The effect of catalyst preparation method and metal precursors on the catalyst basicity were studied in Pd catalysts supported on magnetic SBA-15 for benzyl alcohol oxidation (BzOH) to benzaldehyde (BzH). The reaction was carried out in an environmentally friendly condition, i.e, in the absence of additive and solvent, at low temperature (95 °C) in the presence of oxygen. Various techniques such as ball milling and impregnation as well as different precursors such as nitrate and chloride of palladium were applied for catalyst preparation. Among them, MPM-2 catalyst which was prepared by nitrate precursor and physical hand mixing, exhibited the most optimized basicity. The intensity of 2.9 × 10⁻¹⁰ of total basicity was measured by CO₂-TPD experiment. The catalysts showed 50 % of BzOH conversion and 95 % of selectivity towards BzH after 3.5 h. The activation energy of the reaction was significantly decreased and reached 17.6 kJ.mol^-1.

在磁性SBA-15上负载的Pd催化剂上研究了催化剂的制备方法和金属前驱体对碱度的影响，该Pd催化剂用于苯甲醇氧化（BzOH）成苯甲醛（BzH）。该反应在环境友好的条件下，即在不存在添加剂和溶剂的情况下，在低温（95°C），氧气存在下进行。各种技术，例如球磨和浸渍，以及不同的前体，例如钯的硝酸盐和氯化物，都用于制备催化剂。其中，通过硝酸盐前体和物理手工混合制备的MPM-2催化剂具有最优化的碱度。通过CO ₂测量总碱度的强度2.9×10 ^-10-TPD实验。在3.5小时后，催化剂显示出50％的BzOH转化率和95％的BzH选择性。反应的活化能明显降低，达到17.6 kJ.mol ^-1。
