Biodiesel produced from vegetable oil has recently increased in popularity. However, these edible feedstocks (which are the apparent choice of triglycerides) will not be sufficiently sustainable, given the increasing demand for energy and food, and guaranteed inedible feedstocks are needed. Biodiesel can be generated from these alternative feedstocks using various catalysts. Current studies show that nanocatalysts are extensively used for this purpose and are more preferred than usual homogeneous and heterogeneous catalysts. These nanocatalysts exhibit many advantageous features, including efficient separation steps for both products and catalysts, elimination of the quenching process, high catalytic activity, and large surface area, and provide the possibility for reusability. According to recent reports, the use of nonedible oils and nanocatalysts, such as titanium-doped zinc oxide, magnesium oxide-doped magnesium aluminate, zirconium oxide and many others, are potent with an approximately 80–98 wt% yield of biodiesel under optimized conditions, suggesting that this approach is a suitable option for biodiesel synthesis. This review aims to explore the potency of nonedible feedstocks and nanocatalysts for fatty acid methyl ester synthesis. The findings of the most recent published studies are critically summarized. The catalytic reaction mechanism for biodiesel production is highlighted, focusing on the nanocatalysts. Some nonedible seeds have been reported, and their potency for biodiesel production has been assessed in detail.

纳米催化剂催化的非食用原料生产生物柴油:综述

由植物油生产的生物柴油最近越来越受欢迎。然而,鉴于对能源和食品的需求不断增加,这些可食用原料(它们显然是甘油三酯的选择)将不够可持续,并且需要有保证的不可食用原料。可以使用各种催化剂从这些替代原料中生产生物柴油。目前的研究表明,纳米催化剂广泛用于此目的,并且比通常的均相和非均相催化剂更优选。这些纳米催化剂表现出许多有利的特点,包括产品和催化剂的高效分离步骤、消除淬火过程、高催化活性和大表面积,并提供了可重复使用的可能性。根据最近的报道,使用非食用油和纳米催化剂,例如掺杂钛的氧化锌、掺杂氧化镁的铝酸镁、氧化锆等,在优化条件下具有大约 80-98 wt% 的生物柴油产率,表明这种方法是生物柴油合成的合适选择。本综述旨在探索非食用原料和纳米催化剂在脂肪酸甲酯合成中的效力。对最近发表的研究结果进行了批判性总结。重点介绍了生物柴油生产的催化反应机理,重点关注纳米催化剂。已经报道了一些不可食用的种子,并详细评估了它们生产生物柴油的效力。在优化条件下,生物柴油的产率约为 80-98 wt%,表明这种方法是生物柴油合成的合适选择。本综述旨在探索非食用原料和纳米催化剂在脂肪酸甲酯合成中的效力。对最近发表的研究结果进行了批判性总结。重点介绍了生物柴油生产的催化反应机理,重点关注纳米催化剂。已经报道了一些不可食用的种子,并详细评估了它们生产生物柴油的效力。在优化条件下,生物柴油的产率约为 80-98 wt%,表明这种方法是生物柴油合成的合适选择。本综述旨在探索非食用原料和纳米催化剂在脂肪酸甲酯合成中的效力。对最近发表的研究结果进行了批判性总结。重点介绍了生物柴油生产的催化反应机理,重点关注纳米催化剂。已经报道了一些不可食用的种子,并详细评估了它们生产生物柴油的效力。对最近发表的研究结果进行了批判性总结。重点介绍了生物柴油生产的催化反应机理,重点关注纳米催化剂。已经报道了一些不可食用的种子,并详细评估了它们生产生物柴油的效力。对最近发表的研究结果进行了批判性总结。重点介绍了生物柴油生产的催化反应机理,重点关注纳米催化剂。已经报道了一些不可食用的种子,并详细评估了它们生产生物柴油的效力。
