| 摘 要： | 以水热反应法制备了ZrW2O7(OH)2(H2O)2粉体,利用TG-DTA、XRD、DRS和BET等手段对其理化性能进行表征,并考察了其在紫外光照射下分别以CH3OH为电子给体和以AgNO3为电子受体时的光解水产氢产氧性能.结果表明:制备的样品为结晶良好且晶相单一的四方相ZrW2O7(OH)2(H2O)2粉体,吸收边为310nm,带隙值为3.9eV,比表面积为5.9m2/g.在以CH3OH为电子给体的条件下,0.3wt%Pt/ZrW2O7(OH)2(H2O)2的光解水产氢平均速率为3.7μmol/h,以AgNO3为电子受体的条件下ZrW2O7(OH)2(H2O)2的产氧平均速率为27.8μmol/h.本研究表明,包含OH基的ZrW2O7(OH)2(H2O)2具有光解水产氢产氧能力,能带结构符合光解水要求,是一种新型的光解水材料.

| Abstract: | ZrW_2O_7(OH)_2(H_2O)_2 powder was prepared by a hydrothermal reaction method and its thermal decomposition property,crystal structure,photon absorption property and specific surface area were characterized by TG-DTA,XRD,DRS and BET,respectively.Its photocatalytic activity for H2 and O2 evolution from water splitting under UV light irradiation was examined in the presence of CH3OH as electron donor and AgNO3 as electron scavenger.The results show that ZrW_2O_7(OH)_2(H_2O)_2 is crystallized well in tetragonal... |
