We used this enhanced absorption as a tool to optically detect ammonia at near-to-room temperatures (100 C) which is unusual for oxide-based sensors.
This is so exciting because it opens up new possibilities in optical sensing of hazardous gases!

Here we used TiO2 and Au nanocrystals and assembled them into coatings of precise thickness and surface coverage, obtaining structures that when deposited on a mirror, were able to absorb broadly in the visible an near infrared, with a peak absorption of light of 95% at 530 nm.

They are able to absorb a large fraction of visible light, with a reduced thickness. The most adopted structure is a bottom metal mirror, an oxide spacer, and an outer layer of Au nanoparticles, which Daniel Gomez pioneered using vacuum-based depositions - see here:

In this work, we present the fabrication of #plasmonic super absorbers using wet chemical methods, and their use as optical gas sensors. Super absorbers are nanostructures based on a mirror-spacer-nanoparticle architecture, and they function through optical interference and field localization.

Finally, we showcase the role of annealing temperature and atmosphere, achieving record photoelectrochemical performance for water oxidation.

This is very exciting, and we are now exploring doping and heterostructure formation, so heads up, more studies on this material are coming out soon!

First, we present a simple synthesis for CuWO4, highlighting the role that water plays in the complexation of metal ions within the precursor solution.

Then we discovered that Cu exhibits an unusually high oxidation state in CuWO4 (higher than +2), compensated with a reduced tungsten valency.

Thank you!

These optimal conditions allowed to increase the hematite thickness to improve light absorption, without affecting negatively charge transport across the material.

This study sets clear guidelines for producing high performance Fe2O3 photoanodes for sustainable #green #hydrogen production

In this work we present a simple, water based method to deposit phase-pure hematite Fe2O3 coatings for water oxidation.

Lead author Triet discovered a strong interplay between dopants and annealing conditions, finding an optimal combination to achieve high performance. 😲

Thanks Kevin!
