Nanocatalysts have received much attention because of their vast
applications in various organic pollutants removal as well as their selectivity, ease in
separation, eradicating the expensive materials and hazardous chemicals. Nanocatalysts
are the heart of scientific field because of their vast applications in multidisciplinary
sciences. This chapter provided a brief knowledge using nanocatalyst for the removal
of organic toxins, for instance nitrophenols and dyes, which are at alarming condition.
The readers will be benefited from this chapter and will learn about photocatalysis and
its application. The use of semiconductors is appropriate in photocatalysis, therefore,
much information is available about semiconductor. An important morphological
nanocatalyst is the layered double hydroxide; also worked as a solar catalyst for the
removal of contaminants and various support are present for these material to enhance
its catalytic performance. Supported materials in nanocatalysis are required to stabilize
the nanoparticles (Nps) from being aggregated and also offer any easy route in
separating the catalyst after the reaction. Such criteria are highly demanded at industrial
level.
