Abstract Gaseous mercury (Hg) emissions from man-made sources pose a significant environmental concern. From the three species of mercury (Hg0, Hg2+, HgP) that are emitted, elemental mercury (Hg0), which emanates from coal powered power plants, ore processing and incineration, is the most common. Currently, the method for removing mercury from flue gases is based on carbon adsorption. Thus, determining an effective, efficient and economically viable substitute for the removal of mercury is highly desirable. An alternative method, which is utilised in this study, involves oxidising elemental mercury to its mercuric form (Hg2+) and capturing it in an aqueous solution. In this work, two transition metal oxides were investigated for their ability to catalyse the oxidation of elemental mercury. Nano particulate forms of hematite (alpha-Fe2O3,) and Nickel Oxide (Ni2O3), were prepared and characterized using a range of techniques (XRay Diffraction, Transmission Electron Microscopy and BET Surface Area Analysis). The mercury oxidation efficiency of the synthesized nano transition oxides were investigated under varying conditions and compared with average % Hg oxidation values of 70.80% and 2.49% respectively.
