Oxidic nanomaterials offered and still promise real, effective and efficient innovation in strategic sectors for mankind (energy production and use, sustainable development, environment protection and restoration, healthcare practices and systems). However, in particular for TiO2 nanomaterials, a complete comprehension of the phenomena involved at molecular and atomic level is hindered by the wide heterogeneity of:
types of TiO2‐based nanoparticles (NPs) developed, each of them often exhibiting a rich dimensional and morphological variety,
A set of NPs with controlled size and shape and high stability, obtained though reproducible synthetic methods, can be the basis of calibration standards and certified reference materials in nanometrology.
The objectives of WP1 will be to deliver DESIGN RULES for synthesis procedures based on
and laser ablation (LA) on liquid
routes capable to generate sets of TiO2 nanoparticles with controlled size, shape and surface properties. The achievement of the target is based on the definition of proper values of synthesis parameters such as temperature, pH, feeder material, mineraliser, presence of shape controllers, size of droplets formed in the microemulsion, surfactant-precursor/solvent ratio.
Interactions with WP2 (to guide the experiments by state-of-the-art experimental design methods, and in the case of the HT preparation method, also by ad-hoc developed thermodynamic and multiscale models) and WP4 (to define the properties of NPs at nanometer and molecular level) in feedback loops are fundamental to achieved the pursued objectives.
The general objective is the evolution of TiO2 NPs synthetic procedures form a “trial and error” approach to a knowledge basedc one for predictively engineered nanoparticles
