Abstract
Hollow structures are one of the most highlighted topics of research in
nanotechnology. These hollow structures can be in the form of nanospheres,
nanocages, nanorods, nano boxes, etc. They can be single-layered or multi-layered,
with different kinds of doping. All these variations in hollow structures open up various
fields of research, from biomedicines to optoelectronics. With the discovery of hollow
structures like carbon buckyball, nanotubes, etc., several application-based -research
was carried out, both theoretically as well as experimentally. Modifications are
observed in the properties of a material when formed in a hollow shape like better
conductivity, trapping capacity, catalytic effect, etc. These properties were the
highlight of the studies. This field is still under investigation, and there is a lot of scope
for new possibilities in the future. This chapter covers the basic information about
different kinds of hollow structures like carbon buckyball, variations in their properties,
along with recent developments and their applications. This chapter also includes
detailed research about buckyball structures of ZnO, ZnS, and Al-doped ZnO using
simulations with their comparative study and future applications.
