Metal and nitrogen codoped carbons (M-N/Cs) have emerged as promising alternatives to platinum-based catalysts for the oxygen reduction reaction (ORR). DFT calculations are used to investigate the adsorption of anions and impurities from the electrolyte on the active site, modeled as an M-N-4 motif embedded in a planar carbon sheet (M=Cr, Mn, Fe, Co). The two-dimensional catalyst structure implies that each metal atom has two potential active sites, one on each side of the sheet.]]>Fri, 06 Dec 2019 08:00:00 +0200https://v-sustain.dtu.dk/news/nyhed?id=a8e764c1-f8c7-49b0-9325-d24fdeb38aabhttps://v-sustain.dtu.dk/news/nyhed?id=f37ebbf9-1742-44f5-9be0-f615038adad1
Unlike energy efficiency and selectivity challenges, the kinetic effects of impure or intentionally mixed CO2 feeds on the catalytic reactivity of the direct electrochemical CO2 reduction reaction (CO2RR) have been poorly studied. Given that industrial CO2 feeds are often contaminated with CO, a closer investigation of the CO2RR under CO2/CO co-feed conditions is warranted.]]>Wed, 27 Nov 2019 15:29:22 +0200https://v-sustain.dtu.dk/news/nyhed?id=f37ebbf9-1742-44f5-9be0-f615038adad1https://v-sustain.dtu.dk/news/nyhed?id=d2f16b88-5d5b-41ee-9f5d-ed83df9371f9
Cell designs that integrate membrane-electrode assemblies (MEAs) with highly selective catalysts are a promising route to reduce ohmic losses and achieve high energy efficiency in CO2 reduction at industrially relevant current densities. In this work, porous silver filtration membranes are demonstrated as simple and efficient gas-diffusion electrodes for CO2 reduction to CO at high current densities in an MEA-type device. A partial current density for CO of up to ca. 200 mA cm(-2) was achieved at a cell voltage of ca. 3.3 V, in tandem with minimal H-2 production.]]>Wed, 06 Nov 2019 08:00:00 +0200https://v-sustain.dtu.dk/news/nyhed?id=d2f16b88-5d5b-41ee-9f5d-ed83df9371f9https://v-sustain.dtu.dk/news/nyhed?id=ac3f7409-2c40-4ae4-88a8-14c5505d0aee
Sustainable ammonia synthesis: SUNCAT’s lithium-cycling strategy. Research suggests new direction for ammonia synthesis]]>Fri, 18 Aug 2017 12:32:18 +0200https://v-sustain.dtu.dk/news/nyhed?id=ac3f7409-2c40-4ae4-88a8-14c5505d0aeehttps://v-sustain.dtu.dk/news/nyhed?id=662a9964-a892-4860-8c65-0b335d6e386c
The N2 molecule is particularly inert; the N−N triple bond is one of the most stable in all of chemistry, and in addition, the molecule has no dipole moment and a very low polarizability. Therefore, one of the major challenges in chemistry today is to find new ways to activate N2.]]>Mon, 14 Aug 2017 14:25:21 +0200https://v-sustain.dtu.dk/news/nyhed?id=662a9964-a892-4860-8c65-0b335d6e386chttps://v-sustain.dtu.dk/news/nyhed?id=076261c8-3c6f-4633-a731-67dbab66a50c

Renewable energy is providing an increasing share of the energy supply, but to ensure the green transition continues, it must also be able to furnish us with the fuels and chemicals that combined account for 25 per cent of the world's energy consumption. Electrocatalysis is a technology that can do just that, but is facing major challenges, as shown in a recent article in the Science journal.]]>Thu, 19 Jan 2017 11:43:02 +0200https://v-sustain.dtu.dk/news/nyhed?id=0940fadf-df3f-46f5-98fd-98f11467be58https://v-sustain.dtu.dk/news/nyhed?id=e5845962-a973-4bdf-9c2a-3dc86a8e8c84
Summary A quarter of humanity's current energy consumption is used for transportation (1). Low-temperature hydrogen fuel cells offer much promise for replacing this colossal use of fossil fuels with renewables; these fuel cells produce negligible emissions and have a mileage and filling time equal to a regular gasoline car. ]]>Thu, 15 Dec 2016 15:10:00 +0200https://v-sustain.dtu.dk/news/nyhed?id=e5845962-a973-4bdf-9c2a-3dc86a8e8c84https://v-sustain.dtu.dk/news/nyhed?id=aae3802b-6560-4ce9-89d7-bc2042a7f5a4

A detailed understanding of the electrochemical reduction of CO2 into liquid fuels on rutile metal oxide surfaces is developed by using DFT calculations. We consider oxide overlayer structures on RuO2 (1 1 0) surfaces as model catalysts to elucidate the trends and limitations in the CO2 reduction reaction (CO2RR) based on thermodynamic analysis. ]]>Wed, 26 Oct 2016 08:00:00 +0200https://v-sustain.dtu.dk/news/nyhed?id=972ed69c-ec58-4a46-b46c-d6091e1976c6https://v-sustain.dtu.dk/news/nyhed?id=de183571-a261-42ee-8c63-7763cd20edc6
