ULTRAFAST AND ULTRASENSITIVE HYDROGEN SENSORS BASED ON SELF-ASSEMBLY MONOLAYER PROMOTED 2-DIMENSIONAL PALLADIUM NANOCLUSTERS

摘要

A device and method of making same. The device or hydrogen detector has a non­conducting substrate with a metal film capable of absorbing hydrogen to form a stable metal hydride. The metal film is being on the threshold of percolation and is connected to mechanism for sensing a change in electrical resistance in response to the presence of hydrogen in contact with the metal film which causes an increase in conductivity.
