A Logic Gate Based on a Flexible Metal-Organic Framework (JUK-8) for the Concomitant Detection of Hydrogen and Oxygen

We present an autonomous, chemical logic gate based on a switchable metal-organic framework (MOF) composite, containing carbon nanoparticles and a Pt catalyst. The switchable MOF composite performs as AND logic gate. Hydrogen and oxygen gas streams serve as binary inputs. Catalytically formed water induces a structural transition (crystal volume expansion) of the MOF, and as a consequence, a detectable drop in conductance of the composite as a 'true' output only if both gases come in contact with the composite.

Automated summary

We present an autonomous chemical logic gate based on a switchable metal-organic framework (MOF) composite that functions as an AND gate. By using hydrogen and oxygen gas streams as binary inputs, the catalytic formation of water induces a structural transition of the MOF, resulting in a detectable drop in conductivity of the composite only when both gases come in contact with it.
