Porous BiOBr/Bi₂MoO₆ Heterostructures for Highly Selective Adsorption of Methylene Blue.

ABSTRACT: Porous BiOBr/Bi₂MoO₆ (Br/Mo) heterostructures were designed and successfully fabricated, in which BiOBr nanoparticles were deposited on the surface of the secondary nanoplate of three-dimensional porous Bi₂MoO₆ architectures through a deposition-precipitation process. The as-prepared Br/Mo heterostructures were used as an adsorbent to remove methylene blue (MB) from aqueous solution. The batch adsorption results indicated that 50.0 wt % Br/Mo heterostructures show an enhanced adsorption capacity compared with pure Bi₂MoO₆ and BiOBr. The effects of initial solution, initial concentration, and contact time were systematically investigated. The optimum adsorbent amount and the pH value were determined to be 0.8 g L^-1
