Hybrid photo-thermal-catalytic reforming of methanol was investigated by Cu/TiO₂ nanocatalysts. The obtained results indicated that methanol conversion (150 °C) was remarkably increased by congruent roles of the photo and thermal catalysis (about 36% in the presence of light). To gain further insight into this effect, the semiconductor properties of TiO₂ nanoparticles were modified with dopants (Ce, La, Sm and Zn). Cyclic voltammetry was also adopted as a mean of studying the semiconductor properties of these doped TiO₂ nanoparticles. The reactor tests of these Cu/doped-TiO₂ nanocatalysts confirm that their activity and selectivity are highly dependent on the semiconductor properties and surface defects of TiO₂ nanoparticles. Accordingly, the CO₂ selectivity depends on the surface defects of TiO₂ and Al₂O₃/TiO₂ support with the high surface defects improves the CO₂ selectivity by about 99.9%.

研究了Cu / TiO ₂纳米催化剂的杂化光热催化重整。获得的结果表明，光和热催化的一致作用（在有光的情况下约为36％）显着提高了甲醇转化率（150°C）。为了进一步了解这种效应，用掺杂剂（Ce，La，Sm和Zn）修饰了TiO ₂纳米颗粒的半导体性能。还采用循环伏安法作为研究这些掺杂的TiO ₂纳米颗粒的半导体性能的手段。这些Cu /掺杂的TiO ₂纳米催化剂的反应器测试证实，它们的活性和选择性高度依赖于TiO ₂的半导体性质和表面缺陷。纳米粒子。因此，CO _2的选择性取决于TiO ₂和Al ₂ O ₃ / TiO ₂载体的表面缺陷，具有高的表面缺陷使CO _2的选择性提高了约99.9％。
