Article Synopsis
- The study developed oxygenated graphene nanosheets (OGNs) through an electrochemical exfoliation method and examined their ability to remove methylene blue (MB) from water.
- The characterization of OGNs was conducted using various techniques, revealing a structure rich in functional groups that enhance dye removal through electrostatic interactions.
- The maximum adsorption capacity for MB was found to be 476.19 mg/g, indicating OGNs could be a highly effective material for wastewater treatment applications focused on color removal.
We herein present an alternative geometry of nanostructured carbon cathode capable of obtaining a low turn-on field, and both stable and high current densities. This cathode geometry consisted of a micro-hollow array on planar carbon nanostructures engineered by femtosecond laser. The micro-hollow geometry provides a larger edge area for achieving a lower turn-on field of 0.

Herein, a composite of graphene decorated with manganese oxide nanoparticles was prepared via PEP from a KMnO solution and graphite electrode under a voltage of 70 V in an ambient environment. By controlling the initial KMnO concentration, we obtained distinct MnO/graphene samples.
