The behavior of catalysts that promote chemical reactions is not always straightforward. For example, adding oxygen enhances some catalytic oxidation reactions (reactions that introduce oxygen ...

The sensor is made from nano-patterned polycrystalline CuO NWs, which are highly sensitive to hydrogen gas, placed on a silicon (SiO 2 /Si) substrate with platinum/titanium electrodes.
