ControllablePreparation and Properties of mesoporous nickel oxide / carbon composite
Abstract:Mesoporous carbon materials with large specific surface area and pore volume and pore size , has important applications in electrochemical capacitors , such as supercapacitors.This subject is an evaporation method using a surfactant F127 , nickel nitrate ( hexahydrate ) as precursor , TEOS as the silicon source , Resol carbon precursor,ethanol as the reaction solution was gradually mixed to obtain homogeneous solution.After the normal temperature and the temperaturecrosslinking for inorganic and organiccompounds, further by inert atmosphere roasting to obtain mesoporous composite NiO/SiO2/Cand then removed with a sodium hydroxide solution to obtain mesoporous silica NiO/C composites. Through a small Angle XRD mesoporous properties of test samples,Large Angle of a crystallization of the XRD test samples,Nitrogen adsorption test samples of specific surface area, pore diameter, etc, nergy spectrum test the element type of the sample,and the last part electrochemical performance test.
