Viable methodologies for the synthesis of high-quality nanostructures.

The development of environmentally benign methods for the synthesis of nanomaterials has become increasingly relevant as chemists look to shape a more sustainable future. In this critical review, we present current work towards developing alternative methods for synthesizing a wide range of high-quality nanomaterials with predictable and controllable size, shape, composition, morphology and crystallinity. In particular, we focus on the inherent advantages of utilizing porous membrane templates, ultrasonic and microwave irradiation, alternative solvent systems, as well as biologically-inspired reagents as reasonably cost-effective, environmentally responsible methods to generate metal, metal oxide, fluoride, sulfide, selenide and phosphate nanomaterials.
