نویسندگان

چکیده

Formic acid production from CO2 allows the reduction of carbon dioxide emissions while synthesizing a product with wide range applications. hydrogenation is challenging due to cost transition metal catalysts and toxicity elements. In this work, thermodynamic confinement effects metal–organic framework UiO-66 on formic were studied by force field-based molecular simulations. The frameworks Cu-BTC, IRMOF-1 compared, assess impact different pore size centers HCOOH. Monte Carlo simulations in grand-canonical ensemble performed frameworks, using gas phase mole fractions CO2, H2, HCOOH at chemical equilibrium, obtained Continuous Fractional Component Reaction Ensemble. adsorption isobars components computed 298.15 – 800 K, 1 60 bar. enhancement preferential was calculated for all conditions. UiO-66, affect reaction, shifting thermodynamical equilibrium toward formation. prevailing factor type center framework. effect Cu-BTC turns out exceed caused IRMOF-1. resulting fraction increased ca. 2000 times compared can be considered as an alternative improve elimination high-cost temperature elevation, downstream processing methods, comparable final concentration reported concentrations formate catalysts.

Direct synthesis of formic acid from carbon dioxide by hydrogenation in acidic media

The chemical transformation of carbon dioxide into useful products becomes increasingly important as CO2 levels in the atmosphere continue to rise as a consequence of human activities. In this article we describe the direct hydrogenation of CO2 into formic acid using a homogeneous ruthenium catalyst, in aqueous solution and in dimethyl sulphoxide (DMSO), without any additives. In water, at 40 °...
