Journal ArticleDOI
Probing the photoelectrochemical properties of hematite (α-Fe2O3) electrodes using hydrogen peroxide as a hole scavenger
TL;DR: In this article, the fate of photogenerated holes in photoelectrodes for water splitting was examined using H2O2 as an efficient hole scavenger, and all holes that arrived at the electrode/electrolyte interface were collected.
Journal ArticleDOI
Ultrasensitive chemiresistors based on electrospun TiO2 nanofibers.
TL;DR: TiO2 nanofiber sensors tested for NO2, in dry air, exhibited exceptional sensitivity showing with, for example, a 833% increase in sensor resistance when exposed to 500 ppb NO2 at 300 degrees C, consistent with a detection limit estimated to be well below 1 ppb.
Journal ArticleDOI
The effect of grain size on the sensitivity of nanocrystalline metal-oxide gas sensors
Avner Rothschild,Y. Komem +1 more
TL;DR: In this article, the effect of grain size on the sensitivity of chemoresistive nanocrystalline metal-oxide gas sensors was evaluated by calculating the effective carrier concentration as a function of the surface state density for a typical sensing material, SnO2, with different grain sizes between 5 and 80 nm.
Journal ArticleDOI
Identifying champion nanostructures for solar water-splitting
Scott C. Warren,Scott C. Warren,Kislon Voïtchovsky,Hen Dotan,Céline M. Leroy,Maurin Cornuz,Francesco Stellacci,Cécile Hébert,Avner Rothschild,Michael Grätzel +9 more
TL;DR: In correlating structure and charge transport with nanometre resolution across micrometre-scale distances, this work has identified the existence of champion nanoparticle aggregates that are most responsible for the high photoelectrochemical activity of the present electrodes.
Journal ArticleDOI
Ultrasensitive and Highly Selective Gas Sensors Based on Electrospun SnO2 Nanofibers Modified by Pd Loading
TL;DR: In this article, a new route to suppress grain growth and tune the sensitivity and selectivity of nanocrystalline SnO2 fibers was presented, where the Pd-loaded sensors have 4 orders of magnitude higher resistivity and exhibit significantly enhanced sensitivity to H2 and lower sensitivity to NO2 compared to their unloaded counterparts.
