Abstract:
... In this work, carbon-coated mixed-phase (tetragonal/orthorhombic) SnO₂ photocatalysts were successfully fabricated with a chemical precipitation method, followed by a facile hydrothermal process. This material exhibits the highest activity during photocatalytic methyl orange and phenol degradation, and the degradation rate constant is almost 3 times than that of pure tetragonal SnO₂. The enhanceme ...

Abstract:
... Ca₂V₂O₇, Sr₂V₂O₇, and Ba₂V₂O₇ pyro-vanadates were synthesized using a modified chemical precipitation method and annealing. Detailed crystal structure, morphology, electronic structure and optical properties were investigated by XRD, UV-visible absorption, FTIR, Raman, FE-SEM, XANES, and photoluminescence spectroscopy. Rietveld refinement on the XRD patterns of Ca₂V₂O₇, Sr₂V₂O₇, and Ba₂V₂O₇ has co ...

Abstract:
... A series of visible-light-induced 2D/2D layered g-C₃N₄/Bi₁₂O₁₇Cl₂ composite photocatalysts were successfully synthesized by a one step chemical precipitation method with g-C₃N₄, BiCl₃ and NaOH as the precursors at room temperature and characterized through XRD, FTIR, XPS, TEM, BET and UV-vis DRS measurements. The results of XRD, FTIR and XPS indicated that g-C₃N₄ has been introduced in the Bi₁₂O₁₇ ...

Abstract:
... Herein, two kinds of nano-hydroxyapatite were synthesized from Clam and Magellan shell by wet chemical precipitation method. Mainly, carboxymethyl cellulose/acrylamide/nano-hydroxyapatite composite hydrogels were developed via a free-radical polymerization process and investigated as a sorbent for Acid Blue 113 (AB) from aqueous AB solution. The swelled and kinetic behaviours of hydrogels were inv ...
