IN COLLABORATION WITH
Thanks to the collaboration with several participants (including University of Salento, BOSH and ItalCementi), the objective of the project was to develop photo-catalysts conveniently engineered and to operate the synthesis of colloidal nano-crystals based on Titanium (Ti) and Tungsten (W) with controlled morphology and composition.
- Research of bottom-up synthesis approaches for the development of photo-catalysts able to activate deNOx processes: Selective photo-catalytic reduction of NOx to N2, photo-catalytic oxidation of NOx to HNO3, decomposition of NO into N2 + O2.
- Investigation of chemical processes in solutions for the growth of nano-crystal oxides with specific properties.
- Optimisation of nanoparticles surface chemicals, specifically by employing TiO2 nanoparticles for photo-catalysis through reaction with phosphate ions, thanks to the study of stabilising copping agents.
- Planning and realisation of pilot plants to operate the industrial synthesis of colloidal nanomaterials (CNPs) for applications in construction and automotive sectors.
- Development of measurement system to create a index for the photo-catalytic abatement of NOx.
- Formulation and development of mortar compounds based on photo-catalytic ligands to be employed in the construction industry.
- Definition of optimal advanced methodologies for the reverse engineering of floor pans and catalytic converters, with researches and simulations.
- Realisation of photo-catalytic converter prototypes.
- Development of diagnostic methods to investigate the stability and toxicity of photo-catalytic materials for applications in the construction and automotive industries.
- Functionalisation with first base coupled with phosphoric acid results better in terms of photo-catalysis effectiveness compared to H3PO4 functionalisation, especially for NOx abatement.
- As per the photo-catalysis tests conducted in water with different PH conditions during the project, materials functionalised with phosphoric ions have been found to be less sensible to PH conditions, highlighting the possible use in concrete compounds. The protocol shows interesting potentiality to make this process scalable.
- Comprehension of surface chemical properties of Titanium nanaparticles is fundamental for the optimisation of their photo-catalytic activities.
- The developed deposit methodology can be considered effective, reproducible and easily scalable. Also, this methodology does not need the use of carcinogenic solvents, nor high temperatures.
Development of innovative solutions focused on heat transfer efficiency of solar thermal power plant.
- Acquisition of knowledge and research about innovative nano-engineered heat transfer fluids based on metal oxides for CSP solar energy production plants.
- Acquisition of knowledge and research about CO2 Dissociation process and production of Hydrogen through solar energy by employing Cerium oxides (CeO2) nanopowders as thermo-catalyst.
- Realization of pilot industrial plant for production of nano-engineered powders and heat transfer nanofluids.
- Investigation on Chemical Synthesis and physical-chemical characterization with nanoparticles of Copper Oxide (CuO), Aluminium Oxide (AI2O3), Cerium Oxide (CeO2). The synthesis of AI2O3, CeO2 and CuO nanoparticles using a precipitation method is influenced by the temperature which alter the dimension and shape of nanoparticles. The PH of the solution influences the reaction performance of AI2O3 nanoparticles and the presence of oxygen influences CeO2 nanoparticles.
- Development of the production plant for the engineering and tests of CuO, AI2O3 and CeO2 nanoparticles.
- Copper Oxide Nanoparticles: X –Ray analysis of nanoparticles generated by TCT shows pure CuO. TEM analysis of nanoparticles shows their dimension of 5-10 nm as APS. The morphology of nanoparticles is identified as spherical.
- Aluminium Oxide Nanoparticles: X-Ray analysis shows pure AI2O3. Thermal treatment at 1150°C is necessary to achieve Corundum phase. The Debay – Sherrer calculation shows APS is 105 nm.
- Cerium Oxide Nanoparticles: X-ray analysis shows nanoparticles dimension of 9.3 nm. TEM analysis show the cubic form of nanocrystals. Further morphology depends on the reaction conditions which are being currently investigated.
- Heat Transfer Nanofluid test for engines cooling showed a fuel consumption reduction for high efficiency marine engine, higher performance and reliability of the racing engine, size reduction of the radiator in racing engine at constant heat transfer capability, size and cost reduction of the radiator in automotive engine at constant heat transfer capability.
Rise in volume fraction of CuO nanoparticles shows a relevant rise in thermal conductivity capability of the water and a higher percentage of CuO in the fluid would probably reduce the stability of the nano-fluid due to the tendency of clusterisation.
- Nanofluid formulation influences the stability of the suspension and in particular the nanoparticles size and the pH of the fluid. Mechanical treatment of the nanofluid in terms of grinding methodology is relevant to achieve the stability of the suspension.
The project is aimed at developing of a laboratory specialised in the research of innovative technical solutions for the realisation of high-temperature solar energy production plants to produce electricity directly from thermodynamic cycles and to produce hydrogen combustibles indirectly from thermo-chemical processes.
- Investigation of management costs to develop and maintain solar energy production plants of small dimensions for residential and SME use (250-2500 m2).
- Evaluation of innovative methods for optimisation and specialisation of solar dish power plants and receivers.
- Research of technologies for enhancements in energy production performance and equipments working life.
- Development of high performance heat transfer nano-engineered fluids.
- Optimisation of direct electrical energy production at higher temperatures (up to 800 degrees Celsius) with single thermodynamic cycles and combined cycles for the production of hydrogen combustibles through reversible and non-reversible thermo-chemical processes.
- Research of thermal accumulators for small transistors and chemical reactions.
- Development of technologies for the production of electricity from renewable sources and reduction of pollutants emissions in power generation processes.
