    students bulk carbon| article | university of pretoria

    Carbon black is an ideal absorber material given its very small cross-section. In this project carbon black from recycled scrap tyres is combined with concentrated solar energy to induce vaporisation and flashing in a custom built flow cell. The vapor is condensed to yield purified drinkable water

    nanoporous cubic silicon carbide photoanodes for enhanced

    Cubic silicon carbide (3C-SiC) is a promising photoelectrode material for solar water splitting due to its relatively small band gap (2.36 eV) and its ideal energy band positions that straddle the water redox potentials. However, despite various coupled oxygen-evolution-reaction (OER) cocatalysts, it commonly exhibits a much smaller photocurrent (<∼1 mA cm–2) than the expected value (8 mA
