Indium oxide is an emerging photocatalyst for effective CO2 transformation which has been investigated extensively in our group. However, its drawbacks including limited light absorbance and high price impede the practical implementations. In this paper, Truong and co-authors demonstrate a new strategy to overcome both dilemmas by coating a nanoscale-thin indium oxide layer on a cheap, broadband-absorbance, plasmonic titanium nitride microstructure.
