The design and facile green synthesis of supported metal-engineered nanoparticles with efficient catalytic activity has significant industrial importance. A biosynthetic and ecofriendly one-step reduction strategy has been developed through the protein-mediated in vitro biosynthesis of AgNPs on the surface of nanosilica. The as-synthesized silver nanoparticles supported on nanosilica (Ag@Nanosilica) were characterized by field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDXA) elemental mapping, high resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). The spectroscopic and electron microscopic studies demonstrated that the immobilized protein on the nanosilica surface served as a reducing, capping and stabilising agent, while sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis revealed that the three proteins of 48, 38 and 36 kDa participated in the formation of Ag@Nanosilica material. The formation mechanism of AgNPs on nanosilica explained the origin of the biomineralization of metal nanoparticles in nature. The novel reusable Ag@Nanosilica exhibited enhanced catalytic activity for the hydrogenation of a model compound, namely, 4-nitrophenol. Overall our results will help to understand metal nanoparticle formation in the Earth’s crust and aid the design of “green” syntheses of novel nanoreactors.

Green Chemistry

Green Chemistry provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on, but not limited to, the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998). Green chemistry is the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry is at the frontiers of this continuously-evolving interdisciplinary science and publishes research that attempts to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. Submissions on all aspects of research relating to the endeavour are welcome. The journal publishes original and significant cutting-edge research that is likely to be of wide general appeal. To be published, work must present a significant advance in green chemistry. Papers must contain a comparison with existing methods and demonstrate advantages over those methods before publication can be considered. For more information please see this Editorial. Coverage includes the following, but is not limited to: Design (e.g. biomimicry, design for degradation/recycling/reduced toxicity…) Reagents & Feedstocks (e.g. renewables, CO2, solvents, auxiliary agents, waste utilization…) Synthesis (e.g. organic, inorganic, synthetic biology…) Catalysis (e.g. homogeneous, heterogeneous, enzyme, whole cell…) Process (e.g. process design, intensification, separations, recycling, efficiency…) Energy (e.g. renewable energy, fuels, photovoltaics, fuel cells, energy storage, energy carriers…) Applications (e.g. electronics, dyes, consumer products, coatings, pharmaceuticals, preservatives, building materials, chemicals for industry/agriculture/mining…) Impact (e.g. safety, metrics, LCA, sustainability, (eco)toxicology…) Green chemistry is, by definition, a continuously-evolving frontier. Therefore, the inclusion of a particular material or technology does not, of itself, guarantee that a paper is suitable for the journal. To be suitable, the novel advance should have the potential for reduced environmental impact relative to the state of the art. Green Chemistry does not normally deal with research associated with 'end-of-pipe' or remediation issues.
