Turning rice husk (RH) into silica nanoparticles (SiNPs) is a potential strategy for valorization of rice shelling waste. In this study, SiNPs were synthesized from RH of three Basmati (BcvSiNPs) and six Parmal rice varieties (PcvSiNPs) using physico-chemical approach. The average size of BcvSiNPs and PcvSiNPs varied from 20 to 80 nm and 10 to 60 nm respectively, with occurrence of spherical to irregular-shaped aggregates (up to 200 nm) in the former and quasi-spherical to hexagonal shapes in the latter. The SEM-EDS study indicated higher silicon-content in BcvSiNPs compared to PcvSiNPs. However, FTIR analysis of SiNPs accentuated the presence of similar functional groups for both types.

Abstract


Turning rice husk (RH) into silica nanoparticles (SiNPs) is a potential strategy for valorization of rice shelling waste. In this study, SiNPs were synthesized from RH of three Basmati (BcvSiNPs) and six Parmal rice varieties (PcvSiNPs) using physico-chemical approach. The average size of BcvSiNPs and PcvSiNPs varied from 20 to 80 nm and 10 to 60 nm respectively, with occurrence of spherical to irregular-shaped aggregates (up to 200 nm) in the former and quasi-spherical to hexagonal shapes in the latter. The SEM-EDS study indicated higher silicon-content in BcvSiNPs compared to PcvSiNPs. However, FTIR analysis of SiNPs accentuated the presence of similar functional groups for both types.
