“…In accordance with the literature, the CTAB amount plays a key role in the surface area of MSN. It has been reported that the surface area of MSN shows a tendency to increase along with the increasing CTAB concentration (0.5–4% CTAB) [ 30 , 39 , 41 ]. In addition, herein, the surface area was increased by increasing the CTAB amount.…”

The synthesis process or composition of mesoporous silica nanoparticles (MSNs) affects the physicochemical properties. Using these properties, MSNs were synthesized through the Box–Behnken design (BBD) among statistical experimental methods. The effect of the amounts of synthetic reagents, hexadecyl triethyl ammonium bromide (CTAB), tetraethyl orthosilicate (TEOS), and 2 N sodium hydroxide (NaOH), was studied using the reaction surface design. Surface area, particle size, and zeta potential were set as response values. The physicochemical properties of the optimized MSNs were evaluated, and the effect as a drug delivery system was evaluated by loading doxorubicin hydrochloride (DOX). Nano-sized MSNs were successfully prepared with 0.617 g of CTAB, 8.417 mL of TEOS, and 2.726 mL of 2 N NaOH and showed excellent physicochemical properties. The optimized MSNs showed negligible toxicity in MCF-7 cells. The drug release profile from DOX-loaded MSNs (MSN@DOX) showed an increased rate of release with decreasing pH of the medium, with the release profile sustained for 48 h. In the cytotoxicity test, the sustained drug release mechanism of MSN@DOX was confirmed. This study proposed a new statistical approach to the synthesis of MSNs.

“…All materials displayed the bending, asymmetric and symmetric stretching vibration band of siloxane (Si−O−Si) at wavenumber 464, 1242, 1071 cm −1 , respectively, as well as the symmetric stretching of silanol group at 965 cm −1 . On the other hand, the vibration bands appeared at 1636 cm −1 and 3450 cm −1 indicated the presence of O−H vibration band from adsorbed water on the surface of MS catalysts [10,13,16,18]. Furthermore, a distinction of spectrum was found in the vibration of MS before (SC) and after calcination.…”

Due to its wide application, synthesizing silica through a cost-effective process becomes an attractive subject to be studied today. In this work, mesoporous silica (MS) was prepared from the highly available agricultural waste, rice husk ash (RHA), to be used as catalyst in the pyrolysis of a-cellulose. Silica was extracted from RHA through a reflux process in a strong base solution and arranged into a mesoporous structure by using cetyltrimethylammonium bromide (CTAB). To find a condition that produces a mesoporous support with the highest surface area and catalytic activity, the mole ratios of CTAB:SiO2 used during the preparation of MS were varied; 0.05:1; 0.1:1; 0.2:1. Afterwards, all prepared MS were characterized using Fourier Transform Infra Red (FTIR), Scanning Electron Microscope (SEM), and Surface Area Analyzer (SAA). Through he surface area analysis, it was found that MS materials possessed surface area, pore diameter, and pore volume that range from 600–970 m2.g−1, 3.5–4.7 nm, 0.7–1 cm3.g−1, respectively. The highest surface area, with over 970.80 m2.g−1, was obtained in MS support prepared by using CTAB:SiO2 mole ratio of 0.1:1. SEM images showed a coral reef-like surface morphology for all MS. In the pyrolysis of a-cellulose evaluated by Py-GCMS, aside from producing biofuel compounds, the use of MS was able to generate two-fold furan production, which is considered as a valuable compound in many chemical syntheses. This result highlights the potential of MS prepared from RHA to be used as a catalysis support material that is more economical for biofuel and other chemical production.

“…7 In particular, the sol-gel method is popular as it is easy, less time-consuming (compared to other methods), has a low operational temperature, and is a more expedient process for synthesizing MMs. 8 Numerous chemical surfactants (e.g., CTAB, P123, F127, CTAC) play an important role in the synthesis of MMs with high specic surface area and desired shape comprising well dened structural morphology. 7,9,10 C 19 H 42 N + OH À /Cl À (a chemical surfactant) was used for the rst time to synthesize the mesoporous spherical material MCM-41.…”
