Abstract

The rising pollution of aquatic ecosystems due to industrial dyes makes it essential to create efficient strategies for remediation. In this study, we synthesized an unusual Cu₂O/Pt photocatalytic Fenton-like catalyst through heterojunction engineering and high-temperature modification of cuprous oxide, with platinum nanoparticles serving as a cocatalyst to enhance charge separation and catalytic efficiency. Under near-infrared light irradiation, the Cu₂O/Pt catalyst exhibited remarkable photothermal performance, rapidly achieving elevated temperatures that further accelerated the degradation of methylene blue. degradation experiments indicated that the Cu₂O/Pt catalyst achieved over 99 % removal efficiency, outperforming pure Cu₂O by facilitating greater hydroxyl radical generation through enhanced hydrogen peroxide decomposition. The enhanced degradation efficiency is attributed to the synergistic effect between Cu₂O and Pt, which not only expands the effective pH range but also ensures the reproducibility and durability of the catalytic process. The results underscore the Cu₂O/Pt system's advantageous potential for practical applications in wastewater treatment, offering an effective and sustainable approach to reduce industrial water pollution.

六方Cu2O/Pt光热与光fenton协同降解染料污染物

由于工业染料对水生生态系统的污染日益严重，因此必须制定有效的补救策略。在这项研究中，我们通过异质结工程和氧化亚铜的高温改性，合成了一种不同寻常的Cu2O/Pt光催化Fenton-like催化剂，以铂纳米粒子作为助催化剂，提高了电荷分离和催化效率。在近红外光照射下，Cu2O/Pt催化剂表现出显著的光热性能，快速达到较高的温度，进一步加速了亚甲基蓝的降解。降解实验表明，Cu2O/Pt催化剂的去除率超过99%，通过增强过氧化氢分解促进羟基自由基的生成，从而优于纯Cu2O。Cu2O和Pt之间的协同作用提高了降解效率，不仅扩大了有效pH范围，而且保证了催化过程的再现性和持久性。结果表明，Cu2O/Pt体系在废水处理中具有良好的实际应用潜力，为减少工业废水污染提供了有效和可持续的途径。
