Coal tar pitch (CTP) is an important chemical by-product of the coking processing of coal. CTP contains polycyclic aromatic hydrocarbons (PAHs) and their derivatives, and it is often used to build and repair roads. To improve the high-value utilization of the PAHs in CTP, researchers have adopted many methods to prepare carbon materials that exhibit superb surface area, excellent electron conductivity, splendid physiochemical stability and wide applications. Herein, the source and properties of CTP are first described. The methods, advantages and mechanism for the preparation of carbon materials from CTP are then described in detail. Second, the applications of carbon materials derived from CTP in supercapacitors, lithium ion batteries, sodium ion batteries, potassium ion batteries, and hybrid capacitors are elaborated. Finally, the major challenges, perspectives and practical strategies for both fundamental studies and applications of carbon materials from CTP have been identified. This review aims to provide insights into the relationships among the preparation methods, structural characteristics, and properties of carbon materials derived from CTP.

Inspired by the CuB site in CcO, a molecular CuII complex (1) featuring a mixed pyridine-phenol ligand has been designed and synthesized. Electrocatalytic and chemical oxygen reduction reactions in the presence of 1 demonstrate a 4e-/4H+ reduction of O2. Kinetic analysis reveals distinct reaction mechanisms for the chemical and electrocatalytic pathways and highlights the crucial role of the ligand backbone in the ORR process.

Designing ultra-specific polar fluorescent probes through the strategy of intramolecular π-π interactions was reported. Based on this strategy, a high-performance lysosomal polarity probe, named P-DOTPA, was developed. It exhibits high specificity, ultra-high sensitivity, near-infrared emission, and the ability to generate superoxide radicals (O2-˙) under irradiation.

We report the synthesis of nanoporous Pt–Pd thin layers on 1.2 μm silica spheres to enhance catalytic efficiency. Amino-functionalized spheres improve metal ion adhesion, enabling crack-free nanoporous layers via electroless deposition with a surfactant template. The resulting structure, with an average pore size of 12 nm, exhibits a uniform and well-defined nanoarchitecture.

A visible-light photoredox catalyzed 1,2-arylalkylation of alkenes with quinoxalin-2(1H)-ones and malonic esters has been developed through direct C(sp2)-H/C(sp3)-H functionalization under mild conditions. A number of quinoxalin-2(1H)-one containing-esters could be obtained in moderate good yields with step and atom-economic manner. This transformation proceeded through a radical process, which features the advantages of mild conditions, clean energy source, wide substrate scope, and favorable functional group compatibility.

Artificial olfactory technology has long been limited by the complexity of chemical signal analysis, resulting in its development lagging behind artificial sensory systems such as vision and hearing. The intervention of artificial intelligence (AI) technology provides core technical support for this field. In this review, we provide an overview of several common gas sensing technologies, focusing on their working mechanisms such as oxygen ionic model, electrochemical reactions, spectral modulation, surface acoustic wave perturbations. In addition, we discussed the advancements enabled by AI, such as deep learning-driven feature extraction and pattern recognition, drift compensation, and deployment on edge devices, as well as the innovations in hardware-software convergence, such as olfactory chips, neuromorphic processors, sensing-storage-computing integration systems. These developments highlight the potential of AI-enhanced gas sensing systems as transformative solutions for achieving ultrasensitive, adaptive, and intelligent detection platforms in diverse real-world applications.
