111 oriented gold nanoplatelets on multilayer graphene as visible light photocatalyst for overall water splitting
Development of renewable fuels from solar light appears as one of the main current challenges in energy science. A plethora of photocatalysts have been investigated to obtain hydrogen and oxygen from water and solar light in the last decades. However, the photon-to-hydrogen molecule conversion is still far from allowing real implementation of solar fuels. Here we show that 111 facet-oriented go...
متن کاملEffect of high-pressure ammonia treatment on the activity of Ge3N4 photocatalyst for overall water splitting.
The photocatalytic activity of beta-Ge(3)N(4) powder for overall water splitting is successfully enhanced by ammonia treatment at 823 K for 5-24 h at ammonia pressures of 20 MPa or greater. The surface and bulk nitrogen content in the treated samples varies according to the treatment temperature and treatment time, related to the stability of beta-Ge(3)N(4) powder under pressurized ammonia. The...
متن کاملSynthesis of p-Co3O4/n-TiO2 Nanoparticles for Overall Water Splitting under Visible Light Irradiation
p-Co₃O₄/n-TiO₂ nanoparticles (~400 nm) for photocatalysis were prepared via carbon assisted method and sol-gel method in this work. The paper also studied the application of visible light illuminated p-Co₃O₄/n-TiO₂ nanocomposites cocatalyst to the overall pure water splitting into H₂ and O₂. In addition, the H₂ evolution rate of the p-Co₃O₄/n-TiO₂ nanocomposites is 25% higher than that of the p...
متن کاملA visible-light-induced overall water-splitting photocatalyst: conduction-band-controlled silver tantalate.
Visible-light-induced water splitting was achieved by increasing the visible-light sensitivity of AgTaO3, by the introduction of Nb, generating AgTa1-xNbxO3. After grafting NiO onto AgTa0.7Nb0.3O3, simultaneous, catalytic liberation of H2 and O2 at a molar ratio of ∼2 : 1 was achieved from pure water under only visible-light irradiation.
متن کاملAchievement of visible-light-driven Z-scheme overall water splitting using barium-modified Ta3N5 as a H2-evolving photocatalyst.
Ta3N5 is one of the most promising photocatalyst candidates for solar water splitting, but it still remains challenging to achieve overall water splitting via Ta3N5-based photocatalysts regardless of whether it uses a one step or two step method. Here we will address the relatively poor photocatalytic proton reduction of Ta3N5 with an effort for the promotion of charge separation via barium mod...
