| 摘 要： | 利用太阳能光催化还原CO2和H2O到燃料和化学品是一条极具吸引力但又充满挑战性的转化途径.迄今为止,只有非常有限的光催化剂已经被报道可以在可见光照射下光催化还原CO2.局部表面等离子体共振(LSPR)现象可以被用作一种有效的开发可见光催化剂的策略.贵金属Au,Ag,Pt等的LSPR现象已经被较为广泛的研究,并应用于光催化、光热、气敏等多种领域.而低价态金属自掺杂的金属氧化物,如MoO3-x和WO3-x,也被证明具有LSPR现象,可用于开发更加廉价的可见光催化剂.本文通过简单的溶剂热法成功合成了低价态Mo自掺杂的MoO3-x纳米片催化剂,并在合成过程中原位加入TiO2纳米颗粒(TiO2-NP)和TiO2纳米棒(TiO2-NT),构建了MoO3-x-TiO2纳米复合物.电镜表征显示,MoO3-x-TiO

| Abstract: | The photocatalytic reduction of CO2 with H2O to fuels and chemicals using solar energy is one of the most attractive but highly difficult routes.Thus far,only a very limited number of photocatalysts has been reported to be capable of catalyzing the photocatalytic reduction of CO2 under visible light.The utilization of the localized surface plasmon resonance(LSPR)phenomenon is an attractive strategy for developing visible-light photocatalysts.Herein,we have succeeded in synthesizing plasmonic MoO3?x-TiO2 nanocomposites with tunable LSPR by a simple solvothermal method.The well-structured nanocomposite containing two-dimensional(2D)molybdenum oxide(MoO3?x)nanosheets and one-dimensional(1D)titanium oxide nanotubes(TiO2-NT)showed LSPR absorption band in the visible-light region,and the incorporation of TiO2-NT significantly enhanced the LSPR absorption band.The MoO3?x-TiO2-NT nanocomposite is promising for application in the photocatalytic reduction of CO2 with H2O under visible light irradiation. |
