Abstract
The new mesoporous silica modified with sulfanilic and sulfonic acids was synthesized by using rice husk ash (RHA) as the silica source. The solid catalysts were denoted as RHABzSO3H and RHAPrSO3H. The as-synthesized solid catalysts showed good textural and structural properties. The high–angle XRD diffraction pattern exhibited diffraction at 2θ which corresponds to amorphous silica.
Silika berliang meso baru telah terkini disintesis dengan mengubahsuai silica yang diperoleh daripada abu sekam padi (RHA) menggunakan asid sulfanilik dan asid sulfonik. Mangkin yang terhasil dilabel sebagai RHABzSO3H dan RHAPrSO3H. Mangkin yang disediakan mempunyai kualiti tekstur dan struktur yang baik. pembelauan XRD sudut tinggi menunjukkan pembelauan pada 2θ 22° yang menunjukkan sifat silika amorfus.
