application of heteropolyacids in nanoscience for the development of green catalytic reactions

In recent years, green catalysis has become an emerging field of science due to its high activity, selectivity and productivity. Heteropolyacids are promising candidates for green catalysts, as they are harmless to the environment with respect to corrosiveness, safety, quantity of waste, and separability. Other key green aspects of solid heteropolyacids are related to their synthesis in an aqueous process and achievements of successful practical applications. These features have resulted in the development of numerous catalytic protocols for the synthesis of nanostructure materials using heteropolyacids. Therefore, the field of catalysis using heteropolyacids and their applications in nanoscience and nanotechnology continues to attract significant attention, so the number of publications and patents continues to grow, and new researchers are entering the field. Encouraged by our recent success in work with heteropolyacids as green catalysts in field of nanoscience and nanotechnology, the present work mainlyfocused on our fundamental investigations on many of the recent catalytic developments in nanoscience using heteropolyacids.This research demonstrates our important findings for the important catalytic role of heteropolyacids in the advances of nanotechnology, especially in synthesis of nanomaterials, nanocomposites, and nanotubes.
