Understanding CeO2-Supported Nanostructures: In Situ / Operando Studies of Model Catalysts (GAČR)

In this project, we propose to use the unique combination of two such state-of-the-art experimental techniques: near-ambient-pressure X-ray photoelectron spectroscopy (NAP-XPS) and near-ambient-pressure scanning probe microscopy (NAP-SPM) to probe four industrially important catalytic reactions in operando conditions (CO oxidation, water-gas shift, methane decomposition and steam reforming). Cerium oxide supported Pt and Au nanoclusters will serve as the model systems that will be studied before,...

Hydrophilic polymer interaction with nanostructured cerium oxide towards biomedical applications (GAČR)

Cerium oxide nanoparticles (CNPs) are receiving much attention as a potential antioxidant agent in medicine since their possibility to regenerate the initial oxidation state through redox reactions. However, the role of hydrophilic coating on CNPs in mediating the reaction between reactive oxygen species and the cerium oxide surface is not fully characterized. This proposal aims at narrowing the gap between fundamental knowledge of polymer interaction with cerium oxide under operando conditions...

Novel materials for proton exchange membrane water electrolyzers (GAČR)

The project deals with preparation, thorough characterization and testing of novel nanostructured materials and catalysts for use in proton exchange membrane water electrolyzers. Catalysts will be designed with emphasis on reducing the noble metal loading without significant performance drop. We will approach the task from two different directions: i) We will study new high-surface catalyst supports in order to enlarge the active area of catalyst. ii ) We will focus on creating mixed, multi-elemental...

Detection mechanisms on chemiresistors with a sensitive layer based on nanostructured oxides (GAČR)

[Finished] The project aims at preparation of nanostructured oxidic materials (SnO2, WO3, ZnO a In2O3), intended for sensitive layers of chemiresistors, and study of surface reactions taking place during the detection of selected classes of gaseous analytes (oxidizing gases - O2, NO2; reducing gases - H2, CH4; gases/vapours that can form hydrogen bonds with oxidic surface - H2O, NH3; unsaturated hydrocarbons; alcohols and ketones) on these layers. In the framework of the project a new...

Development of thin-film catalyst with low noble metal content for unitized regenerative fuel cells (TAČR)

[Finished] Most developed countries are increasingly utilizing renewable energy (i.e. solar and wind). One of the obstacles that has to be overcome is the volatility of generated power that usually does not meet the immediate consumption characteristics. Possible solution is to convert overproduced electricity to hydrogen via proton exchange membrane water electrolyzers (PEMWE) and subsequently during windless days or during nights the stored hydrogen would be converted back to electricity by means of...
