Three coordination polymers based on the V-shaped 4,4’-dicarboxybiphenyl sulfone (H2sdba) ligands, [Zn3(μ-OH)2(sdba)2]n·2nH2O 1, [Zn2(sdba)2(4,4’-bipy)]n·2
We investigated the photocatalytic degradation of dye wastewater by using titanium dioxide (TiO2) coated on a coal cinder. The coal cinder was used as the carri
