CO2-mediated hydrogen storage and release cycles realized by a bimetallic ruthenium complex in pure water

Jiaqi Xu

CO2-mediated liquid H2 storage is a promising technology; however, it typically requires additives such as bases, which increase both cost and energy consumption. Herein, a bimetallic Ru complex is fabricated that catalyzes reversible cycles of CO2 hydroge ...

TaOx electron transport layers for CO2 reduction Si photocathodes

Raphaël François Lemerle, Elif Nur Dayi

Electron transport layers (ETLs) used as components of photocathodes for light-driven CO2 reduction (CO2R) in aqueous media should have good electronic transport, be stable under CO2R conditions, and, ideally, be catalytically inert for the competing hydro ...
