To gain deeper and more understanding the research on rice husk SiO2 in Indonesia, in this study, a bibliometric software VOSViewer was used to analysis relevant literature in the field. Scientific documents were retrieved from Scopus database between 1 January 2000 to 25 April 2023. Bibliometric indicators, including growth of publications, most prolific authors and institutions, most productive document sources, most cited papers, and cluster analysis were used and were presented using general statistic. Analyse results indicate that the number of documents on rice husk SiO2 in Indonesia have increased significantly, especially during the last seven years. Professor Wasinton and Lampung University were ranked first as the most prolific author and institution, respectively. Many documents have been published the IOP Conference Series Earth and Environmental Science and a document published in s. In addition, network analysis can be used to identify potential research collaboration among institute to address gaps and challenges, and to avoid unnecessary research overlap.

“…However, the silica precursors (TEOS and sodium silicate) are more expansive and less environment-friendly for synthesis of mesoporous silica (Manimaran, Tschentscher, Pandurangan, & Govindasamy, 2023). To address this issue, mesoporous silica was synthesized from various agro-derived sources, such as bamboo leaf ash (Arumugam, Karuppasamy, & Jegadeesan, 2018), rice husk ash (Bhagiyalakshmi, Yun, Anuradha, & Jang, 2010), corn cob ash (Dhaneswara et al, 2022), and stem cane ash (Azizi, Ghasemi, & Yazdani-Sheldarrei, 2013). Bamboo leaf ash (BLA) is a waste material found abundantly in India (Tamil Nadu) without cost of production.…”

Utilizing surplus glycerol from biodiesel production for dioxolane synthesis, a significant fuel enhancer, is pivotal. We developed mesoporous spherical KIT-6 supported WO3 using sodium silicate derived from bamboo leaf ash (BLA) and ammonium tungstate hydrate. Characterization via XRD, N2 adsorption-desorption, SEM, TEM, NH3-TPD, and XPS confirmed KIT-6's phase purity. WO3 impregnation on BLA-KIT-6 notably improved glycerol conversion and dioxolane selectivity compared to amorphous KIT-6 from tetraethyl orthosilicate (TEOS), primarily due to its advantageous spherical morphology. Spherical structures typically offer higher surface areas, facilitating more active sites for acid catalysis and thereby enhancing acidity. Additionally, glycerol conversion and dioxolane selectivity over the WO3/BLA-KIT-6 catalyst were higher with p-nitrobenzaldehyde due to its -M effect, while long chain aldehydes exhibited reduced conversion due to their + I effect. Conversely, cyclic ketones displayed heightened reactivity in glycerol acetalization over WO3/BLA-KIT-6 catalyst. Catalyst recyclability and hot-filtration tests verified its stability and heterogeneity. The Arrhenius plot yielded an apparent activation energy of 37.098 kJ/mol for the WO3/BLA-KIT-6 catalyst.
