چکیده مقاله :
The continuous increase in the combustion of hydrocarbon fuels along with the high levels of carbon dioxide emission has led to the global energy crisis and environmental changes. Photocatalyst-based methods are an effective way to deal with this energy and environmental crisis. Solar energy, which is a clean and renewable energy, is a very desirable path for photocatalytic conversion of CO2 into value-added products to deal with energy and environmental problems. Synthesis of various products such as: CH4, CO, EtOH, CH3OH and so on through the photocatalytic reduction of CO2 has been expanded. Among these products, methanol is one of the most important and widely used chemicals that are widely used in industry and in daily life [1,2]. In this paper, novel metal-organic framework nanocomposite (UiO-66/ZIF-67) will be investigated for CO2 reduction to methanol under ultraviolet/visible (UV/Vis) light irradiation at room temperature. UiO-66 & ZIF-67 have been used due to their suitable specific surface area, high thermal and chemical stability. The trueness of the nanocomposite synthesis was determined using XRD, FT-IR, FESEM, TEM, N2 adsorption-desorption, EDS, PL spectroscopy and DRS analyses. The area obtained from the analysis BET is 647.83 (m2.g-1), which shows the efficiency of the catalyst .Finally, using the desired nanocomposite, photocatalytic tests were performed under ultraviolet irradiation and in different environments, and the results are as follows(table)
