dc.description.abstract [EN] The photocatalytic activity for benzene hydroxylation to phenol by hydrogen peroxide has been evaluated using a series of photocatalysts based on defective graphene. The series includes defective graphene containing or not Au and Cu2O nanoparticles. The latter exhibits the highest activity, but a very low phenol yield as a consequence of the occurrence of a large degree of mineralization. A considerable increase in phenol selectivity was achieved by modifying the surface of the Cu2O nanoparticles supported on defective graphene with long-chain alkanethiols. Under the optimal conditions using an octanethiol-modified Cu2O-graphene photocatalyst, a selectivity to phenol of about 64% at 30% benzene conversion was achieved. This remarkable selectivity was proposed to derive from the larger hydrophobicity of the alkanethiol-modified Cu2O-graphene photocatalyst that favors the preferential benzene adsorption versus adsorption of phenol and hydroxybenzenes. es_ES
