Abstract: 

The purpose of this research is to remove greenhouse gases CO2 and CH4 by using ZnO nanoparticles produced from aqueous solution of zinc acetate dihydrate and ethanol by sonochemical method, and comparison of its performance with commercial ZnO. The prepared ZnO nanoparticles were analyzed by XRD, UV-vis, FTIR and SEM. Also, the photocatalytic conversion of CO2 and CH4, and photoreduction products were identified by means of GC-TCD and FTIR in gas medium. SEM images indicated that prepared ZnO nanoparticles were uniform. UV-vis spectrum showed that, after calcination, the range of ZnO absorption was proceeding toward the visible region. Also, XRD spectrum showed that, after calcination, pure ZnO has been produced. According to the results, nano ZnO with the efficiency about twice of commercial ZnO, leads to conversion of 14.3 and 14.7 % for CO2 and CH4, respectively.
