Summary: Peroxynitrite (ONOO-) is a major reactive oxygen species that plays important roles in cellular signal transduction and homeostatic regulation. Fluorescence imaging technology using fluorescent probes offers advantages such as simplicity, high sensitivity and selectivity, real-time, and nondestructive detection for precise detection of ONOO- in biological systems. Ratiometric fluorescent probes, with built-in calibration of emission bands, have been extensively used to monitor bioactive species by preventing interference from the biological environment. This review discusses the chemical structures, response mechanisms, and biological applications of small-molecule ratiometric fluorescent probes for ONOO- in live cells or in vivo, as well as the challenges and future prospects.

Summary: Graphitic carbon nitride hollow tubes co-doped with carbon and phosphorus (CPCN) were developed as visible light photocatalysts. The hollow tubes exhibited improved catalytic activity due to the increased active sites and visible light harvesting ability. The co-doping of carbon and phosphorus resulted in a narrower band gap and faster charge transfer, leading to enhanced catalytic performance. The study demonstrates the synergistic effect of carbon and phosphorus co-doping on promoting photoinduced charge transfer and inhibiting recombination.

Summary: In this study, N, O co-doped hierarchical porous carbons (HPCs) were fabricated directly from soybean meal through the molten salt method. The resulting HPCs exhibited a well-developed 3D hierarchical porous structure with a high specific surface area, facilitating ion storage and transmission. By incorporating abundant heteroatoms into the carbon materials, additional pseudocapacitance was achieved. The HPC-3 electrode demonstrated a maximum specific capacitance of 507 F g-1 in 1 M H2SO4 electrolyte and the supercapacitor cell assembled from HPC-3 electrodes exhibited a relatively high energy density of 12.4 Wh kg-1 at a power density of 50 W kg-1. This research highlights the potential application of KHCO3 as a pore-forming agent and the obtained high-performance electrode material for supercapacitors.

Summary: The effect of structural properties of fluorinated graphene (FG) on the supercapacitive properties in KI additive electrolyte was investigated. The adjustment of porous structure and surface F element content of FG through chemical reduction and heating treatment led to a dramatic increase in specific capacitance in KI additive electrolyte compared to pure H2SO4 electrolyte. The relationship between F content and areal capacitance revealed that a small amount of F content, particularly semi-ionic C-F species, can effectively promote the areal capacitance. The assembled symmetric supercapacitor with moderate F content and high specific surface area exhibited an energy density of 8.89 Wh kg-1 and long cyclic stability.

Summary: Zinc phytate was used as a sacrificial template to synthesize porous carbon for supercapacitors. The resulting carbon material had a hierarchically porous structure with a specific surface area of 1125 m(2) g(-1). Adjusting the pore structure was achieved by introducing KOH during the preparation of the phytate salt, leading to an increase in micropore content. The introduction of in-situ K activation instead of KOH activation resulted in the formation of dual-metal phytates and contributed to the micropores in the prepared carbon material. With increased microporosity, the specific capacitance of the carbon material improved.

Summary: A facile one-step approach was developed to construct N-doping carbon-encapsulated metal catalysts (M@N-C, M = Fe, Co, and Ni) for CO2 electroreduction to CO. Among them, the Ni@N-C catalyst achieved an excessive CO Faraday efficiency (FECO) (> 90%) on a broad achievable potential window (-0.67 V to -0.97 V vs RHE) in the H-type cell. In the flow cell, the optimized catalyst achieved a FECO of 98% and an industrial-relevant current density of 430 mA cm-2 at -1.07 V vs RHE. This work provides a facile way to fabricate catalysts on a large scale with preeminent performance for industrial CO2 electroreduction to CO.

Summary: We synthesized a carbon nanotubes-en-capsulated Ni nanoparticles catalyst through a facile chemical vapor deposition approach for electrochemical CO2 reduction (ECR). The Ni@N-C catalyst exhibited the highest CO Faraday efficiency (FECO%) of 90% at -0.77 V vs. RHE in the H-type cell. Moreover, it showed a high FECO% of over 93% within the range of -0.37 to -0.77 V vs. RHE in the flow cell. The excellent catalytic performance of Ni@N-C suggests that N-doped carbon nanotubes coated on Ni nanoparticles play a vital role in promoting ECR activity. This work provides insights into the development of a simple and efficient electrocatalyst for ECR.
