Nevertheless, the direct formation of C<jats:sub>3<\/jats:sub> products encounters significant limitations due to the C<jats:sub>2<\/jats:sub>\u2013C<jats:sub>1<\/jats:sub> coupling reaction, posing a considerable challenge to improving their faradaic efficiency. Here, a design for an elevated pressure cascade catalytic reactor to convert CO<jats:sub>2<\/jats:sub> to C<jats:sub>3<\/jats:sub> products in a two\u2010step electrochemical process is presented. At 25\u2009bar pressure, by regulating the potential of the cascade system and the electrolyte flow rate, a 40% selectivity for 2\u2010propanol on a copper electrode placed upstream of a silver electrode that converts CO<jats:sub>2<\/jats:sub> to CO is reported. In cascade mode (with both silver and copper electrodes active), the C<jats:sub>3<\/jats:sub>:C<jats:sub>2<\/jats:sub> oxygenate ratio significantly increases to 7 compared to the noncascade mode (copper only) with a modest ratio of about 0.6. Therefore, our elevated pressure cascade electrolysis approach demonstrates a notable step forward in CO<jats:sub>2<\/jats:sub> electroreduction to oxygenated C<jats:sub>3<\/jats:sub> products.<\/jats:p>","DOI":"10.1002\/cssc.202500695","type":"journal-article","created":{"date-parts":[[2025,5,25]],"date-time":"2025-05-25T22:08:33Z","timestamp":1748210913000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Cascade Electrocatalytic Conversion of CO<sub>2<\/sub> to C<sub>3<\/sub> Products at Elevated Pressures"],"prefix":"10.1002","volume":"18","author":[{"given":"Nandalal","family":"Girichandran","sequence":"first","affiliation":[{"name":"Process &amp; Energy Department, Faculty of Mechanical Engineering Delft University of Technology  Leeghwaterstraat 39 2628 CB Delft Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lakshmi","family":"Mohan","sequence":"additional","affiliation":[{"name":"Process &amp; Energy Department, Faculty of Mechanical Engineering Delft University of Technology  Leeghwaterstraat 39 2628 CB Delft Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanne","family":"Buisman","sequence":"additional","affiliation":[{"name":"Process &amp; Energy Department, Faculty of Mechanical Engineering Delft University of Technology  Leeghwaterstraat 39 2628 CB Delft Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Morrison","sequence":"additional","affiliation":[{"name":"Electrochemical Innovation Lab, Department of Chemical Engineering University College London  London WC1E 7JE UK"},{"name":"The Faraday Institution, Quad One, Harwell Science and Innovation Campus  Didcot OX11 0RA UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9412-7480","authenticated-orcid":false,"given":"Ruud","family":"Kortlever","sequence":"additional","affiliation":[{"name":"Process &amp; Energy Department, Faculty of Mechanical Engineering Delft University of Technology  Leeghwaterstraat 39 2628 CB Delft Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,6,10]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.aat8789"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.8b00705"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jpclett.5b01559"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41929-019-0235-5"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41929-019-0306-7"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cattod.2024.114805"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.99.016105"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1039\/c1cp20547a"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joule.2020.07.009"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsaem.9b00791"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1039\/D2MA00188H"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.electacta.2018.04.072"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.iecr.1c03592"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1039\/C8EE01501E"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.2c09956"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.energyfuels.3c05194"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1021\/acscatal.5b01967"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1612106114"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1039\/C4CP03340J"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.susc.2016.08.006"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature13249"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41929-023-00938-z"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cej.2024.150478"},{"key":"e_1_2_7_25_1","first-page":"1","volume":"1","author":"Morrison A.
