Formation of nickel hydrides in reactive plasmas

Abstract

The behaviour of hydrogen in metals has attracted scientific attention for many decades and is interesting from both basic research and technological points of view. Metal hydrides find a wide range of applications of which the most prominent is the reversible hydrogen storage. This is of great importance in view of possible future hydrogen economy. Moreover the high diffusivity of hydrogen also makes nanoscaled Me-H systems interesting possibilities for sensor applications, and surface reactions with hydrogen on Pt, Pd, Ni, and other metals are applied in catalysis, particularly in fuel cells.
