The photocatalytic activities of the semiconductor-based photocatalysts are often practically limited by the insufficient photoinduced charge-carrier separation, so the construction of efficient charge transfer path is vital for highly efficient photocatalysis reaction system. In this study, we reported a rational designed novel hierarchical W₁₈O₄₉/g-C₃N₄ composite with boosted photocatalytic activity through the manipulated flow of dual-channel charge-carrier separation and transfer process. Due to the efficient strategy about the combination of the morphology structure and the regulation of band structure, the prepared composites present enhanced photocatalytic performance in both full-spectrum light and near-infrared (NIR) light irradiation. Under the optimum condition, the prepared W₁₈O₄₉/g-C₃N₄ composites show high degradation efficiency for both colorful methylene blue (MB) and colorless ciprofloxacin (CIP). Mechanistic characterizations and control experiments demonstrate the cooperative synergy effect of dual-channel charge-carrier transfer path in such W₁₈O₄₉/g-C₃N₄ composites, including Z-scheme charge transfer and surface plasmon resonance effect, which interactively leads to the boosted photocatalytic performance. The match of the band gap results in the Z-scheme reaction mechanism and brought both the strong redox ability and promotion of the transfer rate of the photogenerated charges; the LSPR effect of nonmetal plasmonic W₁₈O₄₉ can broaden the light response of the prepared W₁₈O₄₉/g-C₃N₄ to NIR region, leading to enhanced utilization of solar energy. Moreover, the oxygen vacancies in this reaction system which played important role in the photocatalytic process have been fully studied by the appropriate design of the control experiments.

半导体基光催化剂的光催化活性通常受到光诱导的电荷-载流子分离不充分的实际限制，因此有效电荷转移路径的构建对于高效光催化反应系统至关重要。在这项研究中，我们报告了合理设计的新颖分层W ₁₈ O ₄₉ / gC ₃ N ₄通过双通道电荷载流子分离和转移过程的受控流，具有增强的光催化活性的复合材料。由于有关形态结构和能带结构调节的有效策略，所制备的复合材料在全光谱光和近红外（NIR）光照射下均表现出增强的光催化性能。在最佳条件下，制备的W ₁₈ O ₄₉ / gC ₃ N ₄复合材料对彩色亚甲基蓝（MB）和无色环丙沙星（CIP）均显示出较高的降解效率。力学表征和控制实验证明了在这种W ₁₈中双通道电荷载流子传输路径的协同协同效应。O ₄₉ / gC ₃ N ₄复合材料，包括Z方案电荷转移和表面等离振子共振效应，以交互方式提高了光催化性能。带隙的匹配导致Z-方案反应机理，并带来了强的氧化还原能力和光生电荷转移速率的提高。非金属等离子体W ₁₈ O ₄₉的LSPR效应可以加宽制备的W ₁₈ O ₄₉ / gC ₃ N ₄的光响应到近红外区域，从而提高了对太阳能的利用。此外，已经通过适当设计对照实验充分研究了该反应体系中在光催化过程中起重要作用的氧空位。
