, () , (), (). . , () . : , , . It was shown that the treatment using ethylene glycol increases the quantum yield of reaction of anthracene photooxidation catalyzed with tetraphenilporphirin (TPP), immobilized on perfluorinated sulfocationic membranes (PSM), in more than two times. The treatment with ethylene glycol resulted to nano-structural alterations in PSM, which was confirmed by X-ray diffraction data. Structural alterations in PSM resulted in ethylene glycol treatment were interpreted as an increasing of the space between polymeric bilayers and as an increasing the dispersion of the space, that resulted to increasing of the water interlayers (nano-caves) thickness in PSM. Key words: membranes, nano-structure, porphyrins, photocatalysis.
