Effect of preparation methods of ZnO/ZrO2 catalysts for methanol synthesis from CO2 hydrogenation

Atomic/molecular layer deposition strategies for enhanced CO2 capture, utilisation and storage materials

“…442 Cobalt carbide (Co 2 C) has also shown promise due to its effective capabilities in activating CQO and coupling C-C. 443 The Cu/ZnO/Al 2 O 3 catalyst, extensively researched and employed in the industrial syngas to methanol process for many years, demonstrated remarkable performance in methanol production from syngas. 444 However, it has limited its effectiveness in CO 2 hydrogenation to methanol, promoting research into its modification. More recently, catalysts incorporating different components, such as ZnO-ZrO 2 , MoS 2 , and Cu/ M@SiO 2 (where M can be Ti, Zr, Nb, or Ta), have emerged as potential superior catalysts for this particular reaction.…”

Solar thermochemical CO 2 splitting is another promising approach for converting CO 2 into carbon monoxide and oxygen using solar energy as the driving force.…”

“…479 Loading these active sites through the ALD technique into different supports has attracted much attention in this reaction. 444,480 High dispersion of active sites with an appropriate interface with the support can provide more oxygen vacancies on the surface to increase CO 2 activation, resulting in increased catalytic activity for methanol production. Liu and colleagues 457 explored the catalytic performance of partially reduced ZnO 1Àx /Cu interfaces within Zn/Cu(OH) 2 for methanol production from CO 2 .…”
