In fact this leads to significant greenhouse gas emissions and the production of non-environmental friendly materials.
The higher cost, non-environmental friendly and complexity in fabrication of conventional catalysts lead to the development of biocathodes where microorganisms themselves act as the catalyst.
The necessity for complete removal of traces of catalyst from the product after catalyst deactivation, to avoid the deterioration of the product, is a further challenge faced in the processes catalysed by non-environmental friendly catalysts [9].
Moreover, it is a non-destructive, environmental friendly, rapid technique capable for on-line application.
Zinc oxide (ZnO) has a large exciton binding energy of 59 meV, wide band gap of 3.37 eV at room temperature, piezoelectricity, catalytic activity, low cost in production, and bio-compatibility and is non-toxic (environmental friendly) and chemically stable [9, 10].
In this study, we designed a new palladium nanocatalyst on chitosan/cellulose composite for the first time to increase the use of sustainable polysaccharides, which are cheap, non-toxic, environmental friendly, abundant in nature, and can be used as support materials for metallic nanoparticles.
Demand of electricity is increasing day by day and fossil fuels are limited for power generation, so there is a need to adopt non-conventional and environmental friendly methods of power generation to meet the country's requirements.
With the advantages of stable, low cost, high energy density, non-inhibitor to enzymes, and environmental friendly, maltodextrin is suggested to be an ideal fuel to power enzymatic fuel cells.
Thus, environmental friendly, cost effective, non hazardous stable nanoparticles were prepared by green synthesis using red algae, G. crassa.
These natural fibers are completely renewable, environmental friendly, high specific strength, non-abrasive, low cost, bio-degradability.
