New horizon in C1 chemistry: breaking the selectivity limitation in transformation of syngas and hydrogenation of CO₂ into hydrocarbon chemicals and fuels

Abstract

Recent advances in bifunctional catalysis for conversion of syngas and hydrogenation of CO2 into chemicals and fuels have been highlighted.

Single-pass transformation of syngas into ethanol with high selectivity by triple tandem catalysis

“…The incorporation of ZnO into ZrO 2 to form solid solution enhanced the signal at g value of 2.003 and thus the generation of oxygen vacancies over both ZnO-ZrO 2 and K + -ZnO-ZrO 2 samples. We believe that the increased density of oxygen vacancy sites favours the activation of CO as well as H 2 30,45,47 .…”

“…The compatibility of the catalyst with syngas stream, which contains both CO and H 2 , is also important for the carbonylation and hydrogenation reactions. For the normal carbonylation reaction, the catalyst works under CO atmosphere without H 2 21,36,[41][42][43] . Our studies reveal that the presence of H 2 did not significantly change the performance of H-MOR-DA-12MR in the carbonylation of methanol (Supplementary Table 11).…”

“…S yngas (H 2 /CO), which can be produced from natural (shale) gas, coal, biomass, carbon-containing waste and carbon dioxide, is one of the most important platforms for utilization of non-petroleum resources to supply energy and chemical feedstocks. The depletion of crude oil and the growing demand for fuels and chemicals have stimulated recent research activities in syngas transformations [1][2][3] . As an ideal fuel additive, a promising hydrogen carrier and a versatile building-block for chemicals, fuels and polymers 4,5 , ethanol is one of the most attractive molecules that may be produced from syngas.…”

Ethanol as a Binder to Fabricate a Highly‐Efficient Capsule‐Structured CuO−ZnO−Al2O3@HZSM‐5 Catalyst for Direct Production of Dimethyl Ether from Syngas

“…It has become a consensus to seek clean energy to replace fossil fuel because the latter is liable to pollute the environment . Dimethyl ether (DME) is expected to replace liquefied petroleum gas (LPG) for its alike physicochemical nature.…”

“…It has become a consensus to seek clean energy to replace fossil fuel because the latter is liable to pollute the environment. [1] Dimethyl ether (DME) is expected to replace liquefied petroleum gas (LPG) for its alike physicochemical nature. In addition, DME can also be employed as an eco-friendly replacement for diesel because of its high cetane number and low emission of toxic compounds in the outlet gas.…”
