Reactivity of rice husk-derived lithium silicates followed by in situ Raman spectroscopy
(Elsevier Science Sa, 2019-03)
Lithium silicates were synthesized using rice husk ash as a precursor of silica to be used in CO2 capture. Two different treatment steps, with water (SiO2-W) or HCl 3 M (SiO2-A), were carried out prior to the rice husk ...

Cement is the construction building material with higher responsibility by carbon dioxide emission of all industrial human activities, besides be a considerably expensive material, more than the rice husk ash in nature. ...
Optimization of slow pyrolysis process parameters using a fixed bed reactor for biochar yield from rice husk
(2020-01-01)
A fixed bed reactor has been used to assess the influence of slow pyrolysis process parameters on biochar yield from rice husk. Taguchi's method (L9) was used for such a purpose, which four parameters varied according to ...
Sunlight photoactivity of rice husks-derived biogenic silica
(2019-05-15)
Carbon-containing SiO 2 -based photocatalysts were prepared by the solvothermal treatment of rice husk as biogenic precursor in the presence and absence of TiO 2 and used for the photocatalytic degradation of rhodamine-B ...
