    Abstract: A gas diffusion layer having a first major surface and a second major surface which is positioned opposite to said first major surface and an interior between said first and second major surfaces is formed. The gas diffusion layer comprises a porous carbon substrate which is directly fluorinated in the interior and is substantially free of fluorination on at least one of the first major surfaces or the second major surfaces, and preferably both surfaces. The gas diffusion layer may be formed using protective sandwich process during direct fluorination or by physically or chemically removing the C—F atomic layer at the major surfaces, for example by physical plasma etching or chemical reactive ion etching.

    Abstract: Provided are FeS2 based photovoltaic battery devices comprising a transparent substrate, an active layer disposed over the transparent substrate, the active layer comprising a porous film of FeS2 nanocrystals and a halide ionic liquid infiltrating the porous film, and an electrode disposed over the active layer. The device may be configured such that under exposure to light, photons incident on the active layer are absorbed by the FeS2 nanocrystals, generating a current and a voltage, whereby a separation of charge within the active layer is created, which is discharged in the absence of the light.

    IPC: C25B1/00

    CPC classification number: C25B1/003

    Abstract: A method for making a metal oxyhydroxide electrocatalytic material comprises titrating a precursor solution with a (bi)carbonate salt, the precursor solution comprising a first metal salt and a solvent, wherein the titration induces reactions between the (bi)carbonate salt and the first metal salt to provide first metal carbonate species in the titrated precursor solution; and exposing the titrated precursor solution to microwave radiation to decompose the first metal carbonate species to form the metal oxyhydroxide electrocatalytic material and carbon dioxide. Mixed metal oxyhydroxide electrocatalytic materials such as nickel-iron oxyhydroxide may be formed. Also provided are the materials themselves, electrocatalytic systems comprising the materials, and methods of using the materials and systems.
