In this study a comparison of structure, morphology and adsorption capacity between copper doped natural and synthetic zeolite is investigated. Synthetic zeolite A was synthesized from natural clinoptilolite as Si source and sodium aluminate as Al source. The comparative surface characterization of both copper doped natural and synthetic zeolites has been investigated by X-ray diffraction (XRD), scanning...
Self assembled monolayer (SAM) of alkane-thiol of 6-carbon (1-hexanethiol, C6) chain length is applied on Cu surface (deposited on Si substrate) and examined carefully. Firstly, the ability of SAM adsorption onto Cu surface is confirmed by the sharp rise of water contact angle (CA) on the surface. Next, the thermal stability of SAM when it is stored in different environments is studied. The CA decreases...
A new adsorbent was developed from municipal sewage sludge (SS) combined with 5-20% pyrolusite of the weight of SS carbon, and using ZnCl2 as chemical activation reagent. Characterized by N2-BET methods and SEM, the result showed that the surface area of the new adsorbent was increased to 354.198 m2/g compared with that of the unmi- xed sludge activated carbon 232.526 m2/g and total pore and micropore...
Cu2O nanorods with extraordinary large surface area are synthesized by polyol method successfully. Their photocatalytic property is evaluated by the photodegradation of brilliant red dye under visible light irradiation. For comparison, Cu2O nanocubes are synthesized and evaluated with photocatalytic property as well. The results show that the photocatalytic activity of the Cu2O nanorods is more than...
