2,4-Dichlorophenol (DCP) is one of the high-risk sources of contaminating water resources, which is very difficult for biodegradation. In this contribution, sulfonated nickel phthalocyanine (NiPcS) was loaded onto mesoporous KIT-6 through functionalization of the solid support and electrostatic anchorage of the dye. The materials were characterized using standard instrumental methods in every step of the preparation. High catalytic activity was noticed for the degradation of DCP under visible light. The results showed that the photocatalyst had converted nearly 90% of DCP under visible light with optimum operating conditions of 25 mg of catalyst, natural pH (pH 6), and 30 mg L⁻¹ of DCP also, chemical oxygen demand (COD) were determined. The photo-degradation rate of DCP fits well with the pseudo first-order kinetics and, the nonlinear least-squares analysis, which is common for photocatalytic reactions. The catalyst reusing is simple and it was found that it remarkably preserves 94% of its activity following four consecutive cycles of use.

2,4-二氯苯酚（DCP）是污染水资源的高风险来源之一，很难对其进行生物降解。通过这种贡献，通过固相载体的功能化和染料的静电锚固，将磺化的酞菁镍（NiPcS）加载到中孔KIT-6上。在制备的每个步骤中，使用标准仪器方法对材料进行表征。注意到在可见光下DCP的降解具有高催化活性。结果表明，在25 mg催化剂，自然pH（pH 6）和30 mg L ^-1的最佳操作条件下，光催化剂在可见光下已转化了近90％的DCP。还测定了DCP的化学需氧量（COD）。DCP的光降解速率与拟一级动力学和非线性最小二乘分析非常吻合，这对于光催化反应是很常见的。催化剂的重复使用很简单，并且发现在连续四个使用周期后，它可以显着保留94％的活性。
