Integration of AgPO/WO photoanode with bifunctional CuO cathode exhibiting photocatalytic and peroxidase-mimetic properties for nanozyme-coupled photoelectrocatalytic degradation of persistent pollutant.

The nanozyme-coupled photoelectrocatalytic (PEC) technology, which integrates the semiconductor photovoltaic effects with the enzyme-mimetic properties of nanomaterials, offers a promising and sustainable approach for removing organic contaminants from wastewater. In this study, a dual-photoelectrode PEC system comprising an AgPO/WO anode and a bifunctional CuO cathode was investigated for the efficient degradation of 2,5-dichlorophenol (2,5-DCP). Under simulated solar irradiation, the AgPO/WO photoanode demonstrated superior PEC activity for 2,5-DCP degradation and HO production.

Near-infrared-driven dual-photoelectrode photoelectrochemical sensing for fumonisin B1: Integrating a photon up-conversion bio-photocathode with an enhanced light-capturing photoanode.

Fumonisin B1 (FB1), the most prevalent and highly toxic mycotoxin within the fumonisins family, poses threats to humans, especially in children and infants, even at trace levels. Therefore, it is essential to design an easy and sensitive detection strategy. Herein, a brand-new dual-photoelectrode photoelectrochemical (PEC) sensing platform for FB1 detection under near-infrared irradiation was unveiled.

Portable self-powered electrochemical aptasensing platform for ratiometric detection of mycotoxins based on multichannel photofuel cell.

Self-powered electrochemical sensors based on photofuel cells have attracted considerable research interest because their unique advantage of not requiring an external electric source, but their application in portable and multiplexed targets assay is limited by the inherent mechanism. In this work, a portable self-powered sensor constructed with multichannel photofuel cells was developed for the ratiometric detection of mycotoxins, namely ochratoxin A (OTA) and patulin (PAT). The spatially resolved CdS/BiS-modified photoanodes and a shared Prussian Blue cathode were integrated on an etched indium-tin oxide slide to fabricate the multichannel photofuel cell.
