Introduction

free download acronis true image 2010 keygen Photo-electrochemical production of hydrogen from water using solar energy and suitable energy conversion systems offers a potential route to a sustainable, carbon-free energy vector. The principal considerations in the design of such systems are materials and reactor structure. Our research is focused on these micro- and macro- aspects in parallel and our goal is to build a prototype device that can successfully demonstrate the spontaneous splitting of water into hydrogen and oxygen upon illumination by solar photons. 

Project aims 

los sims 3 android cracked The project aims to model, design, fabricate, characterise, and optimise innovative, low-cost, reactors with stable photo-electrodes for hydrogen production from water, driven by solar energy.

We successfully employed tinkeyfinder crack IV-doped hematite photo-anodes, coupled to a platinised titanium cathode in a system for assisted solar water splitting. Presently our work is focused on coupling the hematite photo-anodes with photo-cathodes for spontaneous solar water splitting in a novel photo-electrochemical demonstration reactor.

Photo-electrochemical reactor

lfs s2 alpha 0.5 z crack The principal considerations in the design of a photo-electrochemical reactor are:

  • Optimisation of the mechanism for the illumination of both photo-electrodes;
  • Minimisation of ohmic losses between the photo-electrodes, as well as current density distributions across the photo-electrode surfaces;
  • Efficient separation of the gaseous products of the water splitting process, minimising crossover;
  • Effective capture of hydrogen, enabling accurate quantification of the solar to hydrogen conversion efficiency.

Reaction and reactor modelling

robot structural analysis 2013 full crack Finite element numerical models have been developed of both semiconductor | solution interfaces and of complete reactors to understand:

  • The factors controlling kinetics of Fe2O3 photo-anodes, leading to enhancement of photocurrent densities, quantum yields and energy conversion efficiencies;
  • Spatial distributions of electrical potentials, (photo-) current densities and local dissolved hydrogen and oxygen concentrations;
  • Distributions of local fluid velocities in the reactor and their effects on local reactant and product concentrations, to enable improved reactor design and to relax scale-up limitations.
