Concave octopus-like PtCu nanoframe mediated photo-electro Fenton catalysis for fast organic dyestuff elimination

Abstract

In this work, a photo-electro Fenton catalytic nanoplatform based on concave octopus-Like PtCu nanoframes was fabricated for organic dyestuff degradation. The electrochemical oxidizing reaction was taken to generate hydrogen peroxide...

Nanoframes as a Resilient Candidate for a Broader Spectra of Catalysis Challenges

“…The use of photo-electro Fenton electro catalysts like concave octopus-like Pt-Cu nanoframes (COPC-NFs) has been reported to improve wastewater treatment and eliminate dyes [99]. In comparison to the previous Fenton processes reported, the photo-electro Fenton method has shown better results due to its self-production of hydrogen peroxide [99] and also due to the use of copper instead of iron in the Fenton catalyst, which shows enhanced efficiency in a neutral environment.…”

Fenton's degradation can be enhanced by considering NIR signals [100,101].…”

Nanoframes as a Resilient Candidate for the Solution of Broader Spectra of Catalysis Challenges

“…Photo-electro Fenton electro catalysts like concave octopus-like Pt-Cu nanoframe (COPC-Nfs) have been reported for better wastewater treatment to eliminate dyes [95]. In comparison to previous Fenton processes reported, the photo-electro Fenton method has shown better results due to the selfproduction of hydrogen peroxide [95] and due to copper instead of iron used in the Fenton catalyst which depicts enhanced efficiency in a neutral environment. Fenton's degradation can be enhanced by considering NIR signals.…”

Platinum based theranostics nanoplatforms for antitumor applications

“…Electrodynamic therapy embodies an exceedingly potent and minimally intrusive tumor treatment, which operates by instigating the breakdown of water molecules, instigating the production of reactive oxygen species in response to an electric field, and henceforth eradicating cancer cells. 24 Among palladium and iridium nanoparticles, platinum nanoparticles manifest the most substantial electrocatalytic efficacy. Thus, electrocatalytic nanomaterials implemented in electrodynamic therapy research are currently dominated by platinum nanoparticles.…”
