摘要
制备了一系列表面胺基改性的过渡金属类水滑石催化剂,采用XRD、N_2吸附、FTIR、TEM和元素分析对其进行了表征。以O_2为氧化剂,在无溶剂的条件下,考察其对一系列醇选择性氧化反应的催化性能。结果表明,所制备的改性类水滑石催化剂仍保留类水滑石载体的层状结构,而载体的元素组成显著影响其改性催化剂的性能;在较优的反应条件下,仲醇、环烷醇和芳香醇均可被选择性氧化成相应的醛或酮。
A series of surface modified hydrotalcite-like compounds were prepared and characterized by XRD,N_2adsorption-desorption,FT-IR,TEM and elemental analysis.The obtained compounds were used as catalyst for the solvent-free selective oxidation of alcohols with O_2 as oxidant.The results reviewed that the obtained surface modified catalysts still showed the good pattern characteristics of hydrotalcite.Moreover,the elemental composition of hydrotalcite-like support influenced significantly the catalytic performance of relative catalysts.Under the optimal reaction conditions,secondary alcohol,cyclanol and aromatic alcohol could be selectively oxidized to their corresponding aldehydes or ketones.
