Summary: Semiconductor photocatalysis is a promising and sustainable approach for wastewater treatment. However, its practical application is hindered by limited energy utilization, insufficient mineralization, and low treatment capacity under sunlight. This account summarizes the progress in developing broad-spectrum responsive supramolecular organic photocatalysts capable of achieving over 95% pollutant mineralization under sunlight. By modulating molecular dipole and crystallinity, the built-in electric field is enhanced, improving charge separation and photodegradation rates. Furthermore, integrating the Fenton catalyst in a photo-self-Fenton system overcomes the low-flux constraints of traditional photocatalysis, realizing high-flux mineralization under sunlight.

Summary: This study assessed the aggregation and photooxidation of nanoplastics (NPs) in natural waters using nanosized polystyrene (PS) as an example, and investigated the effects of dissolved organic matter (DOM) using Suwannee River fulvic acid (SRFA) as representative DOM. The results showed that simulated sunlight irradiation had negligible effects on PS aggregation, while SRFA enhanced heteroaggregation through hydrophobic interactions. Photooxidation of PS was observed in SRFA solutions, leading to an increase in the O/C ratio on its surface. The study provides insights into the environmental behavior of NPs in natural waters.

Summary: With the rapid development of the economy and industry, water pollution has become increasingly serious due to the excessive chemical wastes that need to be removed via reduction or oxidation reactions. Simultaneous removal of dual pollutants through photocatalytic redox reactions has been extensively studied in the past five years as it effectively decontaminates pollutants compared to single pollutant systems. This review classifies binary pollutants selectively removed through photocatalytic reduction or oxidation according to heavy metal-organic pollutants, heavy metal-heavy metal pollutants, and organic-organic pollutants. The intrinsic relationship between pollutants is explained through three different mechanisms, and strategies for enhancing this treatment method are discussed. This review provides a recent perspective on the development of photocatalysis systems for industrial applications.

Summary: By regulating the atomic environment of high-entropy-alloy (HEA) electrocatalysts, inactive sites can be transformed into active sites, leading to enhanced catalytic activity. A high-entropy FeCoNiCuMn HEA nanoparticle was synthesized by integrating low-electronegativity Mn and high-electronegativity Cu with Fe, Co, and Ni base metals, which facilitated the transformation of inactive Cu to electron-enriched active sites. This resulted in reduced adsorption energies of reactants, intermediates, and products, leading to improved hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) activity. The HEA exhibited superior electrocatalytic activity and cycling stability, surpassing Pt/C and IrO2 catalysts. This work represents a breakthrough in the design of advanced HEA electrocatalysts for complex reactions.

Summary: A C2+-producing catalyst was designed by incorporating a boron dopant into porous copper oxide nanotubes (B-CuO NTs) using an electrospinning-calcination method. The B-CuO NTs catalyst achieved a 60.5% C2+ Faraday efficiency, including 47% ethanol, which is a 4-fold increase compared to CuO in a flow cell. The introduction of boron dopant enhanced the adsorption of *CO on B-CuO NTs, facilitating hydrogenation reactions and promoting C-C coupling to form *OCCHO intermediates.

This method expands the application of covalent organic frameworks (COFs) in electrochemical sensing and shows great potential for nitrite detection in food and environmental fields.

Summary: Tuning the electronic structure of the active centers in covalent organic frameworks (COFs) is crucial for balancing the adsorption ability and reactivity of oxygen in the 2e(-) oxygen reduction reaction (ORR) for electrocatalytic synthesis of hydrogen peroxide (H2O2). By introducing different by-design building blocks, the adsorption ability of oxygen molecule (O-2) can be finely tuned, and the binding strength of O-2 is positively correlated with the electron-donating ability of the active center. The newly designed TP-TD-COF exhibits higher 2e(-) ORR activity and selectivity due to its stronger electron-donating ability and higher adsorption strength of O-2 on the electron-rich active center. This work reveals the fundamental structure-activity relationship in H2O2 synthesis and provides a strategy for designing metal-free COF catalysts through rational modulation of their electronic properties at the molecular level.
