The effects of Eu doping on the structure and electrochromic performance of crystalline WO₃, as well as the synergistic performance of the dual-doped dual-phase laminated films and their assembled devices, were systematically investigated. Results showed that the 10 mol% Eu-c-WO₃ film exhibited optimal electrochromic performance: its coloring/bleaching response time (t_c /t_b) was 4.21 s/6.97 s (faster than undoped c-WO₃), bleached transmittance at 633 nm was 80.1% with an optical modulation (ΔT) of 33.6%, and good cycling stability after 2000 cycles. The oxidation/reduction Li⁺ diffusion coefficients reached 5.12 × 10⁻¹¹/7.33 × 10⁻¹¹ cm²/s, which were attributed to the doping of Eu³⁺ inducing lattice defects that facilitate ion migration. 3Mo-a-WO₃/10Eu-c-WO₃ laminated film achieved further performance enhancement: compared with the undoped a-WO₃/c-WO₃ reference system, its t_c/t_b was shortened to 2.9 s/5.8 s, with a ΔT of 71.1% and a coloration efficiency (CE) as high as 78.2 cm²·C⁻¹, while retaining stable performance after 2000 cycles, which was attributed to the synergistic effect of dual-doped and dual-phase complementarity. Electrochromic devices (ECDs) assembled with 3Mo-a-WO₃/10Eu-c-WO₃ laminated film as the working electrode, ITO glass as the counter electrode, and 1 mol/L LiClO₄/PC as the electrolyte exhibited t_c/t_b of 3.2 s/6.3 s, CE of 69.5 cm²·C⁻¹, and ΔT of 65.2%, respectively.

In this study, nickel‑iron oxide (NiFe₂O₄) nanospheres synthesized by a sol-gel method were used as precursors to prepare graphite sheet-supported nano‑nickel‑iron alloy catalysts (NF/G) via an in-situ carbothermal reduction method. The effects of carbothermal reduction temperature on the catalyst's composition, microstructure, and OER performance were systematically investigated. The results show that the nano‑nickel‑iron alloy catalyst obtained at 1000 °C (Fe_0.64Ni_0.36/G-1000) exhibits the best OER performance, with overpotentials of 220, 316, and 380 mV at current densities of 10, 100, and 200 mA cm⁻², respectively, a Tafel slope of 86.61 mV dec⁻¹, and excellent stability (only a 5% decline over 100 h). This performance is significantly better than that of similar catalysts. The superior performance is attributed to three main factors: First, Fe_0.64Ni_0.36/G-1000 possesses the highest content of the active phases, Ni³⁺ (21.15 mol%) and Fe³⁺ (68.60 mol%), leading to high intrinsic OER activity. Second, the difference in electronegativity between Ni³⁺ (1.695) and Fe³⁺ (1.651) creates a NiOOH → FeOOH micro-electric field within the catalyst, facilitating charge transfer during OER. Third, the highly active amorphous FeOOH layer formed on the Fe_0.64Ni_0.36 surface features Fe³⁺ with high coordination numbers and low oxidation potential. Under an external electric field, it establishes a low-energy-barrier Fe³⁺ ↔ Fe⁴⁺ detour pathway, which optimizes the high-energy-barrier direct pathway Ni³⁺ → Ni⁴⁺, thereby significantly reducing the reaction energy barrier of the rate-determining step (*O → *OOH) in OER. This leads to a notable decrease in the catalyst's overpotential and Tafel slope.
