Potential use of four types of fly ash waste as raw material for synthesis of photo- catalysts to be applied for wastewater treatment was investigated. In this respect the four selected fly ash types were subject to morphological characterization by dimensional analysis of particles and scanning electronic microscopy on to composition characterization by thermogravimetric analyses and X-ray fluorescence. Their potential to be used for advanced degradation of organic compounds via heterogeneous photocatalysis was investigated on a synthetic solution of methylene blue as model compound. Solutions containing methylene blue and fly ash (as catalyst) were subject to UV-VIS radiation and samples were collected at specific time intervals and were centrifuged in order to remove the fly ash. Methylene blue degradation efficiency was measured based on the adsorption at 662 nm via UV-VIS spectrophotometry. Obtained results proved the fly ash potential to be used as photo catalyst but in order to improve its degradation capability there is a need to develop new composite catalytic materials based on classic photo catalysts and fly ash.
