Photoassisted synthesis of manganese oxide nanostructures using visible light at room temperature
Literature Information
Lavinia Balan, Loïc Vidal
A green chemistry approach was successfully used in this work to synthesize manganese oxide nanoparticles with different shapes and crystalline phases. This approach is based on the visible light irradiation (445 nm) at room temperature of an aqueous solution of a manganese(II) salt in the presence of an alkaline hydroxide (NaOH, KOH or LiOH). Several experimental parameters, i.e., the nature of the precursor salt, hydroxide concentration, hydroxide type, irradiation time and the atmosphere, were tuned and their influence on the morphology and the structure of the nanoparticles was studied by transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectroscopy. A diversity of manganese oxide phases (λ-MnO2, γ-Mn3O4 and MnO(OH)) were obtained. It must be emphasized that these compounds were easily and fairly quickly synthesized at room temperature, without surfactants and, moreover, by using an environmentally friendly method. In addition, the successful control of the size and the shape of the nanoparticles allowed to obtain a variety of nanoparticles morphologies ranging from one-dimensional (1-D) to three-dimensional (3-D) nanostructures (i.e., spherical, nanorods, nanoflowers, nanocubes). This synthetic approach could be readily extended to other transition metal oxides.

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.
