The application of artificial mussels in conjunction with transplanted bivalves to assess elemental exposure in a platinum mining area
(MDPI, 2020)There is increasing evidence that platinum group elements (PGE) are pollutants of emerging concern worldwide. Limited information exists on levels, particularly in regions where PGEs are mined. A passive sampling device ... -
Density functional theory calculation of Ti3C2 MXene monolayer as catalytic support for platinum towards the dehydrogenation of methylcyclohexane
(Elsevier, 2020)The need for sustainable energy systems and reducing greenhouse gas emissions are key drivers in the development of liquid hydrogen organic carriers (LOHCs). Density functional theory calculations were performed on the ... -
Development of a Pt/stainless steel mesh catalyst and its application in catalytic hydrogen combustion
(Elsevier, 2019)In this paper, different methods to prepare a Pt/stainless steel mesh catalyst for catalytic hydrogen combustion are reported. Pt was deposited as a thin layer onto stainless steel mesh as a support matrix. Thermal treatment ... -
Evaluation of polycrystalline platinum and rhodium surfaces for the electro-oxidation of aqueous sulfur dioxide
(Springer, 2016)Polycrystalline Rh and Pt were studied to ascertain their electrocatalytic activity for the electro-oxidation of SO2, an important reaction in sulfur dioxide depolarized electrolyzers used to produce hydrogen. Cyclic ... -
Interaction of H2O with the Platinum Pt (001), (011), and (111) surfaces: a density functional theory study with long-range dispersion corrections
(ACS, 2019)Platinum is a noble metal that is widely used for the electrocatalytic production of hydrogen, but the surface reactivity of platinum toward water is not yet fully understood, even though the effect of water adsorption on ... -
Interaction of SO2 with the Platinum (001), (011), and (111) surfaces: a DFT study
(MDPI, 2020)Given the importance of SO2 as a pollutant species in the environment and its role in the hybrid sulphur (HyS) cycle for hydrogen production, we carried out a density functional theory study of its interaction with the Pt ... -
Laser induced H2 production employing Pt-TiO2 photocatalysts
(Elsevier, 2013)The photocatalytic production of hydrogen from water as well as from an aqueous methanol solution employing pre-treated TiO2 and various Pt-TiO2 photocatalysts was studied by using an Nd:YAG laser as irradiation source. ... -
Metal accumulation in riverine macroinvertebrates from a platinum mining region
(Elsevier, 2020)South Africa is the world’s main supplier of Pt. The Bushveld Igneous Complex in South Africa contains 75% of the world’s Pt resources. Mining of this precious metal requires large volumes of water for production and removal ... -
Photocatalytic reduction of platinum(II and IV) from their chloro complexes in a titanium dioxide suspension in the absence of an organic sacrificial reducing agent
(Elsevier, 2014)The thermodynamics and surface chemistry affecting the photocatalytic reduction of chloro aqua platinum( II) and platinum(IV) complexes as means of platinum recovery from solution are communicated. The photocatalytic ... -
Thermally stable Pt/Ti mesh catalyst for catalytic hydrogen combustion
(Elsevier, 2020)In this study, platinum (Pt) supported on titanium (Ti) mesh catalysts for catalytic hydrogen combustion were prepared by depositing Pt as a thin-layer on metallic or calcined Ti mesh. The Pt thin-layer could be stabilized ...
