Technical exploration on avoiding agglomeration of nanoscale platinum particles in the preparation process of platinum electrode slurry

With the development of technology, the demand for high-performance electrode materials is increasing day by day. Platinum electrodes play an important role in fields such as fuel cells, sensors, and catalysis due to their excellent conductivity and chemical stability. However, nanoscale platinum particles are prone to agglomeration, which not only affects their active surface area but also reduces the overall performance of the electrode. This article will introduce the research and development of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand YB8201 Platinum Electrode SlurryAnd discuss how to effectively avoid the aggregation of nanoscale platinum particles during the preparation process.

1、 Introduction

Platinum electrode is one of the core components of various modern technologies, especially in the field of energy conversion and storage. It is crucial to develop uniformly dispersed and highly conductive platinum electrode slurries in order to improve the efficiency and lifespan of platinum electrodes. Advanced Institute (Shenzhen) Technology Co., Ltd. is committed to the research and application of new materials, and has launched the YB8201 platinum electrode slurry with high stability and good dispersibility.

2、 Characteristics of YB8201 Platinum Electrode Slurry from Yanbo Brand

1. Excellent dispersibility: Through special synthesis processes and technical treatments, platinum particles are ensured to maintain good dispersion in solvents.
2. Enhanced adhesion: A new type of organic additive is used to improve the bonding strength between platinum particles and the substrate, thereby reducing the chance of direct contact between particles.
3. Optimized particle size distribution: Strict production control makes platinum particle size more uniform, which helps further reduce the possibility of agglomeration.

3、 Methods to avoid aggregation of nanoscale platinum particles

（1） Choose the appropriate solvent

The choice of solvent is crucial for preventing platinum particle aggregation. A solvent that can provide sufficient steric hindrance effect should be selected to prevent particles from approaching each other. At the same time, the solvent also needs to have good volatility to facilitate removal during subsequent processing.

（2） Add surfactants or dispersants

Surfactants or dispersants can adsorb onto the surface of platinum particles, forming a protective film that increases the repulsion between particles and effectively prevents them from aggregating due to van der Waals forces.Advanced Institute (Shenzhen) Technology Co., LtdSpecific surfactants have been introduced into YB8201, achieving better dispersion effects.

（3） Regulating pH value

Appropriate pH adjustment can help maintain the surface charge state of platinum particles, thereby utilizing electrostatic repulsion to suppress particle aggregation. Normally, platinum particles are positively charged under acidic conditions and negatively charged under alkaline conditions. Therefore, adjusting the pH value of the solution according to specific application scenarios can effectively control the interactions between particles.

（4） Mechanical stirring and ultrasonic treatment

Gentle but sufficient mechanical stirring helps to break down the formed small clusters and promote the uniform distribution of platinum particles throughout the system. In addition, ultrasonic treatment is a very effective means, which can generate a local high temperature and high pressure environment through cavitation, separating particles in close contact.

（5） Heat treatment process

Reasonable heat treatment can not only remove excess organic components, but also strengthen the connection between platinum particles and the carrier. However, excessive temperature may cause platinum particles to rearrange or even fuse, so precise control of heating conditions is necessary.
