Abstract:

The main aim of the NANOARHITECT is to consolidate a research team and an independent research program focused on the design and development of multifunctional core@void@shell nanoarchitectures towards visible light dual-functional photocatalysis. Besides the general objective, NANOARHITECT will smoothly run along the route defined in this two-fold strategy of sustainable hydrogen production accompanied by the oxidative degradation of pharmaceutical drugs pollutants in a single process, achieving all defined targets and eventually going further based on the following specific objectives: (SO1) development of fundamental materials based on the synergistic combination of different types of hierarchical-like Al;Rh;La:SrTiO3/Cc (Cc: FeOOH, NiOOH and FexNi1-xOOH) composite core entrapped in SiO2 matrix to generate innovative core@void@shell nanoarchitectures with enhanced visible light adsorption, highly effective active sites exposed and optimized mass transport to (SO2) acquire of fundamental knowledge around dual-functional photocatalysis by boosting the photocatalytic activity in all dimensions. Filling two-goals-with-one-action, NANOARHITECT will lay the foundations on a unique opportunity to firstly develop these innovative techniques from the ground up in an ambitious project such as this to inspire new approaches on old problems in photocatalysis with expected research outputs that will make a positive contribution to the European excellence research area.

Abstract:

The overarching objective of the VAL1D project is to demonstrate and validate at TRL-4 the innovative active carbon to incorporate photocatalyticnanomaterials, with modified morphologies after azo dye adsorption, that is able to sustain both adsorptive and photocatalytic processes, as they can destroy any organic materials, including the organic matrix from hospital WWTPs. While the concept of single component nanomaterials, including one particular type of inorganic oxide NPs such as NiFe2O4, has been already reported and used in photocatalytic activities at lab scale, VAL1D target is to go a step further, through the combinations between semiconductor oxides and active carbon (AC) for bringing up further active surface area and include additional functionalities for recovery of photocatalysts.

Abstract:

Project will be continuation of research conducted in the previous period, in project PD2016-1510/02.05.2018 led by the director of this proposal, devoted to full exploitation of 3D photocatalysts for water remediation and splitting.

There are bottlenecks of water splitting and water decontamination among which are the stability of materials, fast recombinations of charges (e.g. reduce efficiency) that took place in semiconductor materials, band gap limitations of different semiconductors with respect to water redox potentials, etc. The Revolution3D project offer solutions to resolve these bottlenecks by generating new knowledge on photocatalytic materials and processes through developing new routes for synthesis, advanced concepts for nanostructuring of semiconductors, and discovery of novel semiconductors including nanocomposites. The overall aim of the project is to develop different 3D heterostructures(3D-Het) based on oxyhydroxides (γ-FeOOH, γ-NiOOH, β-CoOOH) coupled to a novel double perovskite,Sr2AlTiO6, determine their optoelectronic properties and charge/energy transfer mechanisms and establish their potential as photocatalysts, particularly for hydrogen production. Moreover, Revolution3D project specifically aims to tailor interfacial charge and energy transfer processes by means of chemical functionalisation and evaluate them with photochemical and transient spectroscopy, as well as explore the effect of the oxyhydroxide nanoparticles as co-catalysts, which stabilise smaller double perovskite semiconductor particles, reduce agglomeration that will result in larger accessible surface areas and allow the use of solar energy to activate the process.

Abstract:

Last decades brought a considerable development of technologies based on ordered systems. Starting with semiconductor physics and photovoltaics, technologies soon evolved towards the utilisation on large scale of thin films and of surface / interface properties. Example go nowadays from data storage and readout (electrostatic or magnetic memories, giant magnetoresistance) to catalysis, gas sensors or photocatalysis (surface phenomena), and towards interfaces with biological matter (biosensors, templates for tissue reconstruction, interfaces between biological electrical signals and microelectronics). In Romania, crystal growth is performed since half a century; nevertheless, during the last years these activities fade out and need to be seriously reinforced, especially with the advent of new laser and detector technologies required by the Extreme Light Infrastructure facilities. Also, surface science started to be developped seriously only during the last decade, together with techniques involving self-organized nanoparticles, nanoparticle production etc. The main goal of this Project is to gather the relevant experience from the five partners, namely the experience in crystal growth from the University of Timișoara, with the surface science, nanoparticle and nanowire technologies developped by NI of Materials Physics, the cryogenic and ultrahigh vacuum techniques provided by the NI for Cryogenic and Isotopic Technologie, and the experience in ordered 2D systems (graphene and the like) owned by the NI for Microtechnologies (IMT). This common agenda will result in a coherent fostering of technologies relying on ordered systems of variable dimensionalities: 0D i.e. clusters or nanoparticles, including quantum dots; 1D i.e. free and supported nanowires and nanofibers; 2D: surfaces, interfaces and graphene-like systems; and 3D crystals of actual technological interest, together with setting up new ultrahigh vacuum, surface science and electron spectroscopy techniques.
