Environmental protection treatment process relies on the robustness, durability, and performance of catalysts to drive the development of cutting-edge sustainable technologies for the elimination of refractory contaminants. Herein, prepared SrCoO_2.5 were successfully prepared through citric acid by sol-gel method, and further utilized as super catalysts to degrade Rhodamine B (RhB) by coupling with peroxymonosulfate (PMS) in environmental protection. Three optimized parameters (SrCoO_2.5 dosage of 0.2 g L⁻¹, PMS concentration of 0.93 g L⁻¹, and initial pH of 2) were obtained via Conditional test method in environmental protection. Benefiting from the larger specific surface area, pore-volume, and existence of abundant hydroxyl groups, SrCoO_2.5 prepared through citric acid by sol-gel method with more available active sites exhibited an super efficiency of 99.4% toward catalytic degradation of RhB within 10 min under the optimal conditions. Moreover, SrCoO_2.5 demonstrated durability and long-term stability even during the seven consecutive cycle, it almost regenerates in 500 °C for 1 h. The scavenging experiments and electron paramagnetic resonance technologies revealed that non-radical singlet oxygen (¹O₂), sulfate radicals(SO₄•⁻) were associated as active species in the SrCoO_2.5/PMS system. Besides, the reaction mechanism on the SrCoO_2.5 degradation pathways toward RhB was speculated under PMS activation. The results indicated that the synergistic effects between Co–Sr structures not only significantly boosted the removal efficiency and long-term stability of SrCoO_2.5. But also facilitated the redox cycles of Co³⁺/Co²⁺ and Sr³⁺/Sr²⁺, which produce ¹O₂. This proof-of-concept approach to develop such high-efficient Co–Sr structures produced Co³⁺/Co²⁺ and Sr³⁺/Sr²⁺ will open up novel avenues for wastewater decontamination via PMS activation.

环保处理过程依靠催化剂的坚固性、耐用性和性能来推动尖端可持续技术的发展，以消除难处理的污染物。在此，通过溶胶-凝胶法通过柠檬酸成功制备了制备的SrCoO _2.5，并进一步作为超级催化剂通过与过硫酸盐（PMS）偶联降解罗丹明B（RhB）以达到环保目的。三个优化参数（SrCoO _2.5用量为 0.2 g L ^-1，PMS 浓度为 0.93 g L ^-1, 和初始 pH 值 2) 是通过环保中的条件测试方法获得的。受益于更大的比表面积、孔体积和丰富羟基的存在，溶胶凝胶法通过柠檬酸制备的SrCoO _2.5具有更多可用的活性位点，在 10 分钟内对 RhB 的催化降解效率高达 99.4%在最佳条件下。此外，SrCoO _2.5即使在连续七个循环中也表现出耐久性和长期稳定性，它在 500°C 下几乎可以再生 1 小时。清除实验和电子顺磁共振技术揭示了非自由基单线态氧（¹ O ₂）、硫酸根（SO ₄ • ^-) 被关联为 SrCoO _2.5 /PMS 系统中的活性物质。此外，推测在 PMS 激活下SrCoO _2.5降解途径对 RhB的反应机制。结果表明，Co-Sr 结构之间的协同效应不仅显着提高了 SrCoO _2.5的去除效率和长期稳定性。但也促进了 Co ³⁺ /Co ²⁺和 Sr ³⁺ /Sr ²⁺的氧化还原循环，产生¹ O ₂。这种开发这种高效 Co-Sr 结构的概念验证方法产生了 Co ³⁺ /Co ²⁺和 Sr ³⁺/Sr ²⁺将开辟通过 PMS 活化进行废水净化的新途径。
