Constructing Carbon Nanotube/Pt Nanoparticle Hybrids Using an Imidazolium-Salt-Based Ionic Liquid as a Linker

Carbon nanotube (CNT)/Pt nanoparticle (NP) hybrids are synthesized at room temperature using an imidazolium‐salt‐based ionic liquid (IS‐ILs) as a linker. The new three‐component CNT/IS‐ILs/metal heterostructure has uniformly distributed Pt NPs, which form a conducting network on the CNTs that leads...

Description
Summary:Carbon nanotube (CNT)/Pt nanoparticle (NP) hybrids are synthesized at room temperature using an imidazolium‐salt‐based ionic liquid (IS‐ILs) as a linker. The new three‐component CNT/IS‐ILs/metal heterostructure has uniformly distributed Pt NPs, which form a conducting network on the CNTs that leads to high electrocatalytic activity. The hybrid is shown to exhibit higher electrocatalytic activity towards methanol oxidation reactions than a commercial hybrid catalyst and a hybrid containing polymeric linkers.
