The supported ionic liquids have shown immense potential for numerous applications
in catalysis and separation science. In the present review, the remarkable contribution
of supported ionic liquids has been highlighted. The main emphasis has been laid on
describing the facile separation of gas from binary gas mixtures owing to the capability of
selective transport of permeable gases across supported membranes and removal of environmentally
hazard sulfur compounds from fuels. The catalytic action of supported ionic
liquids has been discussed in other applications such as biodiesel (biofuel) synthesis by
transesterification/esterification processes, waste CO2 fixation into advantageous cyclic
carbonates, and various chemical transformations in organic green synthesis. This review
enclosed a maximum of the published data of the last ten years and also recently accomplished
work concerning applications in various research areas like separation sciences, chemical transformations
in organic green synthesis, biofuel synthesis, waste CO2 fixation, and purification of fuels by desulfurization.
Keywords: Supported ionic liquids, biodiesel, CO2 fixation, desulfurization, organic synthesis, separation science.
