Novel mutually embedded Rh concave nanocubes were synthesized by reducing Rh(acac) 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.
通过在苄基二甲基十六烷基铵、碘化钾和聚乙烯吡咯烷酮存在下，于微波辐射120秒的条件下，在四甘醇中还原Rh(acac)，合成了新型相互嵌入的Rh凹面纳米立方体。碘化钾和十六烷基苄基二甲基氯化铵对相互嵌入纳米结构的形成至关重要。所制备的Rh纳米晶体表现出更高的电催化活性和稳定性。
