PHOTOCATALYST COMPRISING TIO2-PORPHYRIN DERIVATIVES COMPLEX AND METHOD FOR PREPARING THE SAME

摘要

The present invention includes a complex of TiO_2 and a porphyrin derivative, and relates to a photocatalyst electrodeposited with platinum particles and a method for preparing the same. Since the photocatalyst according to the present invention includes the TiO_2-porphyrin derivative complex, light in visible region can be absorbed among the sunlight. The photocatalyst has a wide absorption band and good efficiency as a photocatalyst, and thus, can be usefully applied in producing hydrogen by decomposing water.
