A new P‐ and F‐co‐doped amorphous carbon nitride (PFCN) has been synthesized via sol‐gel‐mediated thermal condensation of dicyandiamide. Such synthesized P‐ and F‐co‐doped carbon nitride displayed a well‐defined mesoporous nanostructure and enhanced visible light absorption region up to infrared with higher BET surface area of 260.93 m² g⁻¹; the highest recorded value for phosphorus‐doped carbon nitride materials. Moreover, the formation mechanism is delineated and the role of templates was found to be essential not only in increasing the surface area but also in facilitating the co‐doping of P and F atoms. Co‐doping helped to narrow the optical band gap to 1.8 eV, thus enabling an excellent photocatalytic activity for the aqueous reduction of carbon dioxide into methanol under visible‐light irradiation, which is fifteen times higher (119.56 μmol g⁻¹ h⁻¹) than the bare carbon nitride. P doping introduced Brønsted acidity into the material, turning it into an acid‐base bifunctional catalyst. Consequently, the material was also investigated for the thermal conversion of common carbohydrates into furanics.

P和F共掺杂的氮化碳纳米催化剂，用于从糖类中光催化还原CO2和热催化合成呋喃。

通过双氰胺的溶胶-凝胶介导的热缩合反应合成了一种新的P和F共掺杂的非晶氮化碳（PFCN）。这种合成的P和F共掺杂的氮化碳显示出良好的介孔纳米结构，并增强了可见光吸收区，直至红外，BET表面积更高，为260.93 m ²  g ^-1; 掺磷氮化碳材料的最高记录值。此外，描述了形成机理，发现模板的作用不仅在增加表面积，而且在促进P和F原子的共掺杂中都至关重要。共掺杂有助于将光学带隙缩小至1.8 eV，从而在可见光照射下具有出色的光催化活性，可将二氧化碳水还原为甲醇，这是高15倍（119.56μmolg ^-1  h ^-1）。比裸露的氮化碳 P掺杂将布朗斯台德酸度引入材料中，将其转变为酸碱双功能催化剂。因此，还研究了该材料用于将常见碳水化合物热转化为呋喃类物质。
