One pot green synthesis of Ag, Au and Au-Ag alloy nanoparticles using isonicotinic acid hydrazide and starch

- Green synthesis of Ag, Au and their alloy NPs using starch as a capping agent and water as the solvent.
- Synthesis of Ag, Au and their alloy NPs using isoniazid (INH) as a reducing agent.
- The redox behavior of alloy NPs depends on their size as well as their composition.
- The catalytic reduction of 4-nitrophenol and picric acid by metal and alloy NPs.
- When the size increases alloy NPs show bathochromic shift in their emission.
