“…The increased catalytic activity is because of high crystallinity and increased acidity. From the given study it can be concluded that functionalization of zeolites with the nanocatalyst will provide a new insight in increasing the production of biodiesel on large scale (Mohebbi et al, 2020).…”

Necessity and exploitation of fossil fuel products are implacable in serving the needs of humanity despite being a finite and limited resource. To meet the thrust of energy, biofuels derived from varieties of renewable resources are imperative in fulfilling the demand of renewable fuels on a large scale without creating environmental concerns. Biofuels are inevitably the result of the carbon fixation process which stores chemical energy, ultimately reducing the total amount of carbon dioxide. Different kinds of biofuels like bioethanol, biomethanol, biogas, and biodiesel are derived depending on varieties of feedstock materials. Among these, production of biodiesel augments the progression of clean and renewable fuel. In this review, we have discussed the production of biodiesel derived from various feedstock and using several processes like pyrolysis, direct blending, micro-emulsion, and trans-esterification, with critical discussion focussing on increasing biodiesel production using nanocatalysts. Biodiesel production mainly proceeds through homogenous and heterogeneous catalysis via trans-esterification method. The review further discusses the significance of nanocatalyst in heterogeneous catalysis based trans-esterification for large scale biodiesel production. With the advent of nanotechnology, designing and modification of nanocatalyst gives rise to attractive properties such as increased surface area, high thermal stability, and enhanced catalytic activity. The role of nanocatalysts have been extensively studied and investigated in regard to the increased biodiesel production. Along with the modification of nanocatalysts, we have briefly discussed the physico-chemical properties and the role of the optimization parameters as it plays a pivotal role in enhancing the biodiesel production commercially.

“…The acidic property of zeolites is due to imbalance in charge present on alumina and silica units, which mainly contribute to the aluminosilicates framework. Overall the uniform pore size and acidity are a considerably important parameter in enhancing the biodiesel (Fattahi et al, 2019;Mohebbi et al, 2020).…”

“…Another solution would be substituting biofuel and biodiesel for fossil fuels [13][14][15]. Within recent years, the usage of biofuels in transport industry has been heeded based on environmental considerations [16][17][18][19][20][21][22][23]. The amounts of carbon dioxide, sulfur dioxides, and aromatics are lower in the combustion of biodiesel in comparison with petrodiesel.…”

The transesterification process with potassium hydroxide (KOH) catalyst and the methanol supercritical process were evaluated by Aspen HYSYS software. Castor oil and methanol were used as feed and alcohol. In order to accomplish verification, the simulation results were compared to a laboratory research. For economic analysis, these results were transferred to Aspen Economic Analyzer software. Piping and process equipment cost were calculated for the two processes. Additionally, direct and indirect costs of these processes were estimated.

“…Nevertheless, those sustainable energy sources are subjected to the infrequent time bounded among trade and necessity. As an impact, researchers are focusing towards the technologies which could exhibit exceptionally high energy density, economic, environment-benign and safety such as energy harvesting and storage, metal-air batteries, windmills, hydrogen fuels, solar cells, water electrolysis and fuel cells [2][3][4][5]. Most of those alternative tech-nologies are employing the electrochemical reactions, and efficiency of energy harvesting processes often suffered by the lethargic electron transfer process.…”

“…It is obvious that carbon as a solid support for Pt NPs is of highly attractive due to its high conductivity, high stability, and controllable structure. On the other hand, among the above-mentioned metal oxides, MoO 3 is one of the most important semi conductive oxide has been widely investigated for its superior gas-sensitive and lithium storage properties due to its high chemical stability [2][3][4][5][6]. Therefore, inclusion of MoO 3 in the catalyst design can boost the electronic conductivity of the Pt NPs thereby enhance the catalytic activity.…”

Constructing and making highly active and stable nanostructured Pt-based catalysts with ultralow Pt loading are still electrifying for electrochemical applications such as water electrolysis and fuel cells. In this study, MoO 3 ribbons (RBs) of few micrometer in length is successfully synthesized via hydrothermal synthesis. Subsequently, 3-dimentional (3D)-silicate layer for about 10 to 15 nm is introduced via chemical deposition onto the pre-formed MoO 3 RBs; to setup the platform for Pt metaldots (MDs) deposition. In comparison with the bare MoO 3 RBs, the MoO 3-Si has served as a efficient solidsupport for stabilizing and accommodating the uniform deposition of sub-2 nm Pt MDs. Such a structural design would effectively assist in improving the electronic conductivity of a fabricated MoO 3-Si-Pt catalyst towards MOR; the interfaced, porous and 3D silicate layer has assisted in an efficient mass transport and quenching the poisonous CO a d s species leading to a significant electrocatalytic performance for MOR in alkaline medium. Uniformly decorated, sub-2 nm sized Pt MDs has synergistically oxidized the MeOH in association with the MoO 3-Si solid-support hence, synergistic catalytic activity has been achieved. Present facile approach can be extended for fabricating variety of highly efficient Metal Oxide-Metal Nanocomposite for energy harvesting applications.
