20.500.12556/DKUM-84658 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. baker nanodelci elektrokataliza copper nanoparticles electrocatalytic hydrogeneration baker nanodelci elektrokataliza true false true Wiley Angleški jezik Slovenski jezik https://onlinelibrary.wiley.com/journal/21944296 Članek v reviji 2023-07-05 06:12:13 2024-04-19 08:39:10 2024-04-20 03:28:30 0000-00-00 00:00:00 2023 0 0 str. 1-9 ǂiss. ǂ6, [article no.] 2201467 ǂVol. ǂ11 Jun. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-12-16 0000-00-00 2023-03-12 620.3 147314947 10.1002/ente.202201467 2194-4296 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 DC2BBE95F8BD5B70B2434D43FFB23BE5 aa7f0c46de8d8979d6e0a57fb8aee99bb626cdcef633f88ff5db502b7283b11d 5d7646bc-fe18-11ee-8dad-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=178735 https://onlinelibrary.wiley.com/doi/10.1002/ente.202201467 0 667225d0-fe18-11ee-8dad-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=178736 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
