Photoelectrochemical (PEC) methods, however, lag behind their electrochemical counterparts in terms of current density. In this work, we demonstrate that, by using concentrated sunlight, we can achieve current densities similar to electrochemical methods, but with lower energy input. Specifically, we combined the direct PEC oxidation of glycerol with the dark hydrogen evolution or CO 2 reduction in a membrane-separated continuous-flow PEC cell. We achieved over 110 mA cm −2 photocurrent density, which is at least an order of magnitude larger than those typically reported in the literature. We demonstrated that the product distribution of glycerol oxidation is notably different in PEC and electrochemical scenarios at the same current density, and the parasitic oxygen evolution reaction can be suppressed in the PEC case. This approach raises opportunities to drive complex electrochemical reactions in a more selective manner.}, year = {2024}, eissn = {2520-1158}, orcid-numbers = {Samu, Gergely Ferenc/0000-0002-3239-9154; Janáky, Csaba/0000-0001-5965-5173} } @article{MTMT:34823504, title = {Stable Operation of Paired CO2 Reduction/Glycerol Oxidation at High Current Density}, url = {https://m2.mtmt.hu/api/publication/34823504}, author = {Kormányos, Attila and Szirmai, Adrienn and Endrődi, Balázs and Janáky, Csaba}, doi = {10.1021/acscatal.3c05952}, journal-iso = {ACS CATAL}, journal = {ACS CATALYSIS}, volume = {14}, unique-id = {34823504}, issn = {2155-5435}, year = {2024}, eissn = {2155-5435}, pages = {6503-6512}, orcid-numbers = {Endrődi, Balázs/0000-0003-3237-9222; Janáky, Csaba/0000-0001-5965-5173} } @article{MTMT:34725884, title = {Temperature Dependent Carrier Dynamics in Ga-Alloyed CdSe/ZnS Core–Shell Quantum Dots}, url = {https://m2.mtmt.hu/api/publication/34725884}, author = {Trényi-Sárosi, Krisztina and Tuinenga, Christopher and Samu, Gergely Ferenc and Mogyorósi, Károly and Dudás, Júlia Rita and Tóth, Bálint and Jójárt, Péter and Gilicze, Barnabás and Seres, Imre and Bengery, Zsolt Gábor and Janáky, Csaba and Chikán, Viktor}, doi = {10.1021/acs.jpcc.3c04689}, journal-iso = {J PHYS CHEM C}, journal = {JOURNAL OF PHYSICAL CHEMISTRY C}, volume = {128}, unique-id = {34725884}, issn = {1932-7447}, year = {2024}, eissn = {1932-7455}, pages = {3815-3823}, orcid-numbers = {Samu, Gergely Ferenc/0000-0002-3239-9154; Jójárt, Péter/0000-0002-5161-2723; Janáky, Csaba/0000-0001-5965-5173; Chikán, Viktor/0000-0002-4157-3556} } @article{MTMT:34688798, title = {Effect of Single-Crystal TiO 2 /Perovskite Band Alignment on the Kinetics of Electron Extraction}, url = {https://m2.mtmt.hu/api/publication/34688798}, author = {Chen, Xiangtian and Pasanen, Hannu P. and Khan, Ramsha and Tkachenko, Nikolai V. and Janáky, Csaba and Samu, Gergely Ferenc}, doi = {10.1021/acs.jpclett.3c03536}, journal-iso = {J PHYS CHEM LETT}, journal = {JOURNAL OF PHYSICAL CHEMISTRY LETTERS}, volume = {15}, unique-id = {34688798}, issn = {1948-7185}, year = {2024}, pages = {2057-2065}, orcid-numbers = {Pasanen, Hannu P./0000-0002-7237-2677; Khan, Ramsha/0000-0002-0861-597X; Tkachenko, Nikolai V./0000-0002-8504-2335; Janáky, Csaba/0000-0001-5965-5173; Samu, Gergely Ferenc/0000-0002-3239-9154} } @article{MTMT:34528348, title = {Au-decorated Sb 2 Se 3 photocathodes for solar-driven CO 2 reduction}, url = {https://m2.mtmt.hu/api/publication/34528348}, author = {Dela Cruz, John Mark Christian and Balog, Ádám and Tóth, Péter Sándor and Bencsik, Gábor and Samu, Gergely Ferenc and Janáky, Csaba}, doi = {10.1039/D3EY00222E}, journal-iso = {EES.

Unlike other technologies, low temperature electrolyzers have the ability to directly convert CO2 into a range of value‐added chemicals. To make them commercially viable, however, device efficiency and durability must be increased. Although their design is similar to more mature water electrolyzers and fuel cells, new cell concepts and components are needed. Due to the complexity of the system, singular component optimization is common. As a result, the component interplay is often overlooked. The influence of Fe‐species clearly shows that the cell must be considered holistically during optimization, to avoid future issues due to component interference or cross‐contamination. Fe‐impurities are ubiquitous, and their influence on single components is well‐researched. The activity of non‐noble anodes has been increased through the deliberate addition of iron. At the same time, however, Fe‐species accelerate cathode and membrane degradation. Here, we interpret literature on single components to gain an understanding of how Fe‐species influence low temperature CO2 electrolyzers holistically. The role of Fe‐species serves to highlight the need for considerations regarding component interplay in general.}, keywords = {DEGRADATION; CONTAMINATION; Electrolysis; CO2RR; Fe-Effect}, year = {2024}, eissn = {1521-3773}, orcid-numbers = {Endrődi, Balázs/0000-0003-3237-9222; Janáky, Csaba/0000-0001-5965-5173} } @mastersthesis{MTMT:34159130, title = {Ahol a fotoelektrokémia és az anyagtudomány találkoznak: egyszerű és összetett fotoelektródok előállítása és tulajdonságai}, url = {https://m2.mtmt.hu/api/publication/34159130}, author = {Janáky, Csaba}, unique-id = {34159130}, year = {2023}, orcid-numbers = {Janáky, Csaba/0000-0001-5965-5173} }
