Recent advances in synthesis techniques for metal nanoparticles have led to renewed interest in designing novel catalytic materials.While a great deal of progress has been made by the chemistry community,several drawbacks remain: 1) stabilizing agents that are used to coat and disperse nanoparticles in solution must be removed post-growth to access the surface of the particles,2) scale-up is difficult since the nanoparticles are typically made in batches,3) nanoparticles must be transferred to substrates to implement them in applications,and 4) small particles less than 5 nm in size are challenging because of Ostwald ripening effects.To address these issues,our group has developed techniques for metal nanoparticle synthesis based on a novel class of plasmas termed ‘microplasmas.’
