Tandem Catalysis for CO2 Hydrogenation to C2–C4 Hydrocarbons

Abstract: Conversion of carbon dioxide to C-C hydrocarbons is a major pursuit in clean energy research. Despite tremendous efforts, the lack of well-defined catalysts in which the spatial arrangement of interfaces is precisely controlled hinders the development of more efficient catalysts and in-depth understanding of reaction mechanisms. Herein, we utilized the strategy of tandem catalysis to develop a well-defined nanostructured catalyst CeO-Pt@mSiO-Co for converting CO to C-C hydrocarbons using two metal-oxide interf… Show more

“…Remarkably,t he selectivity of ethylene alone (excluding CO 2 )r eaches as high as 83 %, which is much higher than the 23 %o btained over ZnCrO x -MSAPO (see Figure S2). [3a] Such an ethylene selectivity is unprecedented in any other direct syngas conversion process [2,12] and also higher than that of the MTO processes reported so far. [1,13] Furthermore,t he selectivity of the byproduct CH 4 is only 5%.F igure 1B shows that CO conversion increases with the temperature and reaches 11 % at 390 8 8Cw hile C 2 = selectivity still remains at 71 %.…”

“…[1] In comparison, direct conversion of syngas into ethylene is attractive because it involves fewer operation units.This transformation has been under extensive study for over 50 years with efforts mainly focusing on modification of Fe-a nd Co-based FTS catalysts. [2] Despite significant pro-gress, [2c,e, 3] the C 2 = selectivity remains low and the highest C 2 selectivity (including C 2 = and ethane C 2 8 8)i sp redicted to be 30 %b yt he Anderson-Schultz-Flory (ASF) model in the conventional FTS (see Figure S1 in the Supporting Information).Previous studiesd emonstratedt hataselectivity of ethane as high as 83 %c an be obtained by applying ZSM-5 impregnatedw ithC r, Zn,a nd Al,b ut no ethylene,w hich is obviouslyamuch more valuable C 2 product, wasdetected.

“…Although much progress has been made, the IL-mediated CO 2 hydrogenation to hydrocarbons has rarely been reported in the literature. Various ILs and solvents were examined in the hydrogenation of CO 2 catalyzed by Pd(PtBu 3 ) 2 and FeCl 2 in the presence of Xantphos, and the resultsa re listed in Ta ble 1a nd Table S1 in the Supporting Information. In this protocol, the combination of 1-butyl-3methylimidazolium hexafluorophosphate ( CO 2 = 2:1) at 9MPa, ay ield of 1.08 C-mmol was achieved, together with as electivity towards C 2 -C 4 hydrocarbons up to 98.3 C-mol %, much highert han those obtainedo ver the catalysts reported in the literature.…”

[2] The selective hydrogenation of CO 2 to C 2 -C 4 hydrocarbons is ap romising path, but it imposes major technological challenges owing to the thermodynamic stabilitya nd kinetic inertness of CO 2 and suffers from low selectivity towards to C 2 -C 4 hydrocarbons.
