Platinum loaded NaNbO3-xNx with nanostep surface nanostructures toward enhanced visible-light photocatalytic activity

A green chemistry process for environmental purification is realized on a novel visible-light-active Pt loaded NaNbO3-xNx photocatalyst. The apparent quantum efficiency (AQE) of Pt-NNON sample with nanostep surface structures for IPA photodegradation achieved up to 8.6% at the wavelength of 419 nm.
