“…As an alternative, high FFA oil can be produced as biodiesel in dual steps: first, it is esterified employing a homogeneous acid catalyst like H 2 SO 4 and HCl and then it is transesterified using a base catalyst. However, the reactor is vulnerable to corrosion and has elevated manufacturing expenses because of the necessity of a further treatment step and the extremely concentrated acid catalyst . The major difficulties related to homogeneous catalysts include problems of separation and purification of products, formation of soap, and overflowing wastewater owing to excessive washing of biodiesel, which hinders their application in biodiesel production.…”

The increasing global population and its associated energy requirements significantly burden natural energy resources. The Paris Agreement's promises to prevent global warming and promote sustainable development are obscured by the fossil fuel industry's frightening rate of exploitation. Biodiesel offers a sustainable substitute for fossil fuels to solve viable fuel and socioeconomic issues. Diverse feedstocks, including Jatropha oil, palm oil, used frying oil, edible oil, animal fat, and microbial oil, are used to make biodiesel. Much exploration has been done on creating innovative and sustainable biodiesel synthesis technologies to boost the yield of biodiesel to remain competitive. In the current investigation, tamarind seed (Tamarindus indica) derived sulfonated doped carbon catalyst was utilized for the transformation of used cooking oil methyl ester (UCOME). The morphological and spectral analyses of the produced catalyst were performed thoroughly by means of TGA, BET, FTIR, XRD, and SEM-EDAX. The study of optimization of parameters that impact biodiesel efficacy was conducted using response surface methodology, which gave 98.97% conversion. The esterification reaction was examined by two kinetic models, and it followed the pseudo-first-order reaction kinetics with the reaction being endothermic and not spontaneous. The catalyst exhibited good reusability with 81.17% conversion until 4 cycles. The deactivation study of the prepared sulfonated catalyst (SDC) was analyzed. Additionally, fuel was ascertained by GC−MS, 1 H NMR, and FTIR evaluations. The anticipated cost of 1 kg catalyst and 1 L UCOME, as determined by cost analysis, were $3.706 and $0.403, respectively, demonstrating their excellent economic viabilities.

The growing population and the unpalatable ecological impact of exploration and utilization of fossil-based fuels have resulted in increased demand for biofuel as an alternative fuel for engines and power generation. The global demand for biodiesel, a prominent member of the biofuels family, has continued to increase over the past decades with researchers devising various means to intensify cost-effective production. The use of metal oxide nanocatalysts is one of the feasible strategies to meet the increased demand for quality biodiesel. This study reviews the recent advances in the deployment of commonly used metal oxide nanoparticles such as MgO, CaO, TiO2, ZnO, and ZrO2 to accelerate sustainable biodiesel production. Converting conventional metal oxide heterogeneous catalysts into nanoparticles enhances the surface configuration, chemical and thermal stability, porosity, and crystallinity of the nanocatalysts. The deployment of metal oxide nanocatalysts hasten the transesterification reaction, reduces reaction temperature and time, and enhances biodiesel yield. Biodiesel synthesized with the aid of metal oxide nanoparticles is of impeccable quality and meets international standards. Notwithstanding the few challenges, the application of metal oxide nanoparticles as heterogeneous catalysts engenders sustainable biodiesel production and contributes to energy security. More innovative and collaborative studies are needed to reduce the ethical, economic, infrastructural, and environmental consequences of the usage of nanomaterials for sustainable biodiesel production.
