TL;DR: The conformal deposition of an ultrathin p-type NiO layer on the photoanode is shown to create a buried p/n junction as well as to reduce the charge recombination at the surface trapping states for the enlarged surface band bending.

TL;DR: In this paper, the authors demonstrate a water-splitting reactor using a fixed Al-doped SrTiO 3 photocatalyst and address the key issues in the reactor design associated with the scaleup.

TL;DR: The proposed carbon-based photocatalyst sheet, which can be used at ambient pressure, is an important alternative to (photo)electrochemical systems for practical solar hydrogen production.

TL;DR: The photoelectrochemical properties of CuGaSe2 modified by deposition of a thin CdS layer showed high stability under the observed reaction conditions and evolved hydrogen continuously for more than 10 days.

TL;DR: A simple method allows the preparation of core/shell photocatalysts with spatially separated co-catalysts for efficient water splitting and the high activity was attributed to the core/ shell structure and separation and collection of the electrons and holes at the respective co-Catalysts.
