“…Saeedi et al [98] prepared zeolite imidazolate framework (ZIF-8) doped with potassium (KNa/ZIF-8) and these catalysts were used in the production of biodiesel from soybean oil as the feedstock via transesterification process. Further, to increase the basicity and to enhance the catalytic performance of ZIF-8 during transesterification with methanol, sodium and potassium were added to it.…”

The excessive consumption of petroleum resources leads to global warming, fast depletion of petroleum reserves, as well as price instability of gasoline. Thus, there is a strong need for alternative renewable fuels to replace petroleum-derived fuels. The striking features of an alternative fuel include the low carbon footprints, renewability and affordability at manageable prices. Biodiesel, made from waste oils, animal fats, vegetal oils, is a totally renewable and non-toxic liquid fuel which has gained significant attraction in the world. Due to technological advancements in catalytic chemistry, biodiesel can be produced from a variety of feedstock employing a variety of catalysts and recovery technologies. Recently, several ground-breaking advancements have been made in nano-catalyst technology which showed the symmetrical correlation with cost competitive biodiesel production. Nanocatalysts have unique properties such as their selective reactivity, high activation energy and controlled rate of reaction, easy recovery and recyclability. Here, we present an overview of various feedstock used for biodiesel production, their composition and characteristics. The major focus of this review is to appraise the characterization of nanocatalysts, their effect on biodiesel production and methodologies of biodiesel production.

“…A relatively trusting study using sodium–zeolite imidazolate framework (ZIF-8) doped with potassium namely KNa/ZIF-8 as a solid basic catalyst for biodiesel production by transesterification of soybean oil was developed (Table , entry 20) . Accordingly, KNa/ZIF-8 with K loading of 0.08% showed the highest amount of medium (0.088 mmol/g, 415–450 °C) and strong basic sites (0.079 mmol/g, 450–490 °C; 0.014 mmol/g, 490–670 °C) together with a high surface area of 1195 m 2 /g and a narrow pore diameter of 1.21 nm.…”

Efficient transformation of renewable biomass into chemicals and biofuels, including liquid biomass-derived nonedible oils to biodiesel, is of great importance. Developing heterogeneously functional materials is being deemed as a subject of particular interest to scientists in selective catalytic chemistry especially for biomass valorization. In this regard, porous polymers, featuring high surface areas, prominent stabilities, and chemically adjustable moieties, have attracted extensive concerns. In this Review, recent developments on the application of heterogeneously functionalized porous polymeric catalysts of high performance, including acid/base chemosynthetic organic polymers/natural biodegradable biopolymers like chitosan, organic–inorganic hybrid polymeric materials such as functional porous coordination polymers, and porous polymers immobilized with enzymes for effective upgrading of oil feedstocks into biodiesel are summarized. Catalytic protocols using functional polymeric catalysts provide significant benefits for realizing biorefinery procedures because of the following reasons: (i) no polluting reagents, (ii) high activities and selectivities, and (iii) simple and convenient catalyst recycling. Attention has been drawn, in particular, to understanding the role of acidity/basicity, hydrophilicity/hydrophobicity, swelling property, and porosity of polymer materials in biodiesel production through transesterification and esterification reactions. In addition, plausible reaction mechanisms are also depicted accordingly, while highlighting the main remaining challenges and future prospects.

“…Saeedi et al [72] prepared KNa/ZIF-8 from Na-zeolite imidazolate framework doped with potassium under hydrothermal conditions and used it for soybean oil transesterification. The experimental findings showed very good catalytic activity and stability of KNa/ZIF-8, owing to the high amount of strong and medium basic sites, the uniformity of the elemental composition, and the high surface area (about 1195 m 2 /g).…”

Zeolite-based catalysts are versatile catalytic systems for a wide range of laboratory studies and industrial scale processes. The chemical composition, ion exchange, and pore size structure attributes of zeolites are responsible for their extensive catalytic applications. Esterification is one of the most important and routinely processes in diverse fields of organic synthesis. It has a long history in both industrial processes and laboratory work due to its versatility. This review intends to give a detailed insight into the significance of zeolite-based catalysts for ester bond formation
