However, the common NPs are usually composed of precious metal gold (Au) or silver (Ag). As for this aspect, exploring more efficient nanoparticles (NPs) for direct absorption solar collectors (DASCs) has become a key issue in solar collector applications. The development of high-efficiency, low-cost and pollution-free new energy has become the focus of scientific research in the 21st century. Theĭevelopment of metal/metal oxide core-shell nanoparticles has become popular nowadays due to their widespread use inĬatalysis and other environmental remedial applications. Overview of the present methods involved in synthesis and tunable factors responsible for their end applications. Interaction, depending upon the selection of material used, which highly influences the end application. These nanostructures can have a number of combinations in close Lowering the consumption of precious materials, and so on. Implementing surface modification, increases functionality, stability and dispersibility, control on the release of the core, The introduction of a different crust layer over the core particle has many reasons, such as it helps in Properties of Core/shell nanoparticles are highly modified from that of their simple pure nanomaterials, thus they usually called The core/shell nanoparticles have some distinct features that is responsible for their importance. Each of this structural classification has its own importance, method of Types of core/shell particles can have a large variety. When classified on the basis of structure, the Popularity in the recent times due to their interesting properties and applications. A special category of materials at nanoscale level has gained The large value of this ratio increases the dominance of the surfaceĪtoms of the nanoparticles in relation to those in its interior. Particles, these have increased surface area to volume ratio. When we consider matter at nanoscale, one of the most important aspects to be considered is that due to the small size of the
