The electronic structure of nanowires, nanotubes and thin films deposited on a substrate is varied by doping with electrons or holes. The electronic structure can then be tuned by varying the support material or by applying a gate voltage. The electronic structure can be controlled to absorb a gas, store a gas, or release a gas, such as hydrogen, oxygen, ammonia, carbon dioxide, and the like.
