Insights into the Performance of CoxNi1-xTiO3 Solid Solutions as Photocatalysts for Sun-Driven Water Oxidation

CoNiTiO systems evaluated as photo- and electrocatalytic materials for oxygen evolution reaction (OER) from water have been studied. These materials have shown promising properties for this half-reaction both under (unbiased) visible-light photocatalytic approach in the presence of an electron scave...

description CoNiTiO systems evaluated as photo- and electrocatalytic materials for oxygen evolution reaction (OER) from water have been studied. These materials have shown promising properties for this half-reaction both under (unbiased) visible-light photocatalytic approach in the presence of an electron scavenger and as electrocatalysts in dark conditions in basic media. In both situations, CoNiTiO exhibits the best performance and is proved to display high faradaic efficiency.
