“…Similarly, WCO was utilized for the FAME production using ferricmanganese doped tungstate molybdena nanoparticles (FMWMo). 338 The Fe-Mn dopants enhance the surface area, density of acidic sites, and the stability towards the esterication of WCO. A maximum yield of 92.3 AE 1.12% methyl ester was achieved under the optimized reaction conditions.…”

“…Using 10 wt. % of the catalyst and a reaction temperature of 160°C, a 92.3 % FAMEs yield was obtained after 12 h. Alhassan et al [52] synthesised a ferricmanganese-promoted molybdenum oxide/zirconia nanoparticle solid acid catalyst (Fe-Mn-MoO 3 -ZrO 2 ) for the preparation of FAMEs from waste cooking oils by reaction with methanol. In their work, a catalyst loading of 6 wt.%, a reaction temperature of 200°C and a reaction time of 4 h gave a 95 % FAME yield.…”

Hydrothermal carbonisation was used to synthesise hydrothermally ordered mesoporous carbon (HOMC), employing sucrose as the carbon source, a P123 block copolymer as the surfactant and tetraethyl orthosilicate as the silicon source. A high-density sulfonic-acid-based solid acid catalyst (HOMC-SO 3 H) was subsequently prepared via low-temperature sulfonation of the HOMC with concentrated sulfuric acid. Transmission electron microscopy and small-angle X-ray diffraction analyses showed that both the HOMC and HOMC-SO 3 H exhibited an ordered mesoporous structure. The N 2 Brunauer-Emmett-Teller surface areas of the HOMC and HOMC-SO 3 H were determined to be 112 and 87 m 2 /g, respectively, and the average pore sizes were 11.0 and 15.1 nm, respectively. X-ray photoelectron spectroscopy data confirmed that À SO 3 H groups were successfully introduced onto the HOMC surface by the sulfonation process, and a surface acid concentration of 5.9 mmol/g HOMC-SO 3 H was determined by acid-base titration. The HOMC-SO 3 H was applied to the transesterification of waste frying oil with methanol and a fatty acid methyl ester yield of 95 % was obtained after a 5 h reaction at 180°C.

<p>An ever-increasing energy demand and environmental problems associated with exhaustible fossil fuels have led to the search for an alternative renewable source of energy. In this context, biodiesel has attracted attention worldwide as an alternative to fossil fuel for being renewable, non-toxic, biodegradable, carbon-neutral; hence eco-friendly. Despite homogeneous catalyst has its own merits, currently, much attention has been paid to chemically synthesize heterogeneous catalysts for biodiesel production as it can be tuned as per specific requirement, easily recovered, thus enhance reusability. Recently, biomass-derived heterogeneous catalysts have risen to the forefront of biodiesel productions because of their sustainable, economical and eco-friendly nature. Further, nano and bifunctional catalysts have emerged as a powerful catalyst largely due to their high surface area and potential to convert free fatty acids and triglycerides to biodiesel, respectively. This review highlighted the latest synthesis routes of various types of catalysts including acidic, basic, bifunctional and nanocatalysts derived from different chemicals as well as biomass. In addition, the impacts of different methods of preparation of catalysts on the yield of biodiesel are also discussed in details.</p>
