Abstract
Porous materials based on metal-organic framework MIL-100(Fe) and diatomite were synthesized. Composites possess specific surface area of 322 and 441 m2/g and hierarchical porous structure with broad pores of diatomite and narrow pores of MIL-100(Fe) particles. Influence of synthesis strategy on structure of materials and their catalytic properties in photocatalytic degradation of phenol was investigated. Composite obtained with preliminary wet impregnation of iron nitrate solution show predominant formation of MIL-100(Fe) particles inside the pores of diatomite. Materials demonstrate catalytic activity in phenol degradation by photo-Fenton process. Composite synthesized without preliminary wet impregnation displays highest catalytic activity with predominant formation of MIL-100(Fe) particles on external surface of diatomite.
