Detailed explanation-1: -Nanostructure provides emerging immobilization support due to nanoscale size and large surface area. Microbial enzymes such as lipase from Pseudomonas cepacia are immobilized on the surface of nanoparticles and enhance the production of biofuel due to enhanced transesterification reaction (Goh et al.
Detailed explanation-2: -Furthermore, most nanocatalysts have some advantages, as they are chemically stable, cheap, less toxic, readily available, and have excellent photoactive properties at the nanoscale, i.e. shows an interval of 1–100 nm.
Detailed explanation-3: -Some of the important solid nanocatalysts which have been used in biodiesel production are metal oxides (Cao, MgO, Fe3O4, Ca/Al/Fe3O4, KF/Al2O3, SnO2, etc.), sulfated oxides, hydrotalcites, zeolites, zirconia, etc. [64, 65]. Among these, some of nanocatalysts have been briefly discussed below.
Detailed explanation-4: -Photocatalytic Decolorization. Large amounts of textile dye (e.g., malachite green dye, methylene blue, azo dyes, etc.) Production of Biofuel. Hydrogen Energy Carrier. Nanocatalyst in Solid Rocket Propellants. Water Purification. Wastewater Treatment. 17-Nov-2021
