Yes - this is very good news for many potential energy applications - the problem being: is platinum absolutely necessary? There are a number of exotic cold cathode materials already in mass production - going back to one of the great unsung heroes of invention: Philo Farnsworth. Here is

Semiconductor coating lowers the work function of metal plates: http://focus.aps.org/story/v6/st3 If this effect can be combined with field emission from points that are covered with the semiconductor as they are exposed flush with a flat composite matrix of embedded consistent diameter
