In natural photosynthesis, light is used for the production of chemical energy carriers to fuel biological activity. The re-engineering photosynthetic pathways can provide inspiration sustainable and insights understanding process itself. Here, we employ a semiartificial approach study photobiological water splitting via pathway unavailable nature: direct coupling oxidation enzyme, photosystem II, H2 evolving hydrogenase. Essential this integration isolated enzymes into artificial circuit...
Renewable, or green, hydrogen will play a critical role in the decarbonisation of hard-to-abate sectors and therefore be important limiting global warming. However, renewable is not cost-competitive with fossil fuels, due to moderate energy efficiency high capital costs traditional water electrolysers. Here unique concept electrolysis introduced, wherein supplied hydrogen- oxygen-evolving electrodes via capillary-induced transport along porous inter-electrode separator, leading inherently...
The electrochemistry of the Ru-containing polyoxometalate (POM) water oxidation molecular catalyst, Rb8K2[{Ru4O4(OH)2(H2O)4}(γ-SiW10O36)2]10− (Rb8K2-1), has been studied by cyclic and rotating disk electrode voltammetric methods in aqueous media under acidic neutral pH conditions using bare glassy carbon (GC) graphene modified GC electrodes. High concentrations supporting electrolyte are needed to overcome electrical double layer effect associated with highly negatively charged 1. Complex 1...
We prepared mesoporous α-Fe2O3/FTO electrodes by a simple anodic precipitation and annealing method. The classic problem is that when annealed in air at >500 °C, the individual particle size increases from ≈20 nm to 40–60 nm. This grain growth highly detrimental for water splitting efficiency. In present work we show coarsening can efficiently be prevented two-step method Ar, leading photocurrent densities such (obtained 1 M KOH solution) of up 2.6 mA cm−2 1.6 V vs. RHE under AM 1.5 100 mW...

Abstract Control over the topography of semiconducting materials can lead to enhanced performances in photoelectrochemical related applications. One means implementing this is through direct patterning metal‐based substrates, though inadequately developed. Conventional techniques for patterned fabrication commonly involve technologically demanding and tedious processes. 3D printing, a form additive fabrication, enables creation object by deposition successive layers material via computer...
A p-type heterojunction photoelectrode consisting of platinized CuBi2O4 layered on a CuO film was prepared. The CuO|CuBi2O4|Pt electrode photo-generates H2 in pH neutral aqueous solution during visible light irradiation and exhibits substantially enhanced photocurrent compared to CuO|Pt CuBi2O4|Pt electrodes. Reduced electron-hole recombination by the band offsets heterostructure is responsible for improved photoelectrochemical performance CuO|CuBi2O4 with small band-gap approximately 1.5 eV.
Nanoporous materials: High-aspect-ratio, ordered porous Co3O4 layers were formed by self-organizing anodization of a cobalt substrate and subsequent annealing. The key for successful formation such is to sufficiently suppress competing oxygen evolution during anodization. aligned channel behave as highly efficient water oxidation catalyst (see picture). As service our authors readers, this journal provides supporting information supplied the authors. Such materials are peer reviewed may be...
