Both polyoxometalates (POMs) and metalloporphyrins exhibit high Arial. 9 efficiency. In this work, we designed two new composite catalysts with [5,10,15,20-tetra-(4-carboxylphenyl)-porphyrinato]-ferric chloride (FeTCPP) and H3PW12O40 (PW12)/H3PMo12O40 (PMo12), forming FeTCPP-PW12 and FeTCPP-PMo12 composite catalysts. The diameter of the catalyst particles was controlled by varying the dosage of the two reactants. The synthesis method of the catalysts is simple to operate and it can be obtained by ordinary precipitation after dissolution. Furthermore, the catalysts exhibited satisfactory activity and stability under the condition of repetitive tests. Our findings showed that phenol was almost completely degraded in 10 min under photocatalytic conditions catalyzed by the FeTCPP-PMo12 photocatalyst. This work provides new concepts for developing new types of materials for environmental applications.
