Design of multifunctional magnetic hybrid silica aerogels with improved properties

Magnetic aerogel: an advanced material of high importance

“…The low density (240 mg cm À3 ) high magnetic ability (saturation magnetization 54 emu g À1 ) of the resultant silica-based aerogel along with improved mechanical strength (780 kPa), low thermal conductivity (0.055 W m À1 K) and suitable surface area (53 m 2 g À1 ) make them suitable for potential in environmental cleaning as well as drug loading and delivery applications. 53 The effect of different parameters on the magnetic behavior of hydrophobic magnetic aerogels was overviewed by Nagappan and Ha. It was concluded that the calcination temperature, composition, and some other parameters greatly affect the size and magnetic property of the nal aerogel material.…”

Rational design and controllable synthesis of polymer aerogel-based single-atom catalysts with high loading

“…Figure 4 shows the synthesis process of the organic-inorganic composite aerogel, and as shown in Figure 4, before the carbonization process is carried out, one or more kinds of molecular, ions or particles can be directly compounded in aerogels in the case of without affecting the physical properties of aerogels. [105][106][107] In addition, the prepared aerogel can also support the catalyst by immersing solid aerogel in a metal salt solution or vapor deposition and other methods. These methods are generally considered to be the simplest and economical methods to prepare multiple composite catalysts.…”

Synthesis of sodium silicate-based silica aerogels with graphene oxide by ambient pressure drying

“…To improve the mechanical properties of silica aerogels, there are two methods widely used. One of these is addition of polymers to make the highly cross-linked threedimensional nano-network while the second is incorporation of fibres or nano dopants inside the silica aerogel matrix [16][17][18][19][20][21].…”
