This book introduces recent progress in preparation and application of
core-shell and yolk-shell structures for attractive design of catalyst
materials. Core-shell nanostructures with active core particles covered
directly with an inert shell can perform as highly active and selective
catalysts with long lifetimes. Yolk-shell nanostructures consisting of
catalytically active core particles encapsulated by hollow materials are
an emerging class of nanomaterials. The enclosed void space is expected
to be useful for encapsulation and compartmentation of guest molecules,
and the outer shell acts as a physical barrier to protect the guest
molecules from the surrounding environment. Furthermore, the tunability
and functionality in the core and the shell regions can offer new
catalytic properties, rendering them attractive platform materials for
the design of heterogeneous catalysts. This book describes the recent
development of such unique nanostructures to design effective catalysts
which can lead to new chemical processes. It provides an excellent guide
for design and application of core-shell and yolk-shell structured
catalysts for a wide range of readers working on design of attractive
catalysts, photocatalysts, and electrocatalysts for energy,
environmental, and green chemical processes.
