Supercritical Antisolvent Process to Produce Cerium Oxide Nanoparticles as a Support for High-Activity Platinum Catalysts

open access: yesChemical Engineering Transactions, 2017
Cerium acetylacetonate (Ce(acac)3) was precipitated from methanol (MeOH) using supercritical antisolvent process (SAS). The precursor was, then, calcined obtaining the cerium oxide (CeO2).

Simultaneous Photoactivation of Copper and Ti‐Doped CeO2−x Enables Optimal Acceleration of the RWGS Reaction

open access: yesCarbon Energy, EarlyView.
A combination of visible light and thermal energy accelerates the CO formation rate up to 57 times compared to dark conditions using a 3Cu/CeTiO2−x catalyst. Kinetic analysis, as well as steady state and transient spectroscopy, was applied under photocatalytic conditions to analyze and disentangle the reaction channels under dark and illuminated ...

Beyond Activity: The Unified Framework of the Sabatier Principle to Guide Rational Design of Durable and Active Electrocatalysts

open access: yesCarbon Energy, EarlyView.
In this review, a unified framework of the Sabatier principle is applied to a diverse range of catalytic and electrocatalytic systems for advanced clean energy technologies, with a particular focus on the oxygen reduction reaction (ORR). This approach will guide the design and development of highly active and stable catalysts for fuel cells ...

Oxygenophilic Cerium Promotes Active Species Generation and Modulates the Interfacial Water Network in Electrocatalytic Water Oxidation

open access: yesCarbon Energy, EarlyView.
CeO2 dendrites are introduced to modify the NiSx/C3N4 nanorods, constructing hexagonal star‐like forest arrays (CeO2@NiSx/C3N4). The oxophilicity of Ce species generates abundant oxygen vacancies, which subsequently facilitate the in situ evolution of active amorphous NiOOH.
