Series II | Episode 7

In this science-themed episode, Regius Professor Graham Hutchings tells his story of scientific discovery. Since the 1970s, Prof. Hutchings has been a key player in the field of heterogeneous catalysis. 

Gold metal was always thought to be a very inactive metal, with no other uses than as a material for fine jewellery.
