“…However, this interaction should be adjustable to be irreversible (in the case of immobilization) or reversible to allow leaching and recovery of protein under different pH and ionic strength. With this regard, several studies have demonstrated the effect of pH and ionic strength on the adsorption capacity of several types of adsorbents [43,44]. Normally, the maximum adsorption capacity occurs close to the isoelectric point (pI) of biomolecules [45][46][47].…”

“…SBA-15 and SBA-16 were bind together with graphite powder via the help of paraffin oil (Figure 1c and Figure 1d). [24,25] in which it shows three resolved peaks at lower angle 2Ɵ= 0.5-2.5ᵒ which are indexed to (100), (110), and (200) that reflects as the well-ordered mesoporous silica, SBA-15 [26]. As evidence that SBA-16 materials possess a cubic ordering, three peaks of (110), (200), and (211) appears in diffractogram b [27].…”

Mesoporous silica of SBA-15 and SBA-16 were successfully synthesized via the surfactant templating technique using tetraorthosilicate (TEOS) as the silica source and both surfactants, pluronic P123 and F127. Two different modified carbon paste electrodes (MCPE) were fabricated; SBA-15/MCPE and SBA-16/MCPE in compared to unmodified electrode, carbon paste electrode (CPE), for ascorbic acid (AA) and uric acid (UA) determination. Due to the unique properties of mesoporous silica materials, the MCPE fabricated exhibits greater surface enhancement effect, offers better adsorption and increases the response signals of AA and UA towards both MCPEs compared to CPE. The electrochemical behaviours of AA and UA were investigated using cyclic voltammetry. Finally, the electrochemical methods were successfully applied in detection of AA and UA.Keywords: mesoporous silica, electrochemical sensor, SBA-15, SBA-16, synthesis, electrochemical methods AbstrakMesoporus silika SBA-15 dan SBA-16 telah disintesis dengan jayanya melalui teknik templat surfaktan menggunakan tetraortosilikat (TEOS) sebagai sumber silika dan kedua-dua surfaktan, Pluronic P123 dan F127. Dua elektrod pes karbon yang dimodifikasi (MCPE) yang berbeza, SBA-15/MCPE dan SBA-16/MCPE telah dihasilkan dan dibandingkan dengan elektrod pes karbon yang tidak dimodifikasikan (CPE), untuk penentuan asid askorbik (AA) dan asid urik (UA). Dengan sifat-sifat unik bahan silika, MCPE yang telah difabrikasi mempamerkan peningkatan efek permukaan yang baik, penjerapan yang lebih bagus, dan peningkatan signal respon AA dan UA terhadap kedua-dua MCPE berbanding CPE. Perlakuan elektrokimia AA dan UA telah dikenalpasti dengan menggunakan alat voltametri berkitar. Akhirnya, kaedah elektrokimia telah berjaya diaplikasikan dalam pengesanan AA dan UA.

Effect of pore geometry of mesoporous supports on catalytic performances in methane reforming

Abstract-Catalysts prepared using three dimensional SBA-16 silica support (composed of micropores and cage-like mesopores) were tested in the reaction of methane dry reforming, in comparison with 2D hexagonal mesoporous SBA-15 support. The samples were evaluated by N2 sorption and X-Ray diffraction (XRD) for the assessment of their textural and structural properties. The reducibility was characterized by temperature programmed reduction (TPR). The catalytic performances were evaluated in methane dry reforming and spent catalysts (after reaction) were characterized for the evaluation of sintering and coke formation by TPH/MS, XRD and HR-TEM.
