A magnetic N-doped graphene photocatalyst for fast tetracycline degradation DataSet

This material can rapidly degrade tetracycline in aqueous solution under visible light irradiation. Scanning electron microscopy shows that the material has a folded sheet-like graphene structure, and a large number of nanoparticles are observed on the graphene sheets.

Raman spectroscopy indicates the presence of significant defects in the material, which can suppress the recombination of photo generated electron hole pairs. The performance and degradation mechanism of the photocatalyst were verified through a series of optical and electrochemical experiments as well as theoretical calculations. The photocatalyst achieved a degradation efficiency of 97.1% for tetracycline within two hours under visible light irradiation, which is superior to other reported photocatalysts.
