Low crystalline flowerlike cobalt silicate hydroxide (Co₃(Si₂O₅)₂(OH)₂, CoSiO_x) is synthesized by the mineralization of NH₄Cl. Abundant highly active ≡Co-OH⁺ is preformed on the surface of CoSiO_x, while the low crystallinity of CoSiO_x leads to the formation of active ¹O₂ caused by the generation of oxygen vacancy in the valence change cycle between Co²⁺ and Co³⁺. The optimal CoSiO_x with a high specific surface area of 665.2 m² g^-1 could expose surface ≡Co-OH⁺, thus rapidly activate PMS and accelerate catalytic efficiencies. As a result, at least 11 kinds of organic pollutants could be degraded with 33-242% higher efficiencies than reported. In addition to the common SO₄·- and ·OH, large amounts of active ¹O₂ endow the CoSiO_x/PMS system with superb catalytic performances in diverse conditions, suggesting the excellent adaptability for practical usage. This work provides a new protocol to advance the PMS activation process for high-performance cobalt based heterogeneous catalysts.
