Summary: Developing PDI-based photocatalysts with different substitutes, the Se-HPDI/g-C3N4 heterojunction showed the highest H2O2 production rate of 224.27 μM h-1 under visible light, which is 10.1 times higher than bare g-C3N4. The enhancement is attributed to the disparity of electron distribution between different constituent layers in heterojunctions, facilitated by the introduction of substitutes at the bay position. Additionally, the load of PDIs broadens the optical absorption range of g-C3N4 and suppresses H2O2 decomposition. This work provides inspiration for the further design of PDI-based photocatalysts.

Summary: In this paper, porous g-C3N4 nanosheets with carbon vacancies (Cv-PCNNS) were developed for efficient metronidazole degradation via the photocatalysis-self-Fenton system. The carbon vacancies in the Cv-PCNNS accelerated photo-induced charge separation and improved O2 activation. The Cv-PCNNS also provided H for photocatalytic O2 reduction to H2O2 and captured H from the surroundings to restore their original appearance. The introduction of carbon vacancies increased the H2O2 production rate and enhanced the metronidazole degradation efficiency.

Summary: Designing photocatalysts with high light utilization and efficient photogenerated carrier separation is crucial for pollutant degradation. In this study, a hierarchical core shell material alpha-Fe2O3@ZnIn2S4 with a tandem heterojunction mechanism and MXene Ti3C2 quantum dots (QDs) was synthesized. The alpha-Fe2O3@ZnIn2S4/Ti3C2 QDs exhibited significantly higher photodegradation efficiency compared to pure alpha-Fe2O3. The enhanced photocatalytic activity was attributed to the S-scheme heterojunction and Schottky junction tandem, which facilitated charge separation. This study provides a new approach for the construction of tandem double heterojunctions for pollutant degradation.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
