Summary: This study reports a defect-rich and sulfur-doped short amorphous carbon nanotubes as a potential anode material for high-performance lithium-ion batteries (LIBs). The defect-rich structures induced by sulfur doping and the amorphous nature of the carbon nanotubes improve the performance of LIBs by providing additional active adsorption sites, good electrolyte/electrode interfacial compatibility, and improved diffusion kinetics of Li ions. First-principle calculations also show that sulfur doping can create additional defects that favor Li ions adsorption, enhance conductivity, and reduce Li ions diffusion barrier. This work presents an effective strategy for designing superior electrode materials for LIBs.

Summary: By appropriately substituting Nb for W in WSe2, the thermoelectric performance of WSe2 can be significantly improved, with the thermopower (S) increased by about 10 times to 5.44 mu W cm-1 K-2 (at 850 K) and the lattice thermal conductivity (kappa L) reduced from 1.70 to 0.80 W m-1 K-1. The increase in power factor (PF) is attributed to the increased hole concentration and enhanced thermopower (S), while the decrease in kappa L is mainly due to phonon scattering at point defects NbW. A record high figure of merit max of about 0.42 is achieved at 850 K for the doped sample W0.95Nb0.05Se2, which is about 13 times larger than that of pristine WSe2, demonstrating the effectiveness of Nb doping at the W site in improving the TE performance of WSe2.

Summary: Controlling the structure of semiconductors is crucial for tailoring their physicochemical and photoelectronic properties. Graphitic carbon nitride has shown potential in photocatalysis, but its photocatalytic activity is limited by the rapid recombination of charge carriers. In this study, we demonstrate that introducing potassium doping and nitrogen defects into graphitic carbon nitride can enhance visible light absorption, improve charge separation, and significantly enhance the photocatalytic behavior for water splitting.

Summary: The integration of heteroatom doped carbon nanotubes and cobalt phosphide through simultaneous phosphorization and carbonization method demonstrates an effective bifuctional oxygen reduction and evolution catalysis. The in-situ generated Co2P weakens the catalytic graphitization effect of metallic Co during carbonization, leading to the formation of more pyridinic-N species. The resultant Co2P/doped-CNTs catalyst shows outstanding ORR and OER performances, making it a promising air-cathode catalyst for rechargeable zinc-air batteries.

Summary: Peroxymonosulfate (PMS)-based advanced oxidation processes are promising water treatment technologies. The redox cycle between transitional metals in heterogeneous catalysis is crucial for PMS activation and efficient pollutant removal. In this study, Ni-Fe (hydr)oxides demonstrated high PMS activation ability, degrading 96.8% trichloroethylene (TCE) in 40 minutes with specific Fe, Ni, and PMS dosages. The catalyst normalized TCE degradation rate constant reached 1.48 L g-1 min- 1. Reactive species generated through nonradical and radical pathways contribute to the degradation and dechlorination of TCE in the Ni-Fe (hydr)oxides/PMS system.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
