Abstract:

PolyEnzIM main scope is to obtain cross-linked polyelectrolyte/enzyme architectures onto sand microparticle surfaces with potential application in water cleaning by sorption and static/dynamic catalytic degradation of organic dissolved pollutants. PolyEnzIM propose a new and innovative method for core-shell composite materials, environmental friendly, with high sorption capacity for organic pollutants (dyes, drugs, bisfenol A) and subsequent transformation of these in less toxic compounds, inert or complete degraded under the immobilized enzyme influence. The components: sand, polyelectrolytes (polycations/polyanions) and enzymes (catalase, laccase, and peroxidase) will be assembled by a new and innovative technique: one step deposition by direct precipitation of binary or ternary nonstoichiometric complex in-situ formed followed by subsequent cross-linking for organic shell stabilization around each sand particles. The core-shell sand/(polycation/enzyme) composites will contain a high number of functional groups for pollutants sorption and enough enzyme amounts for subsequent catalytic degradation of pollutant molecules. PolyEnzIM project aims to reduce the production costs by using inexpensive sand and time synthesis by one-step deposition of all components onto solid surface due the great adhesion properties of the used polyanions. Dissemination: 5 articles submitted to ISI journals, participation at 6 international/national conferences.

Abstract:

Project will will combine the main scientific results obtained by the PL and his team in various national and international projects for the full exploitation of innovative 3D nanoreactors for water remediation and splitting. The GHOST3D project aims to design, develop, investigate and control of novel photocatalytic nanoreactors with higher efficiencies exploiting a wider portion of sunlight. The advantage of the GHOST3D concept is that the component nanomaterials could be considered as independent tools which can be easily combined for the efficient production of new photocatalytic nanoreactors with different configurations. Based on these, the overall aim of the GHOST3D project is devoted to go far beyond state of the art through full exploitation of core/shell@void@shell 3D nanoreactors (e.q. Al:SrTiO3/Fe2O3@Void@SiO2) based on tuning morphologies, oxyhydroxide phase transitions, compositions, utility and functionality of their nano-constituent building units to match the activity – selectivity demands of photocatalytic applications. The GHOST3D project will combine fragmentary efforts in photocatalysis with the aim to advance the state-of-the-art and to launch a methodology that will ensure the development of viable, efficient and innovative 3D nano-heterostructure photocatalysts. The achievements that will be reached in GHOST3D will allow the progress beyond of the state-of-the-art in the field of 3D assembly of nanostructured building blocks into complex architectures

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.

Hydrogen evolution and advanced water treatment using innovative 3D heterostructure photocatalysts Call name: P 1 - SP 1.1 - Proiecte de cercetare pentru stimularea tinerelor echipe independente

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.
