Bonding in Metals

Bonding in Metals

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

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...

Preparation of Epoxides

Preparation of Epoxides

Overview
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy...

Properties of Organometallic Compounds

Properties of Organometallic Compounds

Organometallic compounds are compounds that contain a carbon–metal bond. Carbon belongs to an organyl group like alkyl, aryl, allyl, or benzyl groups. The metal can be from Group I or Group II of the periodic table, a transition metal, or a semimetal.

Background:

Infinite metal-oxo metal-organic frameworks (MOFs) show promise as catalysts.
Current synthesis methods require harsh conditions and yield small crystals, hindering characterization and performance.

Purpose of the Study:

To develop a mild synthetic protocol for engineering large single-crystal infinite metal-oxo MOFs.
To investigate the catalytic performance of these engineered MOFs.

Main Methods:

A solvothermal protocol using acetic acid was employed to synthesize 1D infinite metal-oxo MOFs (e.g., Zr, Hf, Ce).
Crystallographic structures of large single crystals were identified.
Catalytic upgrading of natural feedstocks was performed using a 1D Zr-BTB-derived catalyst.

Main Results:

The acetic acid protocol successfully produced large single-crystal 1D infinite metal-oxo MOFs with well-defined structures.
The 1D Zr-BTB-derived catalyst achieved a high turnover frequency (1199.1 h⁻¹) and selectivity (99.0%) in fuel production.
Compared to conventional counterparts, the engineered MOF demonstrated significantly enhanced catalytic activity and stability.

Conclusions:

The acetic acid-based solvothermal method is effective for synthesizing high-quality infinite metal-oxo MOFs.
Engineered 1D infinite metal-oxo MOFs offer superior catalytic performance for energy-critical transformations.
This approach facilitates the rational design of industry-oriented heterogeneous catalysts.
