AI Overview
Rhodium (Rh) nanomaterials are highly efficient, durable catalysts used in energy conversion, environmental remediation, and chemical synthesis. They are engineered in various structures—including 0D, 1D, 2D, and porous forms—to maximize surface area and catalytic performance in applications like water electrolysis, hydrogenation, and catalytic converters.
Key Aspects of Rhodium Nanomaterials:
- Catalytic Applications: Rhodium nanoparticles are essential for hydrogenation of biomass derivatives, methanol oxidation, and reducing nitrogen oxides in automobile exhaust. They are particularly effective in catalytic converters, where they can be 3–4 times more efficient than conventional materials.
- Synthesis Methods: Techniques include a modified polyol reduction method, chemical reduction on a soft template to produce mesoporous structures, and using carbon dots as reducing/stabilizing agents.
- Structural Control: Researchers control the size and shape (e.g., nanocubes, nanoshells, nanoframes) to tune surface properties and improve catalytic activity, such as in this inverse-directional galvanic replacement reaction.
- Emerging Uses: Beyond catalysis, Rh-based nanostructures are being investigated for photothermal therapy in cancer treatment.
- Support Materials: Rhodium is often supported on other materials for increased stability, such as carbon nanotubes or titania (TiO2) nanotubes.
Examples of High-Performance Rh Nanostructures:
- Mesoporous Rh Nanoparticles: Offer high surface area and superior performance for methanol oxidation and NO remediation.
- 2D Rh Nanomaterials: Highly efficient for hydrogen evolution and oxygen evolution reactions.
- Rh/Carbon Dot Nanoparticles: Small size (approx. 2.8 nm) with high activity for hydrogenation reactions.

Impact of Rhodium on human health
Most people do not come into contact with rhodium, which is highly toxic and carcinogenic. Rhodium compounds "stain" the skin very strongly. The body can absorb rhodium through inhalation. The health effects of exposure to rhodium have not been thoroughly investigated.

Is rhodium the rarest metal on Earth?
Yet rhodium is arguably the rarest and most volatile precious metal traded on modern markets. Its scarcity is extraordinary. Annual production is tiny compared to other precious metals, and most of it emerges as a by-product of platinum and nickel mining rather than from dedicated rhodium mines.Mar 4, 2026
