Synthesis of Na-A and/or Na-X zeolite/porous carbon composites from carbonized rice husk
Na-A and/or Na-X zeolite/porous carbon composites were prepared under hydrothermal conditions by NaOH dissolution of silica first from carbonized rice husk followed by addition of NaAlO 2 and in situ crystallization of zeolites i.e., using a two-step process. When a one-step process was used, both N...

2 and in situ crystallization of zeolites i.e., using a two-step process. When a one-step process was used, both Na-A and Na-X zeolites crystallized on the surface of carbon. Na-A or Na-X zeolite crystals were prepared on the porous carbonized rice husk at 90
°C for 2–6

+-cation exchange capacity (CEC) of Na-A zeolite/porous carbon were found to be 171

meq/100
g, respectively, while those of Na-X zeolite/porous carbon composites were 676
m
2/g and 317

g, respectively. Na-A and Na-X zeolites are well-known microporous and hydrophilic materials while carbonized rice husk was found to be mesoporous (pores of ∼3.9
nm) and hydrophobic. These hybrid microporous–mesoporous and hydrophilic–hydrophobic composites are expected to be useful for decontamination of metal cations as well as organic contaminants simultaneously.
