A sinter-resistant, tri-phasic catalyst made of platinum (Pt), titanium dioxide (TiO2), and silica (SiO2) has been developed by researchers at Georgia Institute of Technology in the US. The catalyst has the much sought after “islands in the sea” configuration, in which the Pt nanoparticles are fully exposed, making them completely accessible to the reagents in a catalytic reaction. The system, which works efficiently at temperatures of up to 700 °C, might be ideal for use in the three-way catalytic converter…………
