Summary: We developed a facile synthesis method to prepare nitrogen and phosphorus co-doped carbon quantum dots (NPCQDs) anchored on ZnO nanorods, forming NPCQDs/ZnO (NPCZ) nanohybrid photocatalysts for efficient light-driven hydrogen production. The NPCZ catalyst showed an enhanced hydrogen production rate of 417 μmol/h·g under visible light compared to other photocatalysts. The synergistic interactions between the NPCQDs and ZnO nanorods resulted in the formation of additional energy levels, reduced recombination rate, increased decay lifetime of electron-hole pairs, and improved hydrogen generation performance in the visible region. The experimental results were further supported by Density Functional Theory (DFT), which confirmed the decrease in bandgap and work function as well as the improvement in density of states (DOS) of the NPCZ photocatalyst.

Summary: Large-scale production of green and pollution-free materials is crucial for deploying sustainable clean energy. Currently, the fabrication of traditional energy materials involves complex technological conditions and high costs, which significantly limits their broad application in the industry. Microorganisms involved in energy production have the advantages of inexpensive production and safe process and can minimize the problem of chemical reagents in environmental pollution. This paper reviews the mechanisms of electron transport, redox, metabolism, structure, and composition of electroactive microorganisms in synthesizing energy materials. It then discusses and summarizes the applications of microbial energy materials in electrocatalytic systems, sensors, and power generation devices. Lastly, the research progress and existing challenges for electroactive microorganisms in the energy and environment sectors described herein provide a theoretical basis for exploring the future application of electroactive microorganisms in energy materials.

Summary: A new fluorescence method for sensing dehydroepiandrosterone (DHEA) was introduced in this study. The excessive production of DHEA is the primary characteristic of pediatric adrenocortical carcinoma, and its levels in the bloodstream have the potential to facilitate early cancer diagnosis. A water-dispersed borophene quantum dots (BQDs) sensor was developed for the detection of DHEA, marking its first application. The synthesized BQDs exhibited blue fluorescence under 365 nm UV light and showed a spectral combination at 370/428 nm with a high quantum yield of 24.12%.

Summary: The study introduces borophene decorated with Ag nanoparticles (Ag@B) as a support for Co3O4 catalysts, significantly enhancing the oxygen-evolution-reaction (OER) performance. The improved OER activity of Co3O4-Ag@B is attributed to the increased catalytic sites on Co3O4 facilitated by conductive Ag nanoparticles and the reduced energy barrier for OER rate-determining step due to strong interaction of B atoms with Co and O atoms on Co3O4 nanoplates.
