摘要

The authors report the biosynthesis of gold nanoparticles (Au-NPs) using plant pathogenic (MTCC 2210). The synthesis of nanoparticles was characterised by visual observation followed UV-visible spectrophotometric analysis, Fourier transform infrared spectroscopy and nanoparticle tracking analysis. Later, direct methanol fuel cell (DMFC) was constructed using two chambers (anodic chamber and cathodic chamber). These Au-NPs as catalysts have various advantages over the other catalysts that are used in the DMFC. Most importantly, it is cheaper as compared with other catalysts like platinum, and showed higher catalytic activity because of its effective surface structure. Being nano in size, it provides more surface area for the attachment of reactant molecules (methanol molecules). The DMFC catalysed by Au-NPs are found to be suitable to replace lithium ion battery technology in consumer electronics like cell phones, laptops and so on due to the fact that they can produce a high amount of energy in a small space. As long as fuel and air are supplied to the DMFC, it will continue to produce power, so it does not need to be recharged. The use of Au-NPs as catalyst in DMFC has not been reported in the past; it is reported here the first time.
