摘要:
利用Cu的有机骨架材料(Cu-MOF(CuBTC))中金属离子高度有序的特性,基于高比表面的介孔TiO2载体,通过煅烧前驱体CuBTC-TiO2复合物制备纳米负载型CuO-TiO2催化剂。使用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X线衍射仪(XRD)、N2吸附-脱附、X线光电子能谱仪(XPS)和紫外-可见光吸收光谱仪(UV-Vis)对催化剂的形貌和结构进行表征,并以甲醇-水体系为气相光催化产氢评价体系。结果表明:通过MOF前驱法制备的CuO-TiO2催化剂,平均产氢速率达到0.32 mmol/(g·h),在多次循环实验中产氢速率没有明显下降趋势,稳定性较好,明显优于通过沉积沉淀法制备的CuO-TiO2催化剂。
Abstract:
Based on the highly ordered Cu nodes well dispersed in Cu-containing metal-organic frameworks(Cu-MOF(CuBTC)),CuO-TiO2 catalyst by the calcination of CuBTC-TiO2,supported on the mesoporous TiO2 with high surface area was prepared.The catalyst was characterized by scanning electron microscope(SEM),transmission electron microscopy(TEM),X-ray powder diffraction(XRD),N2 adsorption-desorption analysis,X-ray photoelectron spectroscopy(XPS), and UV-visible absorption spectrum(UV-Vis).Methanol aqueous solution was used as an evaluation system for gas-phase photocatalytic hydrogen production.Results showed that the CuO-TiO2 catalyst prepared by MOF precursor method achieved higher hydrogen yield about 0.32 mmol/(g·h)and better stability compared with that prepared by deposition precipitation.
