Abstract
Addressed herein, a highly active and stable nanohybrid has been synthesized for hydrogen production. The newly prepared nanocatalysts are silica-based palladium-cobalt nanohybrid structures (PdCo@SiO2 nanohybrid) (3.82 ± 0.37 nm). The prepared nanohybrids were fully identified with the help of different analytical techniques such as UV-Vis (Ultraviolet-Visible spectroscopy), XPS (X-ray photoelectron spectroscopy), TEM (Transmission electron microscopy), XRD (X-ray diffraction) and HR-TEM (High-resolution transmission electron microscopy) analyses. This prepared nanohybrid was quite successful in the production of hydrogen from DMAB in ambient conditions (TOF: 108.27 h−1). By the way, it was observed that the DMAB was converted entirely to the product at room temperature with the help of PdCo@SiO2 nanohybrid. Moreover, monodisperse PdCo@SiO2 nanohybrid has shown outstanding reusability performance even after 4th usage in the same reaction. As a result, it can be said that the prepared nanohybrid is highly efficient, stable and durable nanocatalyst for the dehydrocoupling of dimethylamine-borane.
