“…However, there is no clear trend in influence of the space velocity on selectivity. Sun et al [31] showed that the methanol selectivity decreases with lower space velocity. It can be explained by additional formation of CO from the secondary reaction of methanol decomposition (CH 3 OH = CO + 2H 2 ) under the chosen reaction conditions.…”

catalyst can operate in a stable way without the presence of carbon monoxide in the feed, which means that increased water contents in the product gas cannot destroy the catalyst's performance completely. The presence of benzene in the feed does not lead to a deactivation of the catalyst. With these findings methanol production starting from exhaust gases from steel mills seems to become an interesting alternative for sustainable methanol production.Abstract CO 2 hydrogenation as a route for the chemical energy storage over a commercial Cu/ZnO/Al 2 O 3 catalyst has been studied. To check the optimal conditions for an efficient methanol production the influence of temperature and space velocity on the catalytic performance has been demonstrated. Time-on-stream measurements in the absence and the presence of benzene in the gas feed mixture were performed to investigate the possibility to use alternative carbon sources, which contain traces of aromatics.

“…5.3), supporting the hypothesis that the reactivity of multicomponent catalysts no longer depends only on the availability of Cu sites [11, 25-30, 87, 89]. Particularly, a peculiar surface affinity to CO 2 , enhancing the formation of reactive intermediates, as a key factor of the reactivity of promoted Cu catalysts could be taken into account [28,29,36,[87][88][89][90].…”

“…5.4), supporting the thought that CO 2 -hydrogenation systems might bear a balanced exposure of metal (MSA) and oxide (OSA) surface [11]. This also explains the negative effect of an overwhelming MSA exposure on the reactivity of Cu-ZnO and Cu-ZnO/Al 2 O 3 catalysts [87].…”

“…Finally, experimental evidences concerning the reaction network leading to MOH and CO formation generally show a positive effect of the space velocity on methanol selectivity [28][29][30]87], resulting in steadily decreasing selectivity-conversion relationships [25][26][27]. Altogether these evidences indicate the occurrence of a consecutive reaction network leading to the primary formation of methanol (MS) at low temperature (e.g.…”

CO 2 hydrogenation is one of the most promising processes in response to energy crisis and greenhouse gas emission. There is, however, still a lack of a highly efficient and sustainable catalyst for this reaction. In this study, a novel low-cost coreshell structured CuIn@SiO 2 catalyst is prepared by a solvothermal method and used for catalyzing CO 2 hydrogenation to methanol. A significant interaction exists between Cu and In, promoting Cu dispersion and reducibility, Cu 2 In alloy and oxygen vacancy formation. Moreover, plenty of interfacial sites are formed between Cu 2 In and In 2 O 3 , which further enhances CO 2 adsorption and activation. CuIn@SiO 2 , therefore, shows not only a satisfactory catalytic stability due to core-shell formation but also an excellent catalytic performance. 9.8% CO 2 conversion, 78.1% CH 3 OH selectivity, and 13.7 mmol CH 3 OH Áh −1 Ág cat −1 CH 3 OH space-time yield are obtained at the space velocity of 20,000 mLÁg cat −1 Áh −1 . CuIn@SiO 2 possesses a great potential as catalyst for CO 2 hydrogenation in a moderate condition in industry.
