1、 The unique feature of ultrafine platinum powder
Compared with ordinary platinum powder, ultrafine platinum powder has significant differences in particle size, density, and specific surface area. Its average particle size is between 0.4-1.2 μ m, with a loose density of 0.5-1.2 g/cm2, a tap density of 1.0-1.6 g/cm2, a specific surface area of 4-8 m2/g, and a particle shape of spherical or approximately spherical. These characteristics give ultrafine platinum powder significant advantages in electrode slurry.
Taking the average particle size as an example, the particle size of ultrafine platinum powder is even smaller, which makes it
Electrode slurryIt is easier to disperse evenly and can be better coated on the electrode surface. In contrast, ordinary platinum powder may have problems such as coarse particles and poor dispersibility, resulting in low surface quality of the electrode. Ultra fine platinum powder, with its more compact particle shape and larger specific surface area, can provide more active sites and better catalytic performance, thereby significantly improving the efficiency and stability of the electrode.

Ultra low temperature fuel cells have important application prospects in the energy field. However, traditional platinum powder is prone to lose activity at lower temperatures, which limits the low-temperature performance of fuel cells. By using ultrafine platinum powder, this problem can be overcome. According to data, electrode slurries prepared using ultrafine platinum powder exhibit higher catalytic activity and stability under ultra-low temperature conditions, enabling fuel cells to operate continuously and efficiently at low temperatures.

Electrochemical energy storage devices are a core component of modern energy technology. The application of ultrafine platinum powder in energy storage devices is also receiving increasing attention. For example, ultrafine platinum powder can be used to prepare efficient electrochemical catalysts, improve the energy conversion efficiency and cycling stability of electrochemical energy storage devices. Meanwhile, due to its particle shape advantage, ultrafine platinum powder can also help reduce the internal resistance of electrochemical energy storage devices, improve the power density and rapid response performance of energy storage devices.

The unique properties of ultrafine platinum powder have opened up vast opportunities for its application in the field of electronic technology. However, with the continuous advancement of technology, how to further improve the performance and stability of ultrafine platinum powder has become a topic worth exploring.
Firstly, by adjusting the preparation process of ultrafine platinum powder, its particle size and shape can be further precisely controlled. For example, the use of surfactants and other regulators can prepare more uniform ultrafine platinum powder, which can greatly improve the dispersibility and coating performance in the electrode slurry.
Secondly, ultrafine platinum powder can be composite modified with other materials to further improve its catalytic performance and stability. For example, composite modification of ultrafine platinum powder with carbon support can improve its specific surface area and electrical conductivity, thereby enhancing the efficiency and stability of the electrode.
