Title:
MICRO-POROUS HOLLOW NICKEL OXIDE GAS-SENSITIVE MATERIAL FOR SELECTIVELY ADSORBING FORMALDEHYDE AS WELL AS PREPARATION AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/103145
Kind Code:
A1
Abstract:
A micro-porous hollow nickel oxide gas-sensitive material for selectively adsorbing formaldehyde as well as preparation and application thereof, the preparation comprising: dispersing nanocellulose into a mixed solution of de-ionized water and a dispersant; adding a nickel precursor and a slow-release precipitant hexamethyl tetramine after completely dispersing the nanocellulose; placing a beaker full of the solution into a drying oven to heat and carry out reacting so as to obtain a green precipitate; and placing the green precipitate into a crucible to carry out high-temperature calcination so as to obtain the micro-porous hollow nickel oxide gas-sensitive material after cleaning and drying the green precipitate. The prepared nickel oxide may be used for selective detection of formaldehyde gases in the air.
