A researcher from Shahid Rajaee Teacher Training University, in cooperation with researchers from the University of Manchester and University of Antwerp, has succeeded in presenting a model to grow palladium nanofibers between graphene oxide layers in order to make energy storage devices.

According to an ISCA report, Dr. Mehdi Neek-Amal in collaboration with researchers from The University of Manchester and University of Antwerp showed that the electrochemical deposition of palladium (Pd) between graphene oxide (GO) sheets result in the self-limiting growth of 5-nm-thick Pd nanosheets.

Based on the research, “Self-Limiting Growth of Two-Dimensional Palladium between Graphene Oxide Layers,” released in Nano Letters journal, the ability of different materials to display self-limiting growth has recently attracted an enormous amount of attention because of the importance of nanoscale materials in applications for catalysis, energy conversion, (opto) electronics, and so forth.

In this research, the self-limiting growth is found to be a consequence of the strong interaction of Pd with the confining GO sheets, which results in the bulk growth of Pd being energetically unfavorable for larger thicknesses.

Furthermore, researchers have successfully carried out liquid exfoliation of the resulting Pd-GO laminates to isolate Pd nanosheets and have demonstrated their high efficiency in continuous flow catalysis and electrocatalysis.
