The practical application of platinum oxide:

1、 Catalyst

Platinum oxide has high catalytic activity and is widely used in catalyst preparation in fields such as chemical, petroleum, and environmental protection. For example, in the petroleum processing process, platinum oxide can serve as a cracking catalyst to increase the added value of petroleum products; In the field of organic synthesis, platinum oxide can be used as an asymmetric catalyst to improve the selectivity of compounds; In the field of environmental protection, platinum oxide can be used as a catalyst for tail gas treatment to reduce toxic substance emissions. In addition, platinum oxide can also be used to prepare various nanomaterials with catalytic activity.

2、 Fuel cell

Platinum oxide plays a key role in the field of fuel cells and is mainly used as a catalyst for Proton-exchange membrane fuel cell (PEMFC). In fuel cells, platinum oxide catalysts can effectively promote the reaction between hydrogen and oxygen, thereby achieving efficient and environmentally friendly energy conversion. Due to its excellent corrosion resistance, platinum oxide can effectively improve the lifespan and stability of fuel cells. However, due to the high price of platinum oxide, researchers are striving to find more cost-effective alternative materials.

3、 The pharmaceutical industry

Platinum oxide has a wide range of applications in the pharmaceutical industry, especially in the development of anticancer drugs. Platinum oxide can be used as an important synthetic raw material for the preparation of platinum based anticancer drugs such as cisplatin and carboplatin. These platinum drugs destroy the Genetic material of cancer cells by combining with DNA, thus inhibiting the growth and proliferation of cancer cells. In addition, platinum oxide also has certain antibacterial and anti-inflammatory effects, and can be used as a potential active ingredient in drug formulations.

4、 Sensors

Platinum oxide has a wide range of applications in the field of sensors, especially in the research of gas sensors and biosensors. Due to its high surface activity, platinum oxide can effectively capture gas molecules and biomolecules, thereby achieving highly sensitive detection of target substances. For example, in gas sensors, platinum oxide can be used as a sensitive material for toxic gases such as oxygen and carbon monoxide; In biosensors, platinum oxide can be used as a capture and detection material for biological molecules such as proteins and nucleic acids. In addition, platinum oxide can also be used to prepare nanoscale sensors for rapid and accurate detection of target substances.

5、 Other applications

In addition to the above application fields, platinum oxide has some other uses. For example, in the electronics industry, platinum oxide can be used as an additive for Electroceramics to improve their conductivity; In the ceramic industry, platinum oxide can be used as a ceramic colorant to give ceramics a beautiful metallic luster; In the field of photocatalysis, platinum oxide can be used as a photocatalyst to achieve efficient degradation of organic pollutants.

Platinum oxide, as a multifunctional precious metal oxide, has important applications in various fields. With the development of technology and the expansion of application fields, the research on platinum oxide will be more in-depth, and its applications in catalysts, fuel cells, pharmaceutical industries, sensors, and other fields will also receive more widespread attention. However, the high price and Scarcity of resources have brought some restrictions to the popularization of platinum oxide application. Therefore, developing more cost-effective alternative materials and improving the recovery and utilization rate of platinum oxide will become important directions for future research.
