                 摘要:采用溶剂热法在增透的多孔玻璃表面制备负载非晶态有机锆聚合物,通过 SEM、XRD、BET、FTIR、
                 UV-Vis、ICP、有机元素分析、荧光光谱(PL)及紫外光电子能谱(UPS)等手段对样品进行了表征。结果表明,
                 非晶态有机锆聚合物(2.64 eV)具有比 NH 2 -UiO-66(Zr)(2.74 eV)更窄的带隙,复合速率较慢的光生电子-空穴对。

                 Abstract: Glass slide immobilized amorphous organozirconium polymer was fabricated by solvethermal
                 method. The sample was characterized by SEM, XRD, BET, FTIR, UV-Vis, ICP, organic element analysis,
                 fluorescence  spectroscopy  (PL)  and  ultraviolet  photoelectron  spectroscopy  (UPS).  The  results  showed
                 amorphous  organozirconium  polymer  had  a  narrower  band-gap  width (2.64 eV) than  NH 2-UiO-66(Zr)
                 powder  (2.74  eV).  Additionally,  amorphous  organozirconium  exhibited  slow  recombination  rate  of
                 photogenerated  electron-hole  pairs.  Two  pieces  of  glass  slides  loaded  with  amorphous  organozirconium
                                                         2
                 were glued together with a total area of 50.4 cm to use in the photocatalytic synthesis of methanol from
                 CO 2. The reaction was illuminated under a 300 W Xe lamp for 4 h. The yield of methanol was 443.0 μmol,
                                                                   –1
                 and the corresponding turnover frequency (TOF) was 8.69 h . While 0.1 g NH 2-UiO-66(Zr) was used as
                 catalyst under the same reaction conditions, the yield of methanol was 244.3 μmol, and the TOF was only
                      –1
                 0.17 h . Therefore, the photocatalytic performance of amorphous organozirconium polymer is obviously
                 better than that of NH 2-UiO-66(Zr) powder and shows good cyclic stability.
