Different nanoparticles like cobalt oxide (Co3O4), iron oxide (Fe3O4), manganese ferrite (MnFe2O4), gadolinium oxide (Gd2O3), cerium oxide (CeO2), iron-cobalt (FeCo) and iron-cerium (FeCe) were prepared and tested for their catalytic activity in the liquid phase oxidation of benzyl alcohol (BzOH) to benzaldehyde (BzH) in a self-designed Pyrex glass Gas Blowing Rotating Reactor (GBR reactor). Textural properties such as size and shape of catalysts were studied through available characterization techniques for better understanding of their catalytic activity. The oxidation of BzOH was carried out in different solvents such as water, toluene, benzene and heptane to unveil the effect of thermal conductivity of solvent on the catalytic activity of nanoparticles. The reaction was also carried out in solvent-free conditions in the presence of O2. The efficiency of each catalyst was measured in term of productivity (mmol g−1 h−1) instead of conventional units. The productivity values in comparison to available reports revealed that these catalysts will be prospective alternative to conventional industrial catalysts.

导热系数与纳米颗粒催化活性的关系:苯甲醇的氧化

不同的纳米颗粒,例如氧化钴(Co 3 O 4),氧化铁(Fe 3 O 4),铁氧体锰(MnFe 2 O 4),氧化ado(Gd 2 O 3),氧化铈(CeO 2),制备了铁钴(FeCo)和铁铈(FeCe),并在自行设计的Pyrex玻璃吹气旋转反应器中测试了苄醇(BzOH)液相氧化为苯甲醛(BzH)的催化活性。 (GBR反应器)。通过可用的表征技术研究了诸如催化剂的尺寸和形状的质地特性,以更好地理解其催化活性。BzOH的氧化反应在不同的溶剂(例如水,甲苯,苯和庚烷)中进行,以揭示溶剂的导热性对纳米颗粒催化活性的影响。该反应也在O 2的存在下在无溶剂条件下进行。以生产率(mmol g -1  h )衡量每种催化剂的效率-1)代替常规单位。与现有报告相比的生产率值表明,这些催化剂将有望替代常规工业催化剂。
