Dimensions Controllable Synthesis Of Silver Nano-Morphologies Via Moderate One Step Methodology

The common polyol techniques were used for the synthesis of solo metallic morphology. Here we reported the single-step polyol-solvothermal strategy for the synthesis of zero, one, two, and threedimension silver structure by simply switching the reaction pressure with the help of silver amount and halide ions. Silver seeds in the presence of Cl-ion, at 74.1 mmHg grow in [111] and at 97.4 mmHg grow in [110] direction for the formation of 0D-Ag and 1D-Ag respectively, by protecting (100) facet. Extra halide (Br-) presence at 93.2 mmHg imposes the seeds to grow [110], [100] direction for 2D-Ag, while at 97.4 mmHg grow only in [100] direction for 3D-Ag, due to etching and formation of single crystal seeds. This closed reaction system doesn't need any kind of oxygen scavengers, inert gases, nor need to tune injection speed and stirring speed. This switching strategy can be implemented for the synthesis of other metallic morphologies. (c) 2021 The Society of Powder Technology Japan.
