Zinc oxide (ZnO) nanoparticles prepared using simple co-precipitation method are characterized and photocatalytic activity is tested on the degradation of methylene blue and rhodamine B organic pollutants. Morphological and structural properties of synthesized nanomaterial have been characterized using FESEM, EDAX spectroscopy, and XRD, while UV-visible DRS spectroscopy and photoluminescence have been used to understand their optical properties. The photocatalytic behaviour of synthesized nanoparticles was evaluated on the degradation of methylene blue (MB) and rhodamine B (RhB) organic pollutants under solar light irradiation. The highest degradation was achieved for MB (100%) over RhB (96%). Preliminary investigation shows the effective degradation of organic pollutants by ZnO nanoparticles.

Abstract Heterogeneous photocatalysts was a promising material for removing organic pollutants. Titanium dioxide (TiO2) was a suitable photocatalyst for its cost efficiency and high stability to reduce various pollutants. Enhancing TiO2 photocatalyst performance by doping with changed metals or non-metal ions and organic compounds have been reviewed. These methods could enhance photoelectrochemical activity via: (i) by a donor of electrons via electron-donor agents that would produce particular defects in TiO2 structure and capture transporters of charge; (ii) by reducing recombination rate of the charge transporters and increasing degradation of pollutants. This study investigates the modification approaches of TiO2 that comprise methods for overcoming the essential TiO2 restrictions and enhancing the photocatalytic degradation of organic pollutants. Consequently, it emphasized on the current progress of modified-TiO2 used for different pollutants in ambient conditions. Amendment techniques, such as inorganic and organic parts as doping, are studied. The reported experimental results obtained with the photocatalytic oxidation process for degrading organic pollutants were also collected and assessed.
