1. Cov kab mob ceev ceev: lub nplhaib-mounted tsim, zoo yaj oxygen.
2. Zoo hydrophilicity: thaj chaw microporous kab lis kev cai yog qhov loj, kev hloov dej nrawm nrawm, kev ua haujlwm lom neeg muaj siab, thiab cov nyhuv dej huv yog qhov zoo.
3. Tsis yooj yim rau pulverize: kub kub firing, me me, lub teeb yuag, ruaj qauv, tsis yooj yim rau pulverize.
4. Cov khoom siv lim dej tsis zoo: Cov dej tsis zoo yog qhov ruaj khov hauv pH, thiab nws tsis yooj yim los cuam tshuam qhov hloov pauv ntawm lub cev dej.5. Muaj zog adsorption: dej permeability siab thiab muaj zog adsorption.
