A transforming society towards sustainable industrial practices and products chooses to
implement “Green Nanomaterial”, with high energy efficiency, minimizing the damage to the environment
and exploitation of non-renewable energy resources. A combined overview of recent developments
in green nanostructured fuel cells with enhanced durability and activity is presented in this
review along with the advancements of green nano materials in the area of corrosion inhibition.
Fuel cells being the next generation ecofriendly energy source, the modification to the solid oxide,
microbial and alkaline fuel cell through green nanomaterial are discussed with an emphasis on electrodes,
electrolyte, electrode catalysts and membrane components. In addition, the role of green nanomaterial
in the form of nano metal oxides, hydroxides, grains, dendrimers, gels, composites, functionalized
graphene, halloysite nanotubes and ionic liquids in greening the phenomenon of corrosion
inhibition, investigated by various researchers is briefly addressed.
As no single engineered green nanomaterial is emerging as unparalleled and most viable, they are
evaluated according to their economic impact, diverse properties, durability and stability. Eventually,
these materials with improvement in biocompatibility, solubility, fabrication and handling techniques
are predicted to change the environmental and occupational scenario, with some of them already
have been found to impact upon the altering global energy needs.
