AB  - Rapid growth of human population has led to increased water demand by various industries and production of large amount of wastewater. Textile, leather, paper, and plastics industries wastewater, which contains organic pollutants such as dyes, needs a proper treatment in order to be safely discharged into the environment, therefore, new methods are being developed. This research is based on investigation of photocatalytic degradation of an azo-type dye Congo Red (CR) by using powdered UiO-66 type MOF (Metal Organic Framework), activated carbon (AC) and their composite powder mixtures made with different MOF/AC ratios. Additionally, this research includes investigation of renewability of these materials in several experimental cycles. Experiments were performed in batch conditions, samples were exposed to solar light irradiation, then centrifuged to remove solid particles and in order to determine the concentration of the remaining dye, solutions were analyzed by UV-ViS spectrophotometer. Renewability of the photocatalysts used in experiments was investigated by repeating this process three times, with catalysts dried at 50 °C between cycles. Results have shown that pure MOF has excellent and almost identical photocatalytical efficiency in every cycle, compared to all MOF/AC composites and pure AC, probably due to the saturation of available adsorption sites in AC. CR removal efficiency and renewability of various composites depends on MOF/AC ratio, therefore, the most efficient composites are the ones where MOF content varies from 25 wt. % up to 100 wt. %. Samples with MOF content 50 - 100 wt. % have shown excellent renewability, while composites where AC is more dominant (95 - 100 wt. %) have shown almost none. Among the composites examined in this paper, the one with MOF/AC ratio of 50/50 has shown the best cost/performance ratio in removal of Congo red dye from aqueous solution.
