Contact dynamics for a solid-solid reaction mediated by gas-phase oxygen: Study on the soot oxidation over ceria-based catalysts

Ceria-based catalysts with different topological and textural properties have been prepared to study the role of the soot-catalyst contact on the soot oxidation reaction. The physico-chemical features of the catalysts have been investigated by means of complementary techniques, such as powder XRD, N₂ physisorption at -196 °C,...

Syngas Production from Electrochemical Reduction of CO2: Current Status and Prospective Implementation

The CO2 that comes from the use of fossil fuels accounts for about 65% of the global greenhouse gases emissions, and it plays a critical role in global climate changes. Among the different strategies that have been considered to address the storage and reutilization of CO2, the transformation of CO2 into chemicals or fuels with a high added...

Syngas production by electrocatalytic reduction of CO ₂ using Ag-decorated TiO ₂ nanotubes

Huge efforts have been done in the last years on electrochemical and photoelectrochemical reduction of CO ₂ to offer a sustainable route to recycle CO ₂ . A promising route is to electrochemically reduce CO ₂ into CO which, by combination with hydrogen, can be used as a feedstock to different added-value...
