{[Bi(BTC)(H 2 O) 2 ]·H 2 O} n (H 3 BTC = 1,3,5-benzenetricarboxylic acid) was synthesized by an eco-friendly hydrothermal method and characterized by single-crystal X-ray diffraction, IR and UV/Vis spectroscopy, photoluminescence (PL), and thermogravimetric analyses. The complex featured a 3D metal-organic framework with Bi 2 secondary building units. In the complex, the central Bi 3+ is ninecoordinate, three central Bi atoms and three BTC 3anions are interconnected into a ring with the dimension of 7.95 ϫ 9.89 Å 2 . Moreover, the

A magnetic yeast-assisted composite Y-La0.7Sr0.3MnO3/TiO2with p–n heterojunction was prepared. And it shows an obvious synergistic photocatalytic effect on methyl orange (MO) wastewater under solar irradiation.
