A novel PdNPs/SBA-NH₂-LA catalyst has been prepared by a post-synthetic grafting approach via successive anchoring of propylamine (SBA-NH₂) and lipoic acid (SBA-NH₂-LA) functional groups followed by palladium nanoparticles immobilization. The Physico-chemical properties of the catalyst were extensively investigated by XRD, N₂ adsorption-desorption, XPS, FT-IR, and TEM analysis. The PdNPs/SBA-NH₂-LA catalyst is found to be highly selective for the hydrogenation of CC double bonds of α, β-unsaturated carbonyl compounds. Excellent conversion (95–99 %) and selectivity (>99 %) with high turn over frequency (330−1065 h⁻¹) achieved at room temperature under atmospheric hydrogen pressure within 30−90 min of reaction time. This kind of high activity is expected from its structural and textural integrity of the catalyst.

通过连续接枝丙胺（SBA-NH ₂）和硫辛酸（SBA-NH ₂ -LA）官能团，然后固定钯纳米粒子，通过后合成接枝方法制备了新型PdNPs / SBA-NH ₂ -LA催化剂。。通过XRD，N ₂吸附-解吸，XPS，FT-IR和TEM分析广泛研究了催化剂的理化性质。发现PdNPs / SBA-NH ₂ -LA催化剂对于α，β-不饱和羰基化合物的CC双键的氢化具有高度选择性。出色的转化率（95–99％）和选择性（> 99％），具有高翻转频率（330-1065 h ^-1）是在室温和大气压氢气下，在30-90分钟的反应时间内达到的。从催化剂的结构和质地完整性可以预期这种高活性。
