General description

Platinum (Pt) is a highly ductile, malleable and unreactive metal. It is resistant to corrosion and stable at high temperatures. Although resistant to hydrochloric and nitric acid, it dissolves readily in hot aqua regia to form chloroplatinic acid.

Application

Pt wire may be used :
  • as a microelectrode-indicator electrode in voltammetry
  • as a transvascular embolic agent
  • to study chronopotentiometry of hydrogen peroxide with a platinum wire electrode or
  • in gas detection instruments.

Traditional antibacterial photocatalysts are primarily induced by ultraviolet light to elicit antibacterial reactive oxygen species. New generation visible-light responsive photocatalysts were discovered, offering greater opportunity to use photocatalysts as disinfectants in our living environment. Recently, we found that visible-light responsive
