Abstract：Rising atmospheric levels of carbon dioxide and the depletion of fossil fuel reserves raised serious concerns about the ensuing effects on the global climate and future energy supply. Utilized the abundant solar energy to convert CO2 into fuels such as methane or formic acid, which could address both problems simultaneously as well as provide a convenient means of energy stroage. In this paper, good performance of UIO-66-NH2-ZnO-Ni catalyst was obtained through vertical aligned ZnO nanosheets arrays grown on the Ni foam by constant voltage deposition method followed by UIO-66-NH2 grafted into ZnO by solvent-thermal method. It turned out that the symmetrical ZnO growed from all directions on Ni foam and then modified by UIO-66-NH2 at the surface properly from the SEM images. CO2 could be absorbed into the pores easily because of the high affinity of UIO-66-NH2 which reduced the hydrogen evolution ability successfully. The catalyst also had excellent photoelectron-catalytic reduction performance and the major product was formic acid. The highest yield of formic acid was 30.98mmol in three hours.
