Activated carbon derived from peat soil as a framework for the preparation of shape-stabilized phase change material

摘要: Abstract This work focuses on the preparation of AC (activated carbon) through a physical activation method using peat soil as precursor, followed by use an inorganic framework for SPCM (shape-stabilized phase change material). The SPCM, composed n-octadecane core and pores framework, was fabricated simple impregnation method, with mass fraction varying from 10 to 90 wt.%. has specific surface area 893 m 2  g −1 average pore size 22 A. field emission scanning electron microscope images nitrogen gas adsorption-desorption isotherms shows that actually encapsulated into pores. melting freezing temperatures composite PCM (phase material) were 30.9 °C 24.1 °C, respectively, its corresponding latent heat values 95.4 Jg 99.6 Jg , respectively. good thermal reliability, even after 1000 melting/freezing cycles. present research provided new material energy storage well some insights design tailoring structure derived soil, natural resource.
