We cordially invite you to the Scientific Session dedicated to the memory of Prof. Zdzisław Pająk, which will take place on November 7, 2019 in the lecture room of the NanoBioMedical Center, AMU, from 9:00 to 14:00
Highly performing photocatalytic surfaces are nowadays highly desirable in energy fields, mainly due to their applicability as photo water‐splitting electrodes. One of the current challenges in this field is the production of highly controllable and efficient photoactive surfaces on many substrates. Atomic layer deposition has allowed the deposition of photoactive TiO2 layers over wide range of materials and surfaces. However, nitrogen doping of the growing layers, a highly effective way of controlling the absorption edges of photoactive surfaced, is still a challenging task. Here, the preparation of hierarchical nanostructured surfaces based on Langmuir–Schaefer and atomic layer deposition is proposed. Ultrathin TiO2 layers that are photoelectrochemically active in water splitting are prepared by a relatively low‐temperature catalytic decomposition of oleic acid capping layers of iron oxide nanoparticles and the posterior nitrogen adsorption. The results evidence that simple N‐adsorption is sufficient to narrow the bandgap of TiO2 layers that is equal to bandgap narrowing (0.12 eV) observed for substitutionally N‐doped materials. The photocatalytic activity tests of the prepared surfaces in water‐splitting applications demonstrate ≈90% increase in the activity of the N‐adsorbing TiO2 layers.
This Special Issue is related to the NanoTech Poland 2020, the 11th international conference, organized by the NanoBioMedical Centre, Adam Mickiewicz University Poznan, which will be held on 3–6 June 2020 in Poznań.
The PhD student will be involved in the synthesis of polymer nanoparticles, their functionalization and coating with cell membranes. These nanoparticles will then be used in biological experiments including cellular uptake analysis and assessment of cell viability after chemo and photothermaltherapy.
Preparation of ultrathin iron oxide, sulfide and nitride films on single crystal supports under ultra-high vacuum and studies of structure, electronic, catalytic and magnetic properties of the prepared nanostructures.
