A TiO2 -Co(terpyridine)2 Photocatalyst for the Selective Oxidation of Cellulose to Formate Coupled to the Reduction of CO2 to Syngas.
Immobilization of a phosphonated cobalt bis(terpyridine) catalyst on TiO2 nanoparticles generates a photocatalyst that allows coupling aqueous CO2 -to-syngas (CO and H2 ) reduction to selective oxidation of biomass-derived...
A diketopyrrolopyrrole dye-based dyad on a porous TiO<sub>2</sub> photoanode for solar-driven water oxidation.
Dye-sensitised photoanodes modified with a water oxidation catalyst allow for solar-driven O2 evolution in photoelectrochemical cells. However, organic chromophores are generally considered unsuitable to drive the...

Solar H2 generation in water with a CuCrO2 photocathode modified with an organic dye and molecular Ni catalyst.
Dye-sensitised photoelectrochemical (DSPEC) cells have emerged in recent years as a route to solar fuel production. However, fuel-forming photocathodes are presently limited by photo-corrodible narrow band gap semiconductors or...
Solar-driven reforming of solid waste for a sustainable future
Approximately 70% of global municipal solid waste is lost to landfills or the environment each year, an emblem of our increasingly unsustainable economic system in which materials and energy are produced, used and promptly...
A diketopyrrolopyrrole dye-based dyad on a porous TiO2 photoanode for solar-driven water oxidation.
Dye-sensitised photoanodes modified with a water oxidation catalyst allow for solar-driven O2 evolution in photoelectrochemical cells. However, organic chromophores are generally considered unsuitable to drive the...
Photoreforming of biomass in metal salt hydrate solutions.
Metal salt hydrate (MSH) solutions allow for the complete solubilisation of biomass and we demonstrate its use as a reaction medium for the photocatalytic reforming of lignocellulose. Different types of photocatalysts such as...
Visible-Light Promoted C-O Bond Formation with an Integrated Carbon Nitride-Nickel Heterogeneous Photocatalyst.
Ni-deposited mesoporous graphitic carbon nitride (Ni-mpg-CNx ) is introduced as an inexpensive, robust, easily synthesizable and recyclable material that functions as an integrated dual photocatalytic system. This material...

Synthetic Organic Design for Solar Fuel Systems.
From the understanding of biological processes and metalloenzymes to the development of inorganic catalysts, electro- and photocatalytic systems for fuel generation have evolved considerably during the last decades. Recently...
Visible-Light-Driven CO2 Reduction by Mesoporous Carbon Nitride Modified with Polymeric Cobalt Phthalocyanine.
The integration of molecular catalysts with low-cost, solid light absorbers presents a promising strategy to construct catalysts for the generation of solar fuels. Here, we report a photocatalyst for CO2 reduction that consists...
Solar Hydrogen Generation from Lignocellulose.
Photocatalytic reforming of lignocellulosic biomass is an emerging approach to produce renewable H2 . This process combines photo-oxidation of aqueous biomass with photocatalytic hydrogen evolution at ambient temperature and...
