Summary: We report a carbon dot (C-dot) superoxide dismutase (SOD) nanozyme with a catalytic activity comparable to that of natural enzymes. The SOD-like activity of C-dot nanozyme relies on specific chemical modifications and conjugated carbonyl groups for binding and electron transfer. Furthermore, the C-dot SOD nanozymes exhibit intrinsic targeting ability to oxidation-damaged cells and effectively protect neuron cells in the ischemic stroke mouse model.

Summary: A durable carbon anode for high-energy-density potassium-ion full cells was constructed using a preferential pyrolysis strategy. By utilizing volatilization of S and N from a pi-pi stacked supermolecule, the anode introduced low-potential active sites of sp(2) hybridized carbon and carbon vacancies, resulting in a low-potential vacancy-adsorption/intercalation mechanism. The as-prepared carbon anode exhibited a high capacity of 384.2 mAh g(-1) (with 90% capacity below 1 V vs. K/K+) and a high energy density of 163 Wh kg(-1) in the potassium-ion full battery. Moreover, the abundant vacancies of carbon improved cycling stability over 14,000 cycles (8,400 hours). This work provides a new synthesis approach for durable carbon anodes with high energy densities in potassium-ion full cells.

Summary: A surface encapsulation method was developed to synthesize HZSM-5 @Al-KIT-6 hierarchical zeolites in order to address the issues of poor mono-aromatic hydrocarbons (MAHs) selectivity and rapid coke deactivation during the catalytic upgrading of lignin pyrolysis vapors. By changing the TEOS/HZSM-5 mass ratio during catalyst synthesis, the acidity and accessibility of the HZSM-5 @Al-KIT-6 hierarchical zeolite can be modulated. The three-dimensional (3-D) cubic mesoporous shell can capture bulky phenolic oligomers and precrack them for further reforming, resulting in improved yield of xylenes and reduced formation of coke deposition.

Summary: It presents the design and synthesis of a durable supported-metal-cluster catalyst Pt@Ge-UTL, in which subnanometric Pt clusters are encapsulated in the extra-large pores of UTL germanosilicate. Through various techniques, it is found that Pt clusters with an average of four atoms are segregated within 14-membered-ring channels by anchoring Pt selectively and directionally to UTL zeolite's unique building units. The host-guest bimetallic structure (Pt-4-Ge-2-d4r@UTL) exhibits high activity, propylene selectivity, and long-term stability for propane dehydrogenation, demonstrating the potential of germanosilicates in the synthesis of high-performance catalysts.

Summary: Carbon materials have excellent stability and diverse structures, making them widely used in various industrial applications. However, activating low-cost carbon materials for efficient catalysis remains a revolutionary and challenging task. In this study, carbon nanotubes (CNTs) encapsulated with transition metal (TM) atoms (TM@CNTs) were used for the hydrogen evolution reaction (HER) with superior activity compared to commonly recognized catalysts. These findings provide a universal strategy for the activation of carbon materials and inspiration for the rational design of carbon-based electrocatalysts for efficient water splitting.
