| Abstract: | Herein we report an in situ synthesis of Prussian blue nanoparticles (PB) on graphdiyne oxide (GDYO) which acts as an excellent substrate. The hybrid was then used as an electrode with high electrochemical catalytic activity towards hydrogen peroxide. The PB/GDYO hybrid was prepared by simply adding FeCl3 to GDYO solution, and then mixing with Fe(CN)63 ? at room temperature. The GDYO was able to anchor PB in nanoparticle form and stabilize it in neutral and weakly basic solutions. The hybrid was investigated by transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and electrochemical measurements. The PB/GDYO hybrid showed high electrochemical catalytic activity and stability for the detection of hydrogen peroxide. |
