“…For the pristine NCoHPOF, the bands at 1420 and 3310 cm À 1 can be attributed to the NH 4 + cation. It is worth noting that for different calcined sample, such as NCoHPOF-450, NCoHPOF-500, NCoHPOF-550, and NCoHPOF-600, the bands at 920 and 1044 cm À 1 could be found, which are due to the antisymmetric and symmetric PÀ OÀ P stretching in P 2 O 7 4À anions, [40][41] thus suggesting the formation of pyrophosphate cobalt, consistent with the above TGA and XRD.…”

Transition‐metal phosphates have been widely applied as promising candidates for electrochemical energy storage and conversion. In this study, we report a simple method to prepare a N, F co‐doped mesoporous cobalt phosphate with rich‐oxygen vacancies by in‐situ pyrolysis of a Co‐phosphate precursor with NH4+ cations and F− anions. Due to this heteroatom doping, it could achieve a current density of 10 mA/cm2 at lower overpotential of 276 mV and smaller Tafel slope of 57.11 mV dec−1 on glassy carbon. Moreover, it could keep 92 % of initial current density for 35 h, indicating it has an excellent stability and durability. Furthermore, the optimal material applied in supercapacitor displays specific capacitance of 206.3 F g−1 at 1 A ⋅ g−1 and maintains cycling stability with 80 % after 3000 cycles. The excellent electrochemical properties should be attributed to N, F co‐doping into this Co‐based phosphate, which effectively modulates its electronic structure. In addition, its amorphous structure provides more active sites; moreover, its mesoporous structure should be beneficial to mass transfer and electrolyte diffusion.

“…5a shows that a peak appeared at 1160 cm −1 in the FTIR of [43]. This P-O − peak, however, slightly shifts to a higher wavenumber side with the presence of La 3+ , indicating that the combination of La 3+ and P-O − affects its wavenumber [44]. This confirms the formation of stable chelates of PP-La via P-O − bond in PP.…”

personal protective equipment (PPE) is of vital importance to radiation protection safety of nuclear personnel involved. [4][5][6] Currently, the PPE is fabricated with rubber-based composites containing high atomic number (high Z) fillers such as lead (Pb), tungsten (W), and bismuth (Bi). [7][8][9][10][11] Although it has various merits such as flexibility for wearability, its poor permeability for air and water vapor is negative to channel sweat away during work, which causes reduced wear comfort and then affects working efficiency. [12,13] Therefore, it is urgent to develop flexible materials with permeability for enhanced wear comfort and radiation protection safety of PPE.Many studies have attached importance to fabrics bearing heavy metals to meet the requirements. This is due to the fact that overlapped fabrics shield high-energy photons meanwhile offer curving passages for permeability. Coating high-Z fillers on textiles has the ability to shield highenergy photons while it tends to be peeled off and reduce permeability. [14][15][16][17][18][19] Alternatively, polymer fibers containing high-Z fillers for fabrics seems to address wear comfort meanwhile radiation shielding safety. Some high-Z fillers, such as Bi 2 O 3 , WO 3 , Bi 2 WO 6 , and BaSO 4 , have been intensely applied to fabricated various polymer fibers for shielding X-rays. [20][21][22][23][24][25] Note that current polymer fibers are generally filled with no more than 40 wt% fillers. This is due
