Introduction

Copper(II) oxide, a black powdery or crystalline compound, plays a critical role in numerous industrial applications due to its unique properties such as high thermal and electrical conductivity, and catalytic properties. Its chemical formula is CuO, with a molecular weight of 79.545 g/mol. This compound is also known as cupric oxide and is utilized in various sectors ranging from electronics to ceramics.

Industrial Applications of Copper(II) Oxide

Catalysis

Copper(II) oxide is extensively used as a catalyst, particularly in redox reactions and organic synthesis processes. It serves as an active site in the catalytic conversion of carbon monoxide to carbon dioxide in automotive exhaust systems. Furthermore, it is vital in the synthesis of various organic compounds. The effectiveness of CuO catalysts is quantified by turnover frequency (TOF), which can range from 1 to 100 h^-1, depending on the specific reaction mechanics and conditions.

Ceramics and Glass

In the ceramics industry, copper(II) oxide acts as a coloring agent, imparting a distinct blue-green color to glass and ceramics. It is used in concentrations ranging from 0.1% to 2% by weight, depending on the desired intensity of the color. Additionally, CuO enhances the durability and mechanical properties of ceramic products.

Electronics

In electronics, copper(II) oxide functions as a semiconductor material with a bandgap of approximately 1.2 to 1.5 eV. It is used in the fabrication of thin-film solar cells and gas sensors. Its conductive properties are leveraged in the development of superconductors and as a component in conductive pastes for photovoltaic cells.

Battery Manufacturing

Copper(II) oxide is an essential component in lithium-ion batteries. It serves as an anode material due to its high capacity and cycling stability, with specific capacities typically reaching 600-700 mAh/g. The efficiency and longevity of CuO-based batteries are subjects of ongoing research, aimed at optimizing charge-discharge cycles and minimizing degradation.

Antifouling and Antimicrobial Coatings

Due to its antifungal and antibacterial properties, CuO is incorporated into coatings for marine vessels to prevent biofouling, as well as in surfaces requiring antimicrobial features. Studies show that copper-based coatings can reduce bacterial presence by up to 99.9% within a 24-hour contact period under controlled conditions.
