Description |
Nano-materials are important in many diverse areas including energy and environment. They have also emerged as sustainable alternatives to conventional heterogeneous catalysts. We have recently reported the synthesis of a new class of fibrous nano-silica (KCC-1) based materials.1 Such a fibrous morphology observed in these nanospheres has not been seen before in silica materials. The material exhibits excellent physical properties, including a high surface area, a good thermal, hydrothermal, and mechanical stability. KCC-1 was successfully used for various important catalytic reactions such as hydro-metathesis, hydrogenolysis, solid base catalyzed reactions, C-C coupling reactions and also in CO2 capture, with extraordinary activity and stability.2-6 In this talk, I will present synthesis and applications of this fibrous nano-silica (KCC-1).
