Titanosilicate ETS-10 derived from rice husk ash

A detailed characterization study on titanosilicate ETS-10 derived from rice husk ash (RHA) as silica source is reported. It can be prepared through a hydrothermal synthesis route in the absence of seed of ETS-4 and an organic template agent. The effect of different titanium source, crystallization...
