The solvent or reaction medium is one of the key players to decide the material’s morphology during synthesis. Glycerol is an environmentally benign solvent that have excellent chelating capability and also expected to control the morphology of the final material. Herein, aqueous glycerol is employed as a green solvent to synthesis zinc glycerolate and the corresponding ZnO micro-flower structures with an intention to develop a greener chemical process for inorganic material synthesis. A clear solution of zinc ammonium complex is used as a source of zinc, which converts to zinc glycerolate in the presence of glycerol. Glycerol plays a dual role as a reactant to form zinc glycerolate and as a solvent to control the morphology. The unreacted glycerol is recovered after the reaction and reused further, which make the current process more sustainable and economical. The flower-structured zinc glycerolate and ZnO are then used to modify a glassy carbon electrode to make a binder-free, non-enzymatic amperometric electrochemical sensor for p-nitrophenol that is a brutal environmental pollutant present in water. Excellent sensitivity, selectivity and stability of the modified electrode is found and can be a good alternative for the purpose.
