Modelling Photosynthesis

Synopsis

Asks if there is a way of capturing and storing the sun’s energy as useful chemical energy. In the photochemistry laboratories at the Royal Institution Sir George Porter outlines the aim - to find a way to split water into hydrogen and oxygen. Demonstrates the electrolysis of water and proceeds, via photoassisted cells, to Nozik’s diode, which splits water photochemically without the assistance of an electric current. Systems that use chlorophyll and chlorophyll analogues as the sensitiser are examined. Concludes by looking at the particle systems recently developed by Michael Gratzel. The programme contains many animation sequences to help explain the Redox diagrams and the electron transfer process.

Notes

NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
