Jilin University Zhang Tong Team | Bio-inspired Room Temperature NO₂ Sensor: π-Back Bonding Mechanism Achieves High Selectivity Detection

Inspired by the interaction between metal porphyrins (such as hemoglobin) and gas molecules in nature, the Zhang Tong team at Jilin University has successfully developed a conductive polymer composite material (PANI/PEDOT:PSS) functionalized with copper tetraphenylporphyrin (CuTPP) for high selectivity NO₂ detection at room temperature. This sensor utilizes the unique π-back bonding mechanism between CuTPP and … Read more

Plasmon-Induced Ultrafast Interfacial Charge Transfer for Enhanced Photocatalytic Hydrogen Evolution

The localized surface plasmon resonance (LSPR) effect of noble metals plays a crucial role in photocatalytic hydrogen evolution by efficiently injecting hot electrons generated by plasmons into the photocatalytic system, significantly modulating the interfacial electron transfer dynamics. However, the specific impact of noble metal LSPR effects on ultrafast interfacial charge transfer and its kinetic characteristics … Read more

Efficient Carrier Separation via Ru@TS@C Zeolite: Enabling Photo-Cathodes for High-Efficiency Photo-Assisted Metal−Air Batteries

Neutral aqueous zinc-air batteries (ZAB) show promise for extended lifespan and recyclability compared to alkaline systems, but are hindered by limited energy efficiency and slow kinetics of power output. Recently, Ji-Jing Xu and Huan-Feng Wang from Jilin University reported an effective method for near-neutral ZABs based on photo-responsive titanium silicate molecular sieve TS-1. Key Points … Read more

Electrochemical Impedance Spectroscopy Relaxation Time Distribution (EIS-DRT) Analysis of Lithium-Sulfur Battery Electrode Processes

Electrochemical Impedance Spectroscopy (EIS) is a widely used, simple, practical, and non-destructive technique in battery analysis. However, traditional analytical techniques can only provide an overall performance of all electrochemical processes within the battery, and much useful information remains vague or difficult to obtain. This poses a major challenge when analyzing complex chemical systems using EIS, … Read more

Morphology-Controlled Long-Range Photogenerated Charge Carrier Transfer Pathway for Enhanced Photocatalytic Hydrogen Production

This study successfully prepared controllable π-π conjugated stacking of T-ZnTPyP and H-ZnTPyP through thermal regulation. The high temperature effectively restricted the participation of water molecules in the T-ZnTPyP stacking structure, enhancing the thermal stability of the material and accelerating the short-range migration rate of photogenerated charge carriers. Field Overview: Photocatalytic water splitting for hydrogen production … Read more
