Full-spectrum photocatalysis from ultraviolet to near infrared has generated immense scientific interest in environmental purification and energy conversion, which is still a huge challenge. Herein, we utilized a solution combustion method to prepare W₁₈O₄₉/N-doped reduced graphene oxide (N-rGO) hybrid nanomaterials for full-spectrum photocatalytic degradation, which degraded organic dye molecules within a short reaction time (45 min) and demonstrated a high degradation rate (more than 90%) and a low initial concentration of degradation (50 mg L⁻¹). Moreover, the relationship between irradiation light source, temperature, time, photocatalytic properties and photocatalytic mechanism of the degraded organic dye molecules have been investigated. This research afforded a full-spectrum photocatalyst for effectively removing organic dyes under any wavelength range of sunlight, whether UV, Vis or NIR light.

W18O49 / N掺杂的还原氧化石墨烯杂化体系结构，用于全光谱光催化降解水中的有机污染物

从紫外到近红外的全光谱光催化在环境净化和能量转换方面产生了巨大的科学兴趣，这仍然是一个巨大的挑战。本文中，我们采用溶液燃烧法制备了W ₁₈ O ₄₉ / N掺杂的还原型氧化石墨烯（N-rGO）杂化纳米材料，用于全光谱光催化降解，该有机材料在较短的反应时间内（45分钟）降解了有机染料分子。表现出较高的降解率（超过90％）和较低的初始降解浓度（50 mg L ^-1）。此外，研究了降解的有机染料分子的照射光源，温度，时间，光催化性能和光催化机理之间的关系。这项研究提供了一种全光谱光催化剂，可在任何波长的日光下有效地去除有机染料，无论是紫外线，可见光还是近红外光。
