From: Experimental investigation of porous carbon for cooling and desalination applications

a SEM image of raw Max, b SEM image of Max/HCl, c SEM image of Max/(NH4)2CO3, d XRD of Max samples, and e N2 adsorption-desorption isotherms of raw and modified Max. No change can be observed Max structure. Max N2 isotherms are closest to the I-Type, and the Max has microporous pore sizes.
