Microwave-assisted synthesis of mutually embedded Rh concave nanocubes with enhanced electrocatalytic activity†
Abstract
Novel mutually embedded Rh concave nanocubes were synthesized by reducing Rh(acac)3 in tetraethylene glycol in the presence of benzyldimethylhexadecylammonium, KI and polyvinylpyrrolidone under microwave irradiation for 120 s. KI and HDBAC were crucial to the formation of mutually embedded nanostructures. The as-prepared Rh nanocrystals exhibited higher electrocatalytic activity and stability.
