Summary: Magnetized activated carbons (MAC) prepared from rape straw powder showed high adsorption capacities for Pb(II) and Cd(II) due to surface active points, with adsorption behavior conforming to the Freundlich model and pseudo-second-order kinetic model. Thermodynamic parameters indicated spontaneous and endothermic reactions. Adjusting the pH of the solution could enhance adsorption capacity, but competitive adsorption occurred in the presence of high-valent ions. Adsorption mechanisms included electrostatic attraction, surface complexation, and co-precipitation. The MAC material showed potential for heavy metal ion removal from aqueous solutions.

Summary: In this study, phosphorus-doped Fe7S8 nanowires integrated within carbon were successfully synthesized, with a typical porous structure providing abundant active sites, leading to reduced overpotentials for hydrogen and oxygen evolution reactions. The doping of phosphorus effectively enhanced the electron density of Fe7S8 and weakened Fe-H bonding, resulting in a decrease of adsorption free energy barrier on active sites.

Summary: Direct growth of orthorhombic Ta3N5-type Ta-O-N compound thin films with different atomic fractions on Si and sapphire substrates was achieved using unbalanced magnetron sputtering. Increasing the total pressure led to higher oxygen incorporation and a decrease in nitrogen and tantalum fractions in the films, resulting in a decrease in lattice constant. The increase in oxygen incorporation also resulted in a widening of the optical bandgap and a transition from crystalline Ta3-xN5-yOy to amorphous O-rich Ta-O-N compound films.

Summary: In this study, uniform Ag@AgP2@Ni-CoP@C core-shell nanowires have been synthesized using a template-engaged strategy. The merging of conductive Ag core with active AgP2 and porous carbon-coated Ni-doped CoP shells favors the mass and electron transfers, effectively lowering the activation energy toward the reduction of N2 to NH3. The titled catalyst achieved a high NH3 yield of 16.84 μg h-1 mg-1 cat. at -0.4V (vs. RHE) and a high Faradaic efficiency of 21.7% at -0.3V vs. RHE, as well as high electrochemical and structure stability.
