Controlled assembly of nitrogen-doped iron carbide nanoparticles on reduced graphene oxide for electrochemical reduction of carbon dioxide to syngas

Ab Initio Thermodynamic Stability of Carbide Catalysts under Electrochemical Conditions

“…Moreover, quantitatively confirming the intuitive correlation of the electrochemical stability window with the Ocarbide interaction strength suggests extending future investigations to later TMCs, where oxide formation could then be less problematic. Indeed, there has been a recent report of CO2RR activity at iron carbide catalysts, 42 while a cobalt carbide catalyst showed high selectivity in the related thermal CO 2 hydrogenation. 43 With Mn falling in between Cr and Fe in the periodic table, manganese carbides appear particularly interesting from this perspective.…”

Sn-based electrocatalysts for electrochemical CO2 reduction

“…129 Albeit carbon-based materials are electrocatalytically inert for CO 2 RR, these materials, however, featured with high surface area and conductivity, can be employed as support for our catalysts because in this way, nanocatalysts can be better dispersed and aggregation reduced, and charge transport can also be enhanced. 130 Inspired by this, Li et al hydrothermally grew SnS 2 nanosheets on reduced graphene oxide (SnS 2 /rGO) to catalyze the CO 2 RR, affording amazing performance metrics (13.9 mA cm À2 , 84.5%), as shown in Fig. 6b.…”

Magnetic Technologies and Green Solvents in Extraction and Separation of Bioactive Molecules Together with Biochemical Objects: Current Opportunities and Challenges

“…Organic small molecules are sometimes used in the modification process to obtain Fe 3 O 4 magnetic nanoparticles with good properties. Currently, oleic acid (OA) or oleylamine have been considered to modify MNPs through solvothermal [70] or pyrolysis method [71]. These two compounds all have a C 18 long alkyl chain, and this is good to maintain the stability of the magnetic fluid.…”
