Embodiment 1

[0065] Low pressure (0-1 atmosphere) argon adsorption measurement of polytetraphenylene silicon and polytetraphenyl germanium at 87K:

[0066] The polytetraphenyl silicon and polytetraphenyl germanium samples were soaked in chloroform and stirred, filtered after half an hour, replaced with new chloroform, and reciprocated four times to remove the solvent and aerosol included in the pores of the material during synthesis. starting material. Load the processed material into an ampoule, then heat it to 80-200°C for 4-40 hours under an oil pump (vacuum degree less than 10-3 mmHg) and vacuumize for 4-40 hours, and backfill the sample with nitrogen to exclude the adsorption of argon Moisture sorption prior to measurement.

[0067] The provided polytetraphenylsilicon and polytetraphenylgermanium have functionalized pores and high specific surface area, which in this example act as adsorbents for argon. Unlike nitrogen, because argon is an inert molecule and is spherical, this kind ...

Description

technical field [0001] The invention relates to the field of functional materials, in particular to a gas storage device using a porous organic material with a high specific surface area and a device for absorbing chemical species. Background technique [0002] With the advancement of science and technology, human society has experienced three energy stages of firewood, coal and oil. Judging from the energy structure of the future society, on the one hand, human beings will encounter the depletion of mineral energy resources such as coal and oil, and on the other hand, they have already faced up to the profound environmental problems caused by mineral energy. Faced with the severe challenge of energy, all countries are aware of the importance, necessity and urgency of energy transition, and have put forward action plans for energy transition based on their actual conditions, and strengthened the development, promotion and application of new energy. The energy system compose...
