Alcohols are naturally occurring substances that are mainly used to prepare aldehydes through oxidation/dehydrogenation processes (such as coupling transfer dehydrogenation reactions), where unsaturated organic compounds are used as an oxidants. In the industrial field, various homogeneous and heterogeneous catalysts are used for the oxidation of alcohols and the formation of aldehydes in a short period of time, greater chemical conversion, high yields and higher selectivity. In this work, silica and ceria nanoparticles have been synthesized by sol–gel and co-precipitation methods, where silica is used as a support material for catalytically active nano-sized ceria. Catalyst calcined at 600 °C and characterized by FT-IR, TEM, SEM and XRD was used for liquid-phase oxidation of primary alcohols. Maximum percentage conversion with high selectivity of octanol to octanal was obtained at 60 °C in 1 h with respect to 0.5 g catalytic dose. In the presence of a heterogeneous catalyst, the percentage conversion and selectivity of octanol to octanal was found to increase over time.

醇是天然存在的物质，主要用于通过氧化/脱氢过程（例如偶联转移脱氢反应）制备醛，其中不饱和有机化合物用作氧化剂。在工业领域中，各种均相和非均相催化剂用于在短时间内氧化醇和形成醛，更高的化学转化率，高产率和更高的选择性。在这项工作中，通过溶胶-凝胶法和共沉淀法合成了二氧化硅和二氧化铈纳米颗粒，其中二氧化硅被用作具有催化活性的纳米级二氧化铈的载体材料。在600°C下煅烧并通过FT-IR，TEM，SEM和XRD表征的催化剂用于伯醇的液相氧化。相对于0.5 g催化剂量，在60°C的条件下，在1小时内可获得辛醇对辛醇的高选择性的最大转化率。发现在非均相催化剂的存在下，辛醇转化为辛醇的百分比转化率和选择性随时间增加。
