“…Conversely, the lower concentration of PMS results in insufficient ROS. 44,45 Moreover, the degradation process complies well with pseudo-first-order kinetics (Fig. 5e), and corresponding k values are 0.01500 min −1 , 0.01684 min −1 , 0.01759 min −1 , 0.01908 min −1 and 0.01849 min −1 , respectively.…”

“…Ding et al prepared CoFe@N-GC materials for catalytic degradation of norfloxacin through activation of PMS . According to the reported Fe-doped Co-based catalysts, most of them exhibited highly efficient catalytic activity by activating oxidant agents (PMS or H 2 O 2 ) in a Fenton-like system. − However, there are rare studies on the removal of antibiotic pollutants over iron-doped Co-based catalysts in photocatalyst systems without any auxiliary oxidants. Therefore, it would be highly desirable to design novel Fe-doped Co-based catalysts that use sunlight as green energy to activate catalysts for degradation pollution and get rid of the usage of any oxidant agents, which would perfectly conform to the green sustainable development idea.…”

The solar light-responsive Fe-doped Co-based coordination polymer (Fe@Co-CP) photocatalyst was synthesized under mild conditions.[Co(4-padpe)(1,3-BDC)] n (Co-CP) was first constructed using mixed ligands through the hydrothermal method. Then, Fe was introduced into the Co-CP framework to achieve the enhanced photocatalytic activity. The optimal Fe@Co-CP-2 exhibited excellent catalytic degradation performance for norfloxacin and ciprofloxacin under sunlight irradiation without auxiliary oxidants, and the degradation rates were 91.25 and 92.66% in 120 min. These excellent photocatalytic properties were ascribed to the generation of the Fe−O bond, which not only enhanced the light absorption intensity but also accelerated the separation efficiency of electrons and holes, and hence significantly improved the photocatalytic property of the composites. Meanwhile, Fe@Co-CP-2 displayed excellent stability and reusability. In addition, the degradation pathways and intermediates of antibiotic molecules were effectively analyzed. The free radical scavenging experiment and ESR results confirmed that • OH, • O 2 − , and h + active species were involved in the catalytic degradation reaction; the corresponding mechanisms were deeply investigated. This study provides a fresh approach for constructing Fe-doped Co-CP-based composite materials as photocatalysts for degradation of antibiotic contaminants.

Entropy‐based polymetallic oxides with configurational entropy, structure flexibility, and crystallographic orientation have been regarded as promising catalysts for oxygen evolution reaction (OER), due to their electronic energy band occupation, composition ligand stabilization, and “cocktail” effect. Herein, a rutile RuIrAgMnO2 oxide with an orientation along the (110) facets is first fabricated by a low‐temperature directional co‐pyrolysis strategy of metal salts on Ti foil at 300 °C. The quaternary oxide exhibits a texture coefficient of 1.13 along (110) facet, resulting from concerted shaping of Ag and Mn components presenting a vibrational entropy of 1.13 R (R is the gas content). In 0.5 m H2SO4, it displays an overpotential of 171 mV at 10 mA cm−2 for OER, running at a voltage for 340 h at 100 mA cm−2. The remarkably improved performance can be associated with the presence of the preferred (110) facets with in‐plane strains, which activate and stabilize OER process via electronic energy band reconstruction. More interestingly, the preferential orientation prevents the diffusion or dissolution of active metal ions caused by entropy‐dependent energy barriers, ensuring long‐term stability. This work can pave the way for entropy‐driven polymetallic oxides with optimal structures, disrupting the trade‐off between activity and stability in water oxidation.
