Dolomite-supported Cu2O as heterogeneous photocatalysts for solar fuels production

Solar-driven CO2 reduction using modified earth-abundant ilmenite catalysts

“…The dolomite reacted with acetic acid (5% v/v) to generate a pure flow of CO 2 that was conducted to photocatalytic reactor at the same volumetric flow than the first scenario. The properties of the dolomite used was previously reported [ 3 ]. In this case, CO 2 was generated from the dolomite (as ii), but in this scenaroi the reactor was exposed to direct solar irradiation.…”

“…However, to scale up this process, it is necessary to obtain the photocatalysts directly from nature (e.g., minerals) without using complicated, toxic, and expensive reactants [ 1 ]. So far, there are a limited number of reports about using minerals directly as a photocatalyst or as support for CO2RR [ [2] , [3] , [4] , [5] , [6] , [7] , [8] ]. In these works, the use of earth-abundant materials has promoted better efficiencies than bare semiconductors for CO 2 reduction to generate various solar fuels such as HCOOH, HCOH, CH 3 OH, CO, and CH 4 , as is shown in Table 1 .…”

Cu/ZnV2O4 Heterojunction Interface Promoted Methanol and Ethanol Generation from CO2 and H2O under UV–Vis Light Irradiation

“… 18 Supported Cu 2 O promoted photoinduction efficiency under visible light. 19 − 22 Cu-modified TiO 2 exhibited light olefin selectivity of 60.4% at 150 °C, attributed to the Cu + species for C–C coupling. 23 Another study found that there exists a synergistic effect between Cu 1+ and Cu 2+ .…”

“…The Cu 2 O (110) crystal plane enabled CO 2 to be converted to • CO 2 , which increases the photoreduction efficiency, whereas the Cu 2 O (100) plane was inert . Supported Cu 2 O promoted photoinduction efficiency under visible light. − Cu-modified TiO 2 exhibited light olefin selectivity of 60.4% at 150 °C, attributed to the Cu + species for C–C coupling . Another study found that there exists a synergistic effect between Cu 1+ and Cu 2+ .…”
