Summary: Salicylaldehyde functionalized chitosan (S-CHIT) was successfully synthesized and attached to the surface of acetylene black paste electrode (ABPE) to construct an electrochemical sensor. The electrochemical behaviors of catechol (CC) and hydroquinone (HQ) on the S-CHIT/ABPE were investigated using cyclic voltammetry (CV) and second-order derivative linear sweep voltammetry (SDLSV). Quantitative determination of CC and HQ was achieved using SDLSV with the oxidation signal. The results demonstrate that S-CHIT/ABPE is a promising electrochemical sensor for the simultaneous detection of CC and HQ.

Summary: Developing efficient and inexpensive electrocatalysts for the hydrogen evolution reaction (HER) is crucial for the commercial viability of electrochemical clean energy technologies. Transition metal phosphides (TMPs) have been recognized as attractive HER catalytic materials due to their abundant reserves, unique structure, tunable composition, and high electronic conductivity. However, the HER activity of TMPs is still limited by various issues and performance bottlenecks. This review addresses these issues, provides explanations and solutions based on the origins of HER catalytic activity in TMPs, presents strategies to improve HER performance, and proposes critical scientific issues for constructing high-efficiency TMP-based electrocatalysts. Challenges and future directions for this research field, including the HER reaction process, catalytic mechanism research, TMP-based catalyst construction, and application expansion, are also discussed.

Summary: The synthesis of three-dimensional interconnected honeycomb-like carbon nanosheets (RTK-3) using homemade phenolic resin, KOH etching, and in situ doping of thiourea resulted in nanosheets with a large surface area (2277.71 m(2) g(-1)) and rich in heteroatoms. This led to outstanding electrochemical performance, with specific capacitances of 349 F g(-1) at 0.5 A g(-1) and 217 F g(-1) at 10 A g(-1). Additionally, the assembled symmetric supercapacitor (RTK-3//RTK-3) showed exceptional performance in different aqueous electrolytes, with energy density of 6.11 W h kg(-1) at a power density of 249.61 W kg(-1) in alkaline electrolytes and a preeminent energy density of 36.34 W h kg(-1) at 810.11 W kg(-1) in neutral electrolytes due to its larger potential window (0-1.8 V). The utilization of resin-based carbon materials to prepare high-performance supercapacitors represents a novel approach and could potentially lead to the application of other large surface area and heteroatom-doped materials in energy storage.
