| Popis: | ZnMn2O4 flower-like microspheres self-assembled by curved nanoplates are synthesized by calcining the ZnMn2-ptcda MOF precursors. These curved nanoplates consist of small particles with controlled particle size. The band gap of the ZnMn2O4 microspheres is increased to about 2.1–2.6 eV. The enlarged specific surface areas, porosity and decreased particle size are also investigated in details. Owing to the self-assemble mesoporous nanostructure, the photocatalytic performance on reduction of CO2 into CO is enhanced significantly for ZnMn2O4 flower-like microspheres, compared with ZnMn2O4 nanoparticles. This suggests that ZnMn2O4 flower-like microsphere can be regarded as a promising photocatalyst for photo-reduction, photo-degradation and photosynthesis. |
