【 摘 要 】

The significance of silver nanostructures has been growing considerably, thanks to their ubiquitous presence in numerous applications, including but not limited to renewable energy, electronics, biosensors, wastewater treatment, medicine, and clinical equipment. The properties of silver nanostructures, such as size, size distribution, and morphology, are strongly dependent on synthesisprocess conditions such as the process type, equipment type, reagent type, precursor concentration, temperature, process duration,and pH. Physical and chemical methods have been among the most common methods to synthesize silver nanostructures; however,they possess substantial disadvantages and short-comings, especially compared to green synthesis methods. On the contrary, thenumber of green synthesis techniques has been increasing during the last decade and they have emerged as alternative routestowards facile and effective synthesis of silver nanostructures with different morphologies. In this review, we have initially outlinedthe most common and popular chemical and physical methodologies and reviewed their advantages and disadvantages. Green synthesis methodologies are then discussed in detail and their advantages over chemical and physical methods have been noted. Recentstudies are then reviewed in detail and the effects of essential reaction parameters, such as temperature, pH, precursor, and reagentconcentration, on silver nanostructure size and morphology are discussed. Also, green synthesis techniques used for the synthesis ofone-dimensional (1D) silver nanostructures have been reviewed, and the potential of alternative green reagents for their synthesishas been discussed. Furthermore, current challenges regarding the green synthesis of 1D silver nanostructures and future directionare outlined. To sum up, we aim to show the real potential of green nanotechnology towards the synthesis of silver nanostructureswith various morphologies (especially 1D ones) and the possibility of altering current techniques towards more environmentallyfriendly, more energy-efficient, less hazardous, simpler, and cheaper procedures.
