Hybrid nanocarbons encapsulating redox and

magnetically active nanoswitches

Maria del Carmen Gimenez Lopez

University of Nottingham, United Kingdom

The electrical coupling of nanocarbons with redox and

magnetically active nanoscale objects has attracted a great deal

of attention for achieving functional hybrid nanostructures

with a wide range of exploitable properties. This is especially

important for designing next-generation electronic or

spintronic devices that will be based on nanoscale functional

materials such as isolated spin centres or single-molecule

magnets. In order to harness the magnetic bistability,

quantum tunnelling of magnetization, and quantum

coherence of nanometer-sized magnetic objects, the coupling

to the macroscopic world that is essential for read and

write purposes has become a key challenge. Hollow carbon

nanostructures with one macroscopic and two nanoscopic

dimensions can act as bridges to achieve this coupling, through

the encapsulation and confinement of magnetic species,

while maintaining their structural integrity and properties

that would otherwise induce decoherence (–a major obstacle

for quantum applications). Another important challenge

facing the humankind today is the production of clean and

sustainable energy where electrochemical technologies

have shown to play an important role. However, the market

potential of electrochemical devices based on electrocatalyst

containing precious metals, such as Pt, is currently hindered

by their short-term durability. As these precious elements

are rapidly diminishing, the research community is forced to

urgently address this major issue until more abundant efficient

electrocatalysts are put forward. In this respect, high-aspect

ratio carbon nanostructures can provide an excellent mean

for the fabrication of highly durable electrocatalyst materials

through platinum encapsulation, allowing their sustainable

use in fuel cells technology.
