This DOCTORATE position will work together with researchers of project 31. The scope of the
proposal of the project 31 of the Programme of CO2 Abatment of the RCGI
the manufacture and characterization of nano-oxides (NOx) to promote ideal conditions for the
production of organic molecules from CO2 and H2O by photocatalytic reactions. Semiconductor
oxide, surface composition and particle size of nano-oxides play a key role in creating the
conditions for absorption of light radiation, adsorption and reactions of H2O and CO2 molecules
for the production of organic molecules. The physico-chemistry of interfaces, surfaces and grain
boundaries of nano-oxides can be controlled by segregation of additives as well as particle size.
However, the bandwidth and its defects are controlled by the composition of the semiconductor,
which in turn controls the absorption of light. In this way, the production of nanoparticles with the
control of the chemical composition of the interfaces enables the reaction of the photocatalyst to
allow the photocatalytic reaction between CO2 and H2O for the production of organic products
with potential for use as fuel or raw material for the production of inputs in the oil industry.
This DOCTORATE position will work together with researchers of project 31. This position is
expected to be developed in collaboration with researchers from the Engineering Programme of
USP’s Research Centre for Gas Innovation – RCGI (summary of the program and projects is found
in the RCGI website at www.usp.br/rcgi).
The focus will be the modification of surface characteristics and energy manipulation in order to
obtain the better catalysts properties necessary for the reactions. Specific goals are: -Synthesis
and characterization of ceramic powders for use as a catalyst in artificial photosynthesis; -Project
and elaboration of a lab scale set-up. The catalyst performance and design should maximise the
The DOCTORATE candidate must have skills primarily in the following areas: materials engineering,
chemical engineering, chemistry and physics
