Detailed description of the invention
Here will illustrate exemplary embodiment in detail, its example represents in the accompanying drawings.Explained below relates to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represents same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the present invention.On the contrary, they are only with the most appended
The example of the apparatus and method that some aspects that described in detail in claims, the present invention are consistent.
In the description of the present application, it should be noted that unless otherwise prescribed and limit, term " is installed ", " being connected ",
" connect " and should be interpreted broadly, for example, it may be mechanically connected or electrical connection, it is also possible to be the connection of two element internals, can
Being to be joined directly together, it is also possible to be indirectly connected to by intermediary, for the ordinary skill in the art, can basis
Concrete condition understands the concrete meaning of above-mentioned term.
Along with economic fast development and industrial expansion, not only can produce various in industry manufactures production process
The waste gas of various kinds, the most also can produce various gas at the various apparatuses made, and the generation of these gases not only can
Affect the use of instrument itself, and the potential threat of environmental pollution can be become.
Therefore, it is necessary to look for a kind of equipment that can monitor the gas that various apparatus in use produces, again may be used
Gas sensor with timely feedback monitoring to gas data.
The method of conventional detected gas is to gather gas at the scene, is stored in the sample devices of cleaning, is then sent to
Laboratory, uses the composition in the detected gas such as various instrument, such as GC, GC/MS or LC/MS and the problem such as quantitatively, but,
Above-mentioned detection method not only needs substantial amounts of sample collector to carry out spot sampling, consumes substantial amounts of manpower and materials, and at sample
In product transportation, it is frequently present of contaminated problem, delivers to the gaseous sample of laboratory and can not exist by reactor tool at all
Problem, maybe can not monitor its hazardness to environmental functional.
In existing report, there is employing inorganic material film and made gas detection sensor and carry out detected gas, but
That above-mentioned gas sensor there is problems in that the membrane material of employing is short for service life, and in the environment humidity bigger time
Wait, the most malfunctioning, it is impossible to well to play its effect.Therefore, need badly and find the one can be sensitive to hydrone, again on a large scale
Can monitor and separate the material of measured target gas station in time.
Metal-organic framework materials (MOFs) is the bonding mode and by coordinate bond by metal ion or metal cluster
A little organic ligands combine formation, due to metal ion or the difference of organic ligand, can show various topological structures.
MOFs self has that pore size is adjustable, specific surface area advantages of higher, and it is at gas-liquid separation, catalysis, optical, electrical, gas sensing etc.
Aspect has potential using value.Wherein HKUST-1 is a kind of typical metal-organic framework materials, and it is the quickest to hydrogen
Sense, when it contacts with hydrogen, the skeleton flexibility of HKUST-1 can become owing to sucking different guest molecules in duct
Changing, this change can cause again the change of its unit cell, and the change of unit cell eventually results in the change of HKUST-1 membrane resistance, logical
Cross and measure the concentration change reacting hydrogen to be measured that resistance can be sensitive.
The present invention, based on resistor-type HKUST-1 membrane material, designs hydrogen gas sensor, uses Cr film as the fork of sensitive blocks
Referring to electrode layer, Ni film is as the catalyst of HKUST-1 film forming.
The invention will be further described with the following Examples.
