Synthesis of nanorods and nanowires is becoming more and more important due to interest in them in a wide range of disciplines. The genetically engineered tobacco mosaic virus (TMV1Cys) provides a template for synthesis of uniform metal nanorods at mild operating conditions and without the use of any expensive technology compared to conventional synthetic methods. The discovery of the hydrothermal synthetic scheme has allowed the production of higher quality nanorods on the TMV template. However, the mechanism for reduction and growth in this process is still not understood. In this paper, the mechanism of synthesis for producing uniform, controllable palladium nanorods via the hydrothermal synthesis is studied using in situ X-ray Absorption Spectroscopy. Reduction and growth mechanisms are analyzed and valuable information about the nature of the process is acquired. Results in this paper serve as an entryway into fundamentally understanding the relationship between the underlying reduction and growth processes governing mineralization on biotemplates.
