Effect of Nitrogen Doping in GO as Support in ZnO/GO-N Compounds and Their Photocatalytic Assessment to Degrade the Lignin Molecule

Control of the recombination process and improvement transport charge carriers could be achieved in photocatalysts by modifying catalytic support. In present study, our goal was to study effect nitrogen doping on graphene oxide sheets using sources such as urea, thiourea, or ethylenediamine produce GO-N supports which were used form ZnO/GO-N systems. The synthesis ZnO carried out through a hydrothermal under microwave heating. compounds tested degradation lignin molecule UV irradiation. A set characterization techniques compounds, including XPS analyses confirmed N-doping samples. compound reached 40% 70 min, while produced 79% degradation, also min evidencing positive best results obtained when thiourea media.
