20.500.12556/RUL-147353 Time and potential-resolved comparison of copper disc and copper nanoparticles for electrocatalytic hydrogenation of furfural Herein, a comparative analysis of two case example catalysts for electrocatalytic hydrogenation (ECH) of furfural under acidic conditions, namely a copper polycrystalline disc and copper nanoparticles dispersed on carbon support, is performed. To gain a detailed insight on ECH trends, a task-specific methodology is employed based on electrochemistry–mass spectrometry coupling, which enabled time- and potential-resolved detection of volatile ECH products, i.e., 2-methylfurane (2-MF) and H2. In this way, the ability to elucidate potential-dependent product distribution for the two catalysts, namely faradaic efficiency, is achieved. Accordingly, the nanoparticulate analog is significantly more active toward competitive hydrogen evolution reaction and 2-MF production, whereas the polycrystalline sample is more selective toward furfuryl alcohol. The observed differences in ECH are ascribed to alterations in surface domains, which is supported by surface-sensitive lead underpotential deposition characterization. copper nanoparticles electrocatalytic hydrogenation electrochemistry–mass spectrometry furfural baker nanodelci elektrokataliza true false true Angleški jezik Slovenski jezik Članek v reviji 2023-07-03 10:45:01 2023-07-03 10:45:02 2023-07-04 03:34:57 0000-00-00 00:00:00 2023 0 0 9 str. iss. 6, art. 2201467 Vol. 11 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.3 2194-4296 10.1002/ente.202201467 147314947 Energy_Tech_-_2023_-_Maselj_-_Time_and_Potential‐Resolved_Comparison_of_Copper_Disc_and_Copper_Nanoparticles_for.pdf Energy_Tech_-_2023_-_Maselj_-_Time_and_Potential‐Resolved_Comparison_of_Copper_Disc_and_Copper_Nanoparticles_for.pdf 1 DC99FC5E9E35B670FD69B039B630BAA1 2cab1e9287dc65d3f44497b0b8372bd214870ea1c84a22aba2b9aa817c043aae ac16713c-197d-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=170891 https://onlinelibrary.wiley.com/doi/10.1002/ente.202201467 1 7d38ea72-197d-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=170890 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
