Suitability of Cu-substituted beta-Mn2V2O7 and Mn-substituted beta-Cu2V2O7 for photocatalytic water-splitting

Raffaella Buonsanti, Michal Stanislaw Strach

The pyrovanadates beta -Mn2V2O7 and beta -Cu2V2O7 were previously investigated as photoanode materials for water splitting. Neither of them, however, was found to be sufficiently active. In this work, we predict the properties of these two structurally sim ...

Polymer Lamellae as Reaction Intermediates in the Formation of Copper Nanospheres as Evidenced by In Situ X-ray Studies

Chethana Janardhana Gadiyar, Kilian Frank, Raffaella Buonsanti, Valeria Mantella, Michal Stanislaw Strach, James Richard Pankhurst, Dragos-Constantin Stoian

The classical nucleation theory (CNT) is the most common theoretical framework used to explain particle formation. However, nucleation is a complex process with reaction pathways which are often not covered by the CNT. Herein, we study the formation mechan ...

Synthesis of Cu/CeO2-x Nanocrystalline Heterodimers with Interfacial Active Sites To Promote CO2 Electroreduction

Mounir Driss Mensi, Emad Oveisi, Chethana Janardhana Gadiyar, Raffaella Buonsanti, Seyedehbehnaz Varandili, Jianfeng Huang, Michal Stanislaw Strach, Gian Luca De Gregorio, Jan Vávra

Synergistic effects at metal/metal oxide interfaces often give rise to highly active and selective catalytic motifs. So far, such interactions have been rarely explored to enhance the selectivity in the electrochemical CO2 reduction reaction (CO2RR). Herei ...

Universal Oxide Shell Growth Enables in Situ Structural Studies of Perovskite Nanocrystals during the Anion Exchange Reaction

Seryio Saris, Raffaella Buonsanti, Anna Loiudice, Michal Stanislaw Strach

The ability to tune thin oxide coatings by wet-chemistry is desirable for many applications, yet it remains a key synthetic challenge. In this work, we introduce a general colloidal atomic layer deposition (c-ALD) synthesis to grow an alumina shell with tu ...

Assembly of -Cu2V2O7/WO3 heterostructured nanocomposites and the impact of their composition on structure and photoelectrochemical properties

Mariateresa Scarongella, Chethana Janardhana Gadiyar, Raffaella Buonsanti, Anna Loiudice, Michal Stanislaw Strach, Luca Rimoldi

Multinary metal oxides and their heterostructures play a key role as light absorbers in the production of solar chemicals. Synthetic tunability is crucial to understand the impact of composition and structure on the photoelectrochemical performance. Here, ...

Sizable Excitonic Effects Undermining the Photocatalytic Efficiency of beta-Cu2V2O7

Alfredo Pasquarello, Mariateresa Scarongella, Raffaella Buonsanti, Julia Anna Wiktor, Igor Reshetnyak, Michal Stanislaw Strach

Copper vanadates have been proposed as promising photoanodes for water-splitting photoelectrochemical cells, but their performance has recently been shown to be severely limited. To understand this behavior, we study the electronic structure and the optica ...
