Metal-free, Cu(II)- or Zn(II) tetrakis [4-(2,4-bis-(1,1-dimethylpropyl)phenoxy)]phthalocyanines loaded over TiO2 (anatase) proved to be active in the photoreduction of CO2 to formic acid (HCO2H) in water under UV–vis light. CuPc/TiO2 is catalyst of choice, allowing to reach a maximum yield of HCO2H, unequalled by any other similar catalytic systems. Because of their low environmental impact, low potential
负载在TiO 2(锐钛矿)上的无金属,四价[4-(2,4-双-(1,1-二甲基丙基)苯氧基)]酞菁的Cu(II)-或Zn(II)在光还原反应中具有活性可见光下水中的CO 2转化为甲酸(HCO 2 H)。CuPc / TiO 2是选择的催化剂,可以实现HCO 2 H的最大产率,这是任何其他类似的催化体系所无法比拟的。由于这些材料对环境的影响小,潜在成本低且能有效进行功率转换,因此在建立可持续的CO 2增值方法中显示出希望。
