In the present work, the aim is to synthesize reduced graphene oxide (rGO) and zinc:reduced graphene oxide composite catalysts (ZnO:rGO) for esterification of acetic acid with n-heptanol. The physical and chemical characteristics of the rGO and rGO-metal oxide composite catalysts such as textural surface characteristics, surface morphology, thermal stability, functional groups, and elemental analysis were studied. The surface areas of rGO, ZnO(0.5 M), and ZnO(1 M) were recorded, respectively, at 31.72, 27.65, and 36.19 m2 g–1. Furthermore, esterification reaction parameters such as the reaction time, catalyst dosage, and reaction temperature for acetic acid were optimized to check the feasibility of rGO-metal oxide composites for a better conversion percentage of acetic acid. The optimized catalyst was selected for further optimization, and the optimum reaction parameters found were 0.1 wt % of catalyst, 160 min reaction duration, and 100 °C reaction temperature with a maximal yield of 100%. At 110 °C, the reaction conducted in the presence of 0.1 g of catalyst displayed more yield than the uncatalyzed reaction.

The development of solid acid catalysts, especially based on metal oxides and different magnetic nanoparticles, gained much awareness recently as a result of the development of different nano-based materials. Solid acid catalysts based on metal oxides are promising for the (trans)esterification reactions of different oils and waste materials for biodiesel production. This review gives a brief overview of recent developments in various solid acid catalysts based on different metal oxides, such as zirconia, zinc, titanium, iron, tungsten, and magnetic materials, where the catalysts are optimized for various reaction parameters, such as the amount of catalyst, molar ratio of oil to alcohol, reaction time, and temperature. Furthermore, yields and conversions for biodiesel production are compared. Such metal-oxide-based solid acid catalysts provide more sustainable, green, and easy-separation synthesis routes with high catalytic activity and reusability than traditionally used catalysts.

In the last decades, heterogeneous catalysis has emerged as a promising approach for sustainable synthesis. Among this, metal‐based graphene oxide (GO) as catalysts is widely used due to their unique properties such as physical and thermal stability of the catalysts in successive reaction runs and reusability. Metal‐supported GOs are quite prevalent and probably suitable acidic catalysts for both research laboratories and industrial processes. Herein, we have described the catalytic efficiency of various metal‐supported GO catalysts in different organic transformations like oxidation, reduction, multicomponent reactions, alkylation, condensation, dehydration, dehydrogenation, and Suzuki, Heck, and Sonogashira reactions. This article has been divided into three subsections: (i) GO‐supported metal as a catalyst, (ii) GO‐supported bimetal as a catalyst, and (iii) GO‐supported metal oxide as a catalyst for the easier understanding of the vast community of researchers. The foremost aim of this article is to summarize the uses of metal‐supported GO in the preparation of diverse synthetic molecules. The recent advancements in GO metal composites as catalysts with their applications have been deliberated.
