Enhanced Bulk Transport in Copper Vanadate Photoanodes Identified by Combinatorial Alloying

From Stochastic Self‐Assembly of Nanoparticles to Nanostructured (Photo)Electrocatalysts for Renewable Power‐to‐X Applications via Scalable Flame Synthesis

“…Thereafter, the best performing candidates will be synthesized, characterized, and validated experimentally. [20][21][22][23] This approach may save time and resources at the trial-and-error stage, where combinations of elements in the periodic table create hundreds of thousand compounds that cannot be easily synthesized and tested within a short time frame. Nevertheless, the capital investment to build (super)computers, the accuracy of the theories/models or the complexity of the actual systems, and the ability to connect other bodies of knowledge of all related fields to work harmoniously are challenging.…”

Assessing the Suitability of Copper Vanadate (Cu11V6O26) for Use as a Photoanode Material for Photoelectrochemical Water Oxidation

“…Ternary metal oxides have been widely applied as photoelectrodes for solar water splitting because of their relatively small band gap (1.8–2.1 eV) and good photostability in aqueous solutions. ,− Among them, copper vanadate photoelectrodes (α-CuV 2 O 6 , β-Cu 2 V 2 O 7 , γ-Cu 3 V 2 O 8 , Cu 5 V 2 O 10 , etc.) have attracted much attention for photoelectrochemical water splitting. − In our previous work, we prepared β-Cu 2 V 2 O 7 and Cu 5 V 2 O 10 thin films using the spray pyrolysis method and demonstrated these mixed metal oxides as two promising photoelectrode candidates. , Jiang et al reported a γ-Cu 3 V 2 O 8 film with suitable band structure and excellent PEC stability and applied it as a photoanode for water electrolysis . Cu 11 V 6 O 26 is another promising photoanode material for the water splitting reaction.…”

A Faster Path to Solar Water Splitting

“…The color of the points indicates the alloy loading, ranging from 0% (black) to 8% (yellow). Alloying increases P max , but reduces the optical absorption at low photon energies (reproduced with permission from Newhouse et al [4]).…”

“…In the second paper, the JCAP team switched from high throughput photoanode discovery to high throughput modification of a single photoanode material, -Cu 2 V 2 O 7 [4]. Cu 2 V 2 O 7 shows good visible light absorption starting at photon energies of 2 eV, but this does not result in good photoactivity at lower energies due to the formation of excitons [5].…”
