Recent advances in direct catalytic hydrogenation of carbon dioxide to valuable C₂₊ hydrocarbons

Abstract

Research progress on directly converting CO2 into heavy hydrocarbons via heterogeneous catalysis is summarized and discussed.

Novel Heterogeneous Catalysts for CO2 Hydrogenation to Liquid Fuels

“… 12 However, direct reduction of CO 2 to C 2+ products is still a grand challenge due to the lack of efficient catalysts with high stability, as the activity of C–C coupling is low and the formation of byproduct water can easily deactivate the various catalysts for CO 2 conversion. 2 , 13 − 15 Syngas (CO/H 2 ) and CH 3 OH are the most important C1 platform molecules, and their conversions to value-added products via the Fischer–Tropsch synthesis (FTS) and methanol to hydrocarbons (MTH) processes, respectively, were extensively applied in industry. 16 − 19 Therefore, combining the reverse water–gas shift (RWGS) with FTS and combining high-temperature methanol synthesis with MTH over bifunctional/multifunctional catalysts are two efficient strategies for direct CO 2 hydrogenation to C 2+ hydrocarbons including liquid hydrocarbons.…”

A Critical Look at Direct Catalytic Hydrogenation of Carbon Dioxide to Olefins

“…[29,30] There are several recenta nd good reviewso nC O 2 hydrogenation. [31][32][33][34][35][36][37][38][39] These typically focus on the production of hydrocarbons, rather than on olefins. Interesti nC O 2 hydrogenation to olefins hasb een increasing, and severalr eviewsh ave focused on this topic.…”

Beyond Cars: Fischer‐Tropsch Synthesis for Non‐Automotive Applications

“…Exceptional F‐T performance is observed as compared to conventional F‐T synthesis. Alternatively, in terms of changing reaction feedstocks based on F‐T synthesis, one can employ CO 2 and H 2 instead of CO and H 2 as feedstocks, which is called as CO 2 ‐F‐T process to produce liquid fuels and chemicals ,. Beyond that, new highly active and stable F‐T catalysts can be synthesized by metal organic frameworks (MOFs) as precursors .…”
