“…In order to improve the performance of Fe catalysts in CO 2 hydrogenation, the effects of promoter [8,10,13,15,19–24], supporter [15,20,22,24,25], preparation method [8,13,15,21–26] and reducing agent [8] are studied very much. In these studies, iron oxide almost presents in α-Fe 2 O 3 [15,21,26] or Fe 3 O 4 [25] crystal phase in the as-prepared catalysts.…”

“…In these studies, iron oxide almost presents in α-Fe 2 O 3 [15,21,26] or Fe 3 O 4 [25] crystal phase in the as-prepared catalysts. Considering that γ-Fe 2 O 3 is one kind of iron oxide as common as α-Fe 2 O 3 [27,28], it is surprising that there are very few reports about the behavior of γ-Fe 2 O 3 in CO 2 hydrogenation.…”

The effect of Fe2O3 crystal phases on CO2 hydrogenation

The effect of Fe2O3 crystal phases on their performance in CO2 hydrogenation was studied. α-Fe2O3 crystal was prepared by precipitation method from Fe(NO3)3·9H2O and (NH4)2CO3, and γ-Fe2O3 was prepared by grinding Fe(NO3)3·9H2O and L(+)-Tartaric acid in agate mortar completely. The crystal phases of Fe2O3 influence the distribution of promoter Zn, K and Cu on catalysts. The dispersity of K on γ-Fe2O3 surface is higher than α-Fe2O3. On the contrary, Cu and Zn are more dispersive on α-Fe2O3 surface than γ-Fe2O3. The catalyst in γ-Fe2O3 phase is easily reduced relative to the catalyst in α-Fe2O3 phase. The former presents higher CO2 conversion and C2+ hydrocarbon selectivity than the latter in CO2 hydrogenation.

“…Out of the three CO 2 conversion processes mentioned, CO 2 hydrogenation to long-chain hydrocarbons is the least studied and characterized process. Recently a nanostructured Fe 2 O 3 material prepared by template-assisted synthesis shows improved conversion and selectivity [96] but we are at the early beginnings of the industrial development of these reactions.…”

It is not the first time in human history, nor will it be the last for that matter, that a collective problem calls for a collective response. Climate change fueled by greenhouse emissions affects humankind alike. Despite the disagreement among policymakers and scientists on the severity of the issue, the truth is that the problem remains. A broad look at different technologies being used today in different fields has led to the idea of bringing them together in an attempt to offer a viable solution to reducing anthropogenic CO 2 . The following paper describes how the nanotechnologies, available or soon to be available, would make CO 2 capture, cache, and conversion (coined the three Cs) a valid way for achieving a more sustainable energy society. Authors also set out to highlight with this work how knowledge transfer is instrumental in the development of technology and how methodical assessment of crossovers can expedite research when time plays against us.
