Alone or in composites with other materials, they find numerous applications in plasmonic photocatalysis [7

Although, various methods of efficient control and monitoring of waste management have been

• , noble metals work as an electron pool retarding the recombination of charge carriers [41][42][43], whereas under visible-light irradiation titania is activated by the plasmonic properties of noble metals (“plasmonic photocatalysis”) [44][45]. Accordingly, it has been proposed that the combination of the

It is proposed that inactivation of bacteria under visible light irradiation is mainly caused by plasmonic photocatalysis, i.e., the activation of titania by

This includes the type of noble metal and semiconductor photocatalyst together with their morphology, porosity, crystallinity, contact

• immediate plasmonic photocatalysis compared to other plasmonic metals because they are more chemically resistant and stable to standard atmosphere [170]. Under LED excitation at 530 nm in the presence of air or oxygen, Au NPs could promote the oxidation reaction of 9- anthraldehyde to form anthraquinone as
