The textile industry is responsible for most of the consumption and inappropriate disposal of organic and highly toxic pollutants, such as dyes. Therefore, it is necessary to remediate polluting molecules before returning the water to the environment. Photocatalysis is a promising method for dye molecule degradation as it can provide complete mineralization through an efficient photocatalytic process. CuWO₄ exhibits a band gap of 2.40 eV and can be excited with visible light, making it economically advantageous for industrial-scale applications. In this work, CuWO₄ was synthesized by coprecipitation (CM), microwave-assisted hydrothermal (HM), and polymeric precursor (PPM) methods to evaluate the photocatalytic behavior in response to the different characteristics obtained from the synthesis routes. In photocatalytic measurements for OH· radical generation, the sacrificial agent H₂O₂ was used, and in order to delay the recombination process sodium oxalate and silver nitrate scavengers were applied under visible light. CuWO₄ synthesized by PPM was more efficient in the dye degradation when the Ag⁺ scavenger was used, indicating that the predominant reaction mechanism was by direct oxidation or hydroxyl radicals. The surface charge (− 38.5 (PPM), − 29.7 (CM), and − 16.2 mV (HM)) influence was more relevant than the specific surface area (1 (PPM), 22 (CM), and 21 m² g⁻¹ (HM)) of the samples in the photocatalytic process. The complete degradation occurred in 80 min for the samples obtained by CM and HM and only 20 min were necessary for the sample synthesized by PPM.

纺织工业是造成有机染料和高毒性污染物（例如染料）的大部分消费和不当处置的原因。因此，有必要在将水返回到环境之前补救污染分子。光催化是用于染料分子降解的有前途的方法，因为它可以通过有效的光催化过程提供完整的矿化作用。CuWO ₄的带隙为2.40 eV，可以用可见光激发，因此在工业规模的应用中具有经济优势。在这项工作中，CuWO ₄通过共沉淀法（CM），微波辅助水热法（HM）和聚合前体（PPM）方法合成了SnO2，以评估响应于从合成途径获得的不同特性的光催化行为。在光催化测量OH·自由基的过程中，使用了牺牲剂H ₂ O ₂，并且为了延迟重组过程，在可见光下施加了草酸钠和硝酸银清除剂。当Ag ⁺时，PPM合成的CuWO ₄在染料降解方面更有效。使用了清除剂，表明主要的反应机理是通过直接氧化或羟基自由基。表面电荷（ - 38.5（PPM）， - 29.7（CM），以及- 16.2毫伏（HM））影响比比表面积（1（PPM），22（CM）更相关，并21米²克^{- 1}（HM））的样品在光催化过程中。CM和HM获得的样品在80分钟内发生了完全降解，而PPM合成的样品仅需要20分钟。
