Summary: In this study, conjugated conductive polymer polypyrrole (PPy) molecules were coated on Ag3PO4 nanoparticles to form a core-shell structure (Ag3PO4@PPy). Ag3PO4@PPy exhibited higher photocatalytic activity and stability under visible light compared to pure Ag3PO4. The enhanced stability and activity were attributed to the inhibitory effect of the PPy shell on Ag3PO4 dissolution, increased contact area through the core-shell structure, and the matched energy level structure and outstanding charge transfer ability of PPy that accelerated the photo-generated charge separation.

Summary: The contamination of water resources is a major environmental concern, especially the presence of hazardous pollutants such as phenol. Therefore, developing cost-effective techniques to remove phenol from water is crucial. This study investigated the use of silver-doped zinc oxide nanorods (Ag-ZnO NRs) for the degradation of phenol under sunlight. The synthesized Ag-ZnO NRs exhibited two distinct structures, hexagonal and cubic, and their optical properties showed significant improvement due to silver doping. The 0.5% Ag-doped ZnO NRs showed the highest photocatalytic activity, achieving a degradation rate of 98.5% for phenol removal under solar light irradiation after 5 hours.

Summary: The desire to improve photocatalytic activity is increasing, especially in semiconductors. Porous photocatalysts have been synthesized to improve surface area and reduce recombination of electron-hole pairs. This paper reviews recent works on porous photocatalysts, with a focus on synthesis and fabrication methods. The topotactic transition technique is the best method for metal oxide porous photocatalysts, while self-organizing blocks are the best method for polymeric porous photocatalysts, especially for growing and fixing 1D semiconductor nanomaterials on 3D and 2D semiconductors on 2D. The hard template method allows for better control of particle shape and size, but the template removal is non-ecofriendly, making the soft template method more favorable. The etching method, on the other hand, is suitable for fabricating porous photocatalysts through a membrane by utilizing the electrical charge created by moving electrons in the electrolyte as a driving force.

Summary: The production of hydrogen from microalgae using palm kernel expeller (PKE) as feedstock was studied. A low thermal pre-treatment method using hydrolysis process was used to improve the hydrogen yield. The results showed that the maximum hydrogen yield was achieved using PKE pre-treated at 90 degrees C for 4 h, with a two-fold increase compared to untreated PKE. The release of inhibitory compounds increased significantly at 50 degrees C, and the kinetics of microalgal hydrogen production followed a zeroth order model.

Summary: Due to the high pollution of palm oil mill effluent (POME) generated as a result of the prosperous production growth of palm oil in Malaysia, there is an increasing concern for environmental conservation. To address this issue, a cutting-edge photocatalytic fuel cell (PFC) system incorporating ZnO/Zn nanorod array (NRA) photoanode, CuO/Cu cathode, and persulfate (PS) oxidant was successfully designed for the treatment of POME and simultaneous energy production. The PFC/PS system exhibited exceptional performance, achieving high COD removal efficiency, open circuit voltage, short circuit current density, and power density under optimal conditions. The stability, durability, and economic viability of the PFC system were also confirmed through recycling tests and electrical energy efficiency assessment. These findings contribute to enhancing the sustainability and economic viability of palm oil production.

Summary: In this study, a comparative investigation on the heterojunction formation between g-C3N4 and Ag-based metal oxides (Ag4V2O7, AgFeO2 and Ag2Mo2O7) catalysts was conducted for the degradation of RB5. The g-C3N4/Ag2Mo2O7 catalyst exhibited the highest photocatalytic activity and demonstrated improved optical properties, charge carrier separation and charge transport. The photocatalytic degradation of RB5 followed the trend: g-C3N4/Ag2Mo2O7 > g-C3N4/Ag4V2O7 > g-C3N4/AgFeO2 > g-C3N4. The g-C3N4/Ag2Mo2O7 catalyst also showed promising reusability without significant loss of photoactivity.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

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.
