Rhodium (Rh) is a rare platinum group metal that is widely used in industry for its high corrosion resistance and excellent properties in a variety of catalytic processes. Rhodium hydroxide, as an important compound of rhodium, although its stability and reactivity are not as good as other rhodium compounds, such as rhodium chloride or rhodium acetate, it still has unique applications in specific chemical synthesis and materials science fields. This paper will discuss the preparation of rhodium hydroxide and its potential application in industrial and scientific research.
