Abstract:

Herein, we report the synthesis and characterization of graphene oxide (GO) impregnated into a Zr-based metal-organic framework (MOF-801), denoted as MOF-801@GO, as a catalyst for esterification reactions. The synthesized catalyst was thoroughly characterized using various techniques, including Fourier-transform infrared (FTIR) spectroscopy, Brunauer-Emmett-Teller (BET) surface area measurements, and scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and inductively coupled plasma (ICP) spectroscopy. The surface acid strength was evaluated by ammonia temperature-programmed desorption (NH₃-TPD). The catalytic performance of MOF-801@GO was assessed in the esterification of carboxylic acids with alcohols using no solvent. Under optimized reaction conditions, the catalyst achieved a high esterification yield of up to 95%. Notably, the catalyst was readily recovered and reused over multiple cycles with minimal loss of catalytic activity or structural integrity, highlighting its promise for practical esterification applications.

Oxidation–Reduction Reactions

Oxidation Numbers

Oxidation Numbers

In redox reactions, the transfer of electrons occurs between reacting species. Electron transfer is described by a hypothetical number called the oxidation number (or oxidation state). It represents the effective charge of an atom or element, which is assigned using a set of rules.

Alkali Metals

Alkali Metals

Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

Oxidation and Reduction of Organic Molecules

Oxidation and Reduction of Organic Molecules

Energy production within a cell involves many coordinated chemical pathways. Most of these pathways are combinations of oxidation and reduction reactions, which occur at the same time. An oxidation reaction strips an electron from an atom in a compound, and the addition of this electron to another compound is a reduction reaction. Because oxidation and reduction usually occur together, these pairs of reactions are called redox reactions.
The removal of an electron from a molecule, results in a...

Phase I Oxidative Reactions: Overview

Phase I Oxidative Reactions: Overview

Phase I biotransformation, or functionalization, is a crucial chemical process that converts drugs and other xenobiotics into more water-soluble forms, facilitating expulsion from the body. It involves oxidative, reductive, and hydrolytic reactions that add or unveil polar functional groups on lipophilic substrates. Key players in phase I reactions are the mixed-function oxidases. Situated in liver cell microsomes, these enzymes predominantly carry out drug metabolism. They require molecular...

Metal-Ligand Bonds

Metal-Ligand Bonds

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
