The water tolerant heterogeneous acid catalyst (ICaT-2) has been disclosed herein. The catalyst of the invention comprises of rare earth metals in the form of trifluromethansulphonate anchored with hexagonal organic- inorganic functionalized mesoporous silica as base metal through organic-inorganic linkages. The said catalyst composition has the specific surface area in the range of 200 m2/g to 850 m2/g and the pore diameter in the range of 20-50 ?. The ICaT-2 catalyst was found to be highly active and reusable for biomass based chemicals.
