Abstract(s)
There is a need for technological innovation in the water sector worldwide, as a result of the growing
demand for water supplies – meeting increasingly restricted quality criteria, while coping with the
increasing scarcity of clean water sources1. Under this context, the use of treated wastewater as an
alternative water source has emerged as a topic of high priority2. However, meeting current quality
requirements for wastewater reuse is a great challenge, in which nanotechnology holds a great
potential1.
Catalytic wet peroxide oxidation (CWPO) is a promising water/wastewater treatment technology; it
enables the formation of highly oxidizing hydroxyl radicals (HO•) under atmospheric pressure and
low to moderate temperatures, when a suitable catalyst is employed for the decomposition of
hydrogen peroxide (H2O2)3. However, further improvement of catalyst design is still required in order
to allow the scale-up of the CWPO technology towards real-scale applications.
Bearing this in mind, our work has been focused on the development of highly active and stable
hybrid magnetic carbon nanocomposites for CWPO. A detailed catalyst design at the nanoscale, based
on the understanding of the surface reactions and interactions involved in the CWPO process, has
recently allowed us to move forward towards the treatment of a real industrial wastewater with high
pollutant load – collected from a mechanical biological treatment (MBT) plant for municipal solid
waste processing. This communication reports the findings obtained in the last four years by our
research group in this quest. A particular emphasis is given to the synergistic effects arising from the
combination of iron-based catalysts with the easily tuned properties of carbon-based materials.
