Layered double hydroxides (LDHs) have been known for many decades as catalyst and ceramic precursors, traps for anionic pollutants, catalysts and additives for polymers, but their successful synthesis on the nanometer scale a few years ago opened up a whole new field for their application in nanom...
Recently, the chemical reduction of nitrates using catalysts has been gaining increased interest due to the disadvantages of conventional nitrate removal technologies. The novel size-dependent physicochemical properties of metallic iron nanoparticles make it of great potential for denitrification.This paper ...
Many catalysts that have been used suffer disadvantages such as high catalytic loading, inability to recycle, and high cost [14]. Recently, catalysts such as nickel, cobalt, cadmium, cerium and copper comprising nanoparticles with NaBH4 are under development and have been widely used [2,[15], ...
the synthesis of nanoparticles by physical and chemical methods has several disadvantages, such as the fact that it is difficult to control the size of the particles within the nanoscale limit, the high energy requirements, the high cost of fabrication, and most importantly, the release of toxic...
To date, IrO2 and RuO2 have been considered to be the most efficient commercial OER catalysts. However, disadvantages such as high price, scarcity, and poor durability have severely hindered their large-scale commercial applications [7,8]. Thus, it is highly desirable to discover and develop ...

These particles and materials have unique optical, magnetic, electronic and chemical properties and have been used in various applications (e.g., solar cells, photovoltaic devices, heterogeneous catalysts, medicine)7,8,9,10. For examples, in chemical catalysis the catalytic activity of the NPs ...
However, the homogeneous Fenton process presents some disadvantages associated to the recuperation and reuse of catalysts, catalyst deactivation due to Fe3+ precipitation or a great dependence on pH [13], [14]. Moreover, this process needs an additional step in the water treatment process, ...
