Mesoporous Composite Materials from Acivated Rice Husk Carbon and Montmorillonite
Three different carbons were prepared from rice husk by steam activation at 700 ºC, H3PO4-activation followed by desilication or desilication followed by H3PO4-activation at 500 ºC. Honeycomb monoliths were obtained by mixing of a carbon with montmorillonite followed by extrusion, curing, calcinatio...
