Biomolecule-assisted solvothermal synthesis of coral-like Bi 2S3 nanostructures

Bi2S3 nanostructures were prepared via a simple biomolecule-assisted solvothermal synthesis through the reaction between bismuth nitrate and l-cysteine, using ethylenediamine as a solvent because of its strong polarity and coordination. The ethylenediamine solvent also acted as a structure-directing...
