Abstract :
Graphite and graphene oxides have been studied amply in the last decade, due to their diverse properties and
possible applications. Recently, their functionality as photocatalytic materials in water splitting was reported.
Research in these materials is increasing due to their band gap values around 1.8-4 eV, and therefore, these are
comparable with other photocatalysts currently used in heterogeneous photocatalytic processes. Thus, this research
reports the photocatalytic effectiveness of graphite oxide (GO) and graphene oxide (GEO) in the degradation of
4-chlorophenol (4-CP) in water. Under the conditions defined for this research, 92 and 97% of 4-CP were degraded
with GO and GEO respectively, also 97% of total organic carbon was removed. In addition, by-products of 4-CP that
produce a yellow solution obtained only using photolysis are eliminated by photocatalyst process with GO and
GEO. The degradation of 4-CP was monitored by UV-Vis spectroscopy, High Performance Liquid Chromatography
(HPLC) and Chemical Oxygen Demand (COD). Thus, photocatalytic activity to remove 4-CP from water employing
GO and GEO without doping is successfully showed, and therefore, a new gate in research for these materials is opened.
