On electron loss lowering at hematite photoelectrode interfaces Abstract: Photoelectrodes nanoscale interface design has become a key factor to enhancing their photoelectrochemical performance for water splitting by reducing the photogenerated charge recombination, thus ensuring their […]
BTEX gas sensor based on hematite microrhombuses Abstract: Over the past fifty years, gas sensors based on metal semiconducting oxides (MOXs) have drawn attention due to their performance in detecting various gases. Thus, we report […]
Unraveling the Role of Sn Segregation in the Electronic Transport of Polycrystalline Hematite: Raising the Electronic Conductivity by Lowering the Grain-Boundary Blocking Effect Abstract: This paper describes the role of SnO2 in the electronic transport of […]
Pristine and Al-doped hematite printed films as photoanodes of p-type dye-sensitized solar cells Abstract: We hereby propose a non-expensive method for the deposition of pure and Al-doped hematite photoanodes in the configuration of thin films for […]
Writers: Waldemir M. Carvalho Jr., Prof. Flavio L. Souza Abstract: In this study, the effect of tin (Sn4+) modification on the surface of hematite electrodes synthesized by an aqueous solution route at different times (2, 5, […]
Writers: Ricardo H. Gonçalves and Edson R. Leite Keywords: semiconductors; films; hematite ABSTRACT: Hematite is one of the most promising semiconductors used to convert solar irradiation directly into chemical energy (molecular hydrogen and oxygen) via water splitting. Although several methods […]
