Summary: Developing economic and efficient adsorbents is crucial for removing antibiotic residuals from contaminated water. Nitrogen-doped porous graphene-like carbon (NPGC) adsorbents were successfully synthesized and showed a high removal capacity for TC. The adsorption mechanism of TC onto N-doped carbon adsorbents was systematically studied, and NPGC demonstrated potential environmental application, including anti-interference capacity and reusability.

Summary: The ternary-nanocomposite Pd-polypyrrole/nitrogen-doped graphene (Pd-PPy/NGE) was facilely prepared by the one-pot method, showing promising electrocatalytic properties for alcohol oxidation in alkaline medium. The outstanding performance can be attributed to the well dispersion of Pd nanoparticles, the porous and stable three-dimensional structure of the composite, and the synergistic effect between different components. The structural randomness of the conducting polymer and the potential synergistic effect between the metal nanoparticles and various supports offer broad development space for these composites as electrocatalysts in direct alcohol fuel cell applications.

Summary: Based on density functional theory calculations, it was found that Mo atoms serve as the real active sites in the MoFeS4/GR catalyst, allowing for nitrogen fixation with good selectivity. Charge was identified as the main factor affecting the catalyst's nitrogen fixation activity. The role of Mo atoms is to provide electrons while Fe atoms transport electrons in the catalyst.

Summary: Exploring cost-effective non-precious metal electrocatalysts is vital for large-scale clean energy conversion devices. In this study, a three-dimensional cobalt sulfide/multi-heteroatom co-doped carbon composite was synthesized and exhibited outstanding electrocatalytic performance for the oxygen reduction, oxygen evolution, and hydrogen evolution reactions. The optimized material showed comparable or even superior performance to commercial counterparts and also demonstrated excellent anti-poisoning capability. The results provide an effective strategy for the design and synthesis of efficient and durable cobalt chalcogenide-based electrocatalysts.

Summary: Solar-driven interfacial evaporation is a promising approach to address water scarcity. A 3D-porous N-doped lignosulfonate/graphene oxide aerogel (NLGA) was prepared by a one-step hydrothermal method. The NLGA showed excellent evaporation rate and efficiency under 1 sun illumination, surpassing foam-based solar evaporators. It also maintained stable evaporation rate without salt accumulation due to its rich-pore structure and superhydrophilicity.
