Two new heterogeneous catalysts (Cu-sand) have been synthesized by supporting copper on the surface of natural sand using two defined methods such as chemical vapor deposition (CVD) and dry evaporation (DE). The Cu-sand catalysts were characterized by several techniques. SEM-EDX analysis indicated that 13.86 wt% of copper species were dispersed on the surface of Cu-sand (CVD) catalyst whereas 11 wt% were agglomerated on the Cu-sand (DE) surface. The presence of copper species was more noticeable in the XRD pattern for the Cu-sand (CVD) catalyst. The catalytic performance of the prepared catalysts was evaluated in the Fenton-like oxidation of Alizarin red S dye (ARS). The reactivity and stability of the two catalysts were differentiated by studying the influence of the supported amount of copper, activity of leachate and the reuse of catalyst on the conversion of initial concentration of ARS. ARS oxidation has been investigated under various experimental conditions. The best ARS conversion rate was about 95% when using Cu-sand (CVD) catalyst in optimal conditions: [H₂O₂]₀ = 10 mmol/L, temperature = 40 °C and the addition of H₂O₂ in two stages (0 min and 20 min of treatment). CVD method makes it possible to prepare an efficient and stable catalyst.

通过使用化学气相沉积（CVD）和干式蒸发（DE）等两种定义的方法，将铜负载在天然沙子的表面上，已经合成了两种新型的非均相催化剂（铜砂）。通过多种技术对铜砂催化剂进行了表征。SEM-EDX分析表明13.86wt％的铜物质分散在Cu-砂（CVD）催化剂的表面上，而11wt％聚集在Cu-砂（DE）的表面上。对于铜砂（CVD）催化剂，铜的存在在X射线衍射图中更为明显。在茜素红S染料（ARS）的芬顿样氧化中评价了所制备催化剂的催化性能。通过研究铜负载量的影响，区分了两种催化剂的反应性和稳定性。渗滤液的活性和催化剂的再利用对ARS初始浓度转化的影响。已在各种实验条件下研究了ARS氧化。在最佳条件下使用铜砂（CVD）催化剂时，最​​佳ARS转化率约为95％。₂ O ₂ ] ₀ = 10 mmol / L，温度= 40°C，并分两个阶段（处理0分钟和20分钟）添加H ₂ O ₂。CVD方法可以制备有效且稳定的催化剂。
