“…In photocatalyst, particle size become an important factor that is able to in uence the activity of photocatalysts. The surface structure and shape of crystals can be a ected by (Pieła et al, 2020) particle size (Cao et al, 2016;Hwang et al, 2017). Research conducted by Lin et al, 2006 successfully synthesized TiO 2 nanoparticles of di erent particle sizes (12-29 nm) and found their in uence on ribbon gaps indicating that particle size is capable of a ecting the electro-optical properties of photo.…”

“…So far, a great deal of research have been conducted on silica as a supporting material for antibacterial photocatalysis (Zemnukhova et al, 2015;Carmona et al, 2013;Permatasari et al, 2016;Ramanathan et al, 2020;Olawale, 2020;Pieła et al, 2020). However, the silica used was synthetic as was conducted by Hou et al, 2018, in making SiO 2 mesoporous spherical particles that were coated separately with Ag 2 O, Cu 2 O, CeO 2 , and NiO nanoparticles and used for 26 antibacterial applications.…”

Silica has become a popular material due to its high abundance and many advantages in various fields. This material can be produced synthetically and extracted from nature with resultant advantages in the application of green production. Therefore, this article deals with the form of silica extracted from quartz sand, leaves, and agricultural wastes found in nature. The extraction process from various sources would be described using thermal, biological, and chemical methods. This review also highlights the potential application of silica as a photo catalytic antibacterial-supporting material and discusses its role in increasing the effectiveness of the process. The discussion was continued with research on this procedure, where synthetic auxiliary materials were compared to the extracted silica. Furthermore, results obtained indicated that the extracted material had very good potential as a photocatalyst adjunct in its application in the antibacterial field.

“…For example, they tried to use agricultural biomass waste as raw material to obtain silica. Silica powder practically can be obtained from the extraction of sugarcane bagasse [10], rice husks [3,5,[11][12][13], corn cobs husks [1,14], palm kernel shell [4,[15][16][17], oil palm fronds [18,19], and others. Imoisili et al (2020) did extraction of palm kernel shell ash using the sol-gel technique to produce amorphous silica with a purity of 56.65% [4].…”

Silica (SiO2) can be extracted from rice husks and has biodegradable properties. However, the rice husk extraction process using the sol-gel technique generates low-purity silica, making them non-compliant as a filler material on the rubber finished goods industry. This study aimed to improve the characteristics of silica particles extracted from rice husks using the leaching-pyrolysis technique compared to the sol-gel technique. Silica was extracted from rice husks using 1.0 N sodium hydroxide and hydrochloric acid solvent (with concentrations of 0.4 N, 1.0 N, and 2.0 N). The pyrolysis was then conducted at 600 °C for 6 hours. The results showed that the leaching-pyrolysis technique was more effective than the sol-gel technique in improving silica particle characteristics. X-ray fluorescence analysis showed that the SiO2 content increased from 91.00 % to 96.82 %. Likewise, the percentage of amorphous by X-ray diffraction analysis and specific surface area by the Brunauer Emmett-Teller method also increased, namely from 48.20 % to 53.97 % and from 96.486 m2/g to 240.427 m2/g, respectively. Therefore, silica from rice husks with these characteristics is applicable as a filler material that is environmentally friendly and renewable.

Combustion of corn leaf as a model of biomass from agricultural waste is a simple way to obtain the energy. It produces a low-value by-product of ash and is rich in silica that can become a precursor for zeolite production. In this study, acid-treated corn leaves combustion was performed to produce high purity silica (SiO2). The diffraction pattern suggested that the extracted silica was amorphous without the impurities phase. Additionally, the nitrogen isotherm indicated that the material was highly mesoporous silica with a total surface area of 200 m2/g. The hydrothermal method was then applied with a composition molar ratio of 1.25SiO2:1Al2O3:5Na2O:250H2O to synthesize zeolites from the silica. The temperature and time effect on the hydrothermal zeolite’s synthesis was investigated. The diffraction pattern shows that high crystalline zeolite Na A-X was produced at temperatures of 100°C and 8 h hydrothermal time. According to nitrogen physisorption analysis, the zeolite Na A-X consisted of micropores with a total surface area of 270 m2/g. The morphology of zeolite Na A-X was cube for the Na-A and octahedral for the Na-X. The hydrothermal temperature and time highly affected the zeolite formed. This research suggested that the ash waste could be valorized through conversion into a high economic value zeolites.
