In this work, we report the synthesis, characterization and application of graphene oxide stabilized PdCo nanoparticles ([email protected]) for the dehydrocoupling of dimethylamine borane (DMAB) as a model reaction. Bimetallic graphene oxide stabilized PdCo nanoparticles were readily synthesized using an ultrasonic reduction technique, in which both metals of Pd and Co were reduced with GO. The dispersion of PdCo nanoparticles on the surface of GO was enhanced with the help of the ultrasonic reduction method which result in the enhancing of dispersion of both metals without any agglomeration problem. The characterization studies revealed that graphene oxide stabilized PdCo nanoparticles have a uniform, homogeneous distribution on graphene oxide and an average particle size of 3.48 ± 0.22 nm. After fully characterization of graphene oxide stabilized PdCo nanoparticles, they have been tried in model reaction as a catalyst and exhibited a high catalytic performance compared the previous catalysts in literature with a TOF value of 226.80 h⁻¹. The investigation of kinetic parameters showed that graphene oxide stabilized PdCo nanoparticles have very high negative entropy (ΔS: −170.85 J mol⁻¹ K⁻¹) value and a low activation energy value (Ea: 17.53 ± 2 kJ mol⁻¹) for the model reaction.

在这项工作中，我们报告了氧化石墨稳定的PdCo纳米颗粒（[电子邮件保护]）的合成，表征和应用，用于二甲胺硼烷（DMAB）的脱氢偶联作为模型反应。使用超声还原技术可以轻松合成双金属氧化石墨稳定的PdCo纳米颗粒，其中Pd和Co的两种金属均被GO还原。PdCo纳米颗粒在GO表面的分散度借助超声还原法得以增强，这导致两种金属的分散度均得到提高，而没有任何团聚问题。表征研究表明，氧化石墨烯稳定化的PdCo纳米颗粒在氧化石墨烯上具有均匀，均匀的分布，平均粒径为3.48±0.22 nm。^-1。动力学参数的研究表明，氧化石墨稳定的PdCo纳米粒子具有很高的负熵（ΔS：-170.85 J mol ^-1  K ^-1）值和较低的活化能值（Ea：17.53±2 kJ mol ^-1）。模型反应。
