Catalytic Applications of Metal Nanoparticles

Metal nanoparticles offer uniquely high surface‐to‐volume ratios and tunable electronic structures, enabling unprecedented catalytic performance in a wide array of chemical transformations. At dimensions below 100 nm, noble and transition-metal nanoparticles exhibit enhanced active‐site densities and altered adsorption energies, lowering activation barriers in processes such as hydrogenation, oxidation and carbon–carbon coupling. Precise control over size, shape and composition allows fine-tuning of activity, selectivity and stability. Bimetallic architectures and core–shell structures introduce synergistic electronic effects, optimising reaction pathways and suppressing deactivation. Choice of support—from oxides to carbon-based materials—further modulates nanoparticle dispersion and metal–support interactions, facilitating catalyst recovery and recyclability. Collectively, these advances have propelled metal nanoparticle catalysts from laboratory curiosities to practical platforms for sustainable chemical production, environmental remediation and energy conversion.

Technical terms

Heterogeneous catalysis: Catalysis in which the catalyst and reactants exist in different phases, typically solid and gas or liquid.

Turnover frequency (TOF): Number of reactant molecules converted per active site per unit time, indicating catalytic activity.

Bimetallic catalyst: Nanoparticle composed of two different metals, whose atomic interactions can enhance reactivity or selectivity.

Support: Solid material, such as oxide or carbon, that disperses nanoparticles and influences their electronic and structural properties.
