20.500.12556/RUL-167087 Insights into electrocatalytic hydrogenation of furfural on nanoparticulate Pd/C under acidic conditions In this work, we present an insight into the mechanism of electrochemical hydrogenation of furfural on carbon supported palladium nanoparticles. By directly coupling electrochemistry with mass spectrometry, we were able to, for the first time, deconvolute the hydrogen evolution reaction and electrochemical hydrogenation by measuring the mass signal for hydrogen and 2-methylfuran. This approach also allowed us to extract the Tafel slopes for each reaction and get insights into mechanisms. The results indicate that the hydrogenation occurs by a Langmuir–Hinshelwood type process rather than by proton-coupled electron transfer. Further findings recognize the blocking character of furfuryl alcohol (FA) where the latter or one of its intermediates blocks the electrochemical hydrogenation. Additionally, FA is shown to be a precursor for 2-methyl furan formation. Accordingly, specific guidelines towards improvement of reaction performance are suggested. electrocatalysis electrochemical hydrogenation electrochemistry–mass spectrometry furfural elektrokemija paladij ogljik vodik hidrogeniranje true false true Angleški jezik Slovenski jezik Članek v reviji 2025-02-07 09:50:44 2025-02-07 09:50:44 2025-12-03 16:34:48 0000-00-00 00:00:00 2025 0 0 9 str. iss. 3, art. e202401474 Vol. 17 Feb. 6, 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 544.5/.6 1867-3899 10.1002/cctc.202401474 216646147 ChemCatChem_-_2024_-_Maselj_-_Insights_Into_Electrocatalytic_Hydrogenation_of_Furfural_on_Nanoparticulate_Pd_C_Under_Acidic.pdf ChemCatChem_-_2024_-_Maselj_-_Insights_Into_Electrocatalytic_Hydrogenation_of_Furfural_on_Nanoparticulate_Pd_C_Under_Acidic.pdf 1 2F9D94C59C38A613C736D661969B5DA7 9c681e58cb12e5f1b05ad05c39e653a7199aecdc7b200488925e5221f15eee81 f6d1d2b4-ed07-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199701 https://chemistry-europe.onlinelibrary.wiley.com/doi/10.1002/cctc.202401474 0 0b792200-e530-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199254 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
