption of Cr (VI). The equilibrium was attained in 120 min. The kinetic analysis showed that the pseudo-second-order model is the best fit to the experimental data. The experimental isotherm data was analyzed using Langmuir and Freundlich isotherm equations. The best fit was obtained by Freundlich model with maximum monolayer biosorption capacity of 6 mg/g. Thermodynamic study was found to be not spontaneous, endothermic. The Gibbs energy decreased with rise in temperature indicating an increase in feasibility of biosorption at higher temperature.

Density functional theoretical studies demonstrated a high electrophilicity of the starting chromones.

They may be poisoned by products of the reaction or impurities present in the monomer feed, and contain heavy metals, such as chromium, mercury, antimony, etc., that presents environmental disposal problems for the user. Maghnite is a montmorillonite sheet silicate clay that is exchanged with protons to produce Maghnite-H + (Mag-H +). This non-toxic and cheaper cationic catalyst was used for the copolymerization of ε-caprolactone (CL) with epichlorohydrin (ECH).The effects of the amounts of Mag-H + and the temperature on the synthesis of poly (ε-caprolactone-co-epichlorohydrin) were studied. Increasing Maghnite-H + proportion and temperature produced the increase in copolymerization yield. The copolymer obtained was characterized by 1 H-NMR and IR spectroscopy.
