“…The XRD pattern of nanocellulose ( Figure 3 a) featured peaks at 2 θ = 16°, 22° (most intense), and 35°, corresponding to reflections from the (101), (002), and (040) planes [ 46 ], respectively. These data were in line with the results of our previous studies [ 13 , 27 , 43 ]. The diffraction pattern of α-Fe 2 O 3 ( Figure 3 b) featured peaks at 2 θ = 25.3°, 33.5°, 36.3°, 40.3°, 50.2°, 55.2°, 57.8°, 63.5°, 65.2°, and corresponding to the (012), (104), (110), (113), (024), (116), (122), (214), and (300) planes of Fe 2 O 3 , respectively.…”

“…Several catalysts with nanocellulose as a support and inorganic compounds as active ingredients have been synthesized for biodiesel production [ 26 , 27 ] Nonetheless, very few studies have evaluated the effect of nanocellulose supports on the catalytic activities of nanohematite and nanozirconia. To bridge this gap, the present study probes the effect of nanocellulose loading on the performance of cellulose@ α-Fe 2 O 3 –ZrO 2 nanocomposites for biodiesel production from lauric acid.…”

The depletion of fossil fuels calls for the development of renewable alternatives such as biodiesel and has inspired much research on catalysts for the production of biodiesel through the esterification of biomass-derived materials. Herein, a green heterogeneous catalyst for highly efficient biodiesel synthesis was fabricated from rice straw–derived cellulose, hematite, and zirconia and was shown to contain porous irregularly shaped α-Fe 2 O 3 –ZrO 2 composites (average particle size = 42.5 nm) evenly distributed on the nanocellulose surface. The optimal catalyst (nanocellulose:α-Fe 2 O 3 –ZrO 2 = 2:1, w/w) afforded biodiesel in a yield of 92.50% and with specifications close to those prescribed by international standards. This catalyst could be reused for up to five cycles without a marked activity loss, with the biodiesel yield in the fifth cycle equaling 80.0%. The developed nanocomposite holds great promise for cutting the costs of biodiesel production, as it is derived from biodegradable raw materials and is renewable, non-corrosive, easy to handle, and green. In addition, the large-scale discharge of this catalyst after use does not pose a hazard to the environment.

A novel magnetic solid base catalyst consisting of an MgFe 2 O 4 -MgO nanocomposite was successfully prepared by synthesizing magnesium ferrite (MgFe 2 O 4 ) as the catalyst support, and it was employed in an esterification reaction for the production of biodiesel. MgFe 2 O 4 was synthesized by a ball-milling mechanochemical method at various furnace temperatures (350°C, 550°C and 750°C), and the best results were obtained at 750°C. The results of TEM revealed an average size of 39 nm. A nanocomposite of MgFe 2 O 4 -MgO was successfully synthesized in this study, as confirmed by Fourier transform infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy-energy dispersive x-ray (SEM-EDX) and transmission electron microscopy (TEM) characterization. The results of the FTIR characterization revealed peaks with wavenumbers corresponding to Mg-O and Fe-O bonds in the range of 500-900 cm -1 , SEM mapping showed that MgO was distributed on the surface of the MgFe 2 O 4 catalyst support, and the MgFe 2 O 4 -MgO average size was found to be 50 nm by TEM. The influence of MgO on MgFe 2 O 4 was determined by varying the molar ratio of MgFe 2 O 4 to MgO from 1: 1, 1: 2 and 1: 3 and by studying the catalytic activity in the esterification of oleic acid to biodiesel. The best MgFe 2 O 4 -MgO nanocomposite have a molar ratio of 1: 2 and gave a percent conversion of 96.089%. Impregnating MgFe 2 O 4 with MgO increased the number of basic active sites, thereby increasing the catalytic activity. This type of nanocomposite is a promising new material for future catalysts.

“…In a study conducted in year 2011, it was found that coconut oil can be a potential feedstock for biodiesel production [63,64]. With the aid of cellulose-Zn/SiO 2 nanocomposite, it was noted that the formation of biodiesel methyl esters can be formed more efficiently, further promising a future application of coconut oil in the fuel industry [65]. Catalysis activity may also be achieved with calcined marlstones to increase the biodiesel yield as well [66].…”

Virgin coconut oil is a useful substance in our daily life. It contains a high percentage of lauric acid which has many health benefits. The current industry has developed several methods to extract the oil out from the coconut fruit. This review paper aims to highlight several common extraction processes used in modern industries that includes cold extraction, hot extraction, low-pressure extraction, chilling, freezing and thawing method, fermentation, centrifugation, enzymatic extraction and supercritical fluid carbon dioxide. Different extraction methods will produce coconut oil with different yields and purities of lauric acid, thus having different uses and applications. Challenges that are faced by the industries in extracting the coconut oil using different methods of extraction are important to be explored so that advancement in the oil extraction technology can be done for efficient downstream processing. This study is vital as it provides insights that could enhance the production of coconut oil.
