Zhuzhu Zhang et al.

Summary: Constructing photocatalysts with excellent visible light utilization efficiency and high-efficiency photo-generated charge transfer rate is crucial for the photodegradation of organic pollutants in wastewater. In this study, oxygen-doped graphitic carbon nitride (g-C3N4) was prepared and used as a responsive material for a wide range of visible light. CdS nanoparticles were then anchored onto the g-C3N4 to form a Z-scheme heterojunction, which facilitated interfacial charge separation. The results showed that the oxygen-doped g-C3N4/CdS-3 displayed a significantly higher degradation rate for 2-chlorophenol compared to g-C3N4.

Yaohui Li et al.

Summary: Selective electron transport and extraction are crucial for photovoltaic devices. This study presents an electron transport layer (ETL) configuration composed of a solution-processed n-n organic heterojunction to enhance electron transport and boost power conversion efficiency (PCE) in organic photovoltaics (OPV).

Mn(II) Acceleration of the Picolinic Acid-Assisted Fenton Reaction: New Insight into the Role of Manganese in Homogeneous Fenton AOPs

Zhichao Yang et al.

Summary: Mn(II) was found to accelerate the Fenton reaction by participating directly and catalytically in the Fe(III)/Fe(II) redox cycle in the presence of picolinic acid (PICA) as an assisting agent. Mn(II) accelerated Fe(III) reduction, superoxide radical formation, and hydroxyl radical formation, but the proposed Mn(II/III)-H2O2 redox cycle was shown to be insignificant. Instead, Mn(II) initially complexes with a ferric hydroperoxo species, followed by intramolecular electron transfer to give Fe(II) and MnO2+. This scheme can be applied to other Fenton-type systems. These findings will be valuable for the design of practical and sustainable Fenton-based advanced oxidation processes (AOPs) using Mn(II) in combination with chelating agents.
