Here, we present the low cost and environmentally friendly photocatalyst, P-doped porous g-C₃N₄/Pd (P-pCN/Pd) for the first time. The designed photocatalyst was fabricated successfully via thermal copolymerization of melamine in the presence of H₃PO₄ as a phosphorous source. In pursuance of comparison, a series of photocatalysts including bulk g-C₃N₄, g-C₃N₄ nanosheets, porous g-C₃N₄, N-doped porous g-C₃N₄, S-doped porous g-C₃N₄, P-doped porous g-C₃N₄, P-doped porous g-C₃N₄/Ag, P-doped porous g-C₃N₄/Cu, and P-doped porous g-C₃N₄/Pd were synthesized. Also, as a result of the calculation, it has appeared that the presence of Pd nanoparticles significantly makes the band gap narrower, facilitates the electron transfer, and increases the catalyst efficiency. Developing photocatalysts for the oxidation of organic materials hold considerable promise for the generation of high-value-added products such as benzaldehyde under visible light irradiation. All materials were characterized physico-chemically and the efficiency of the synthesized photocatalysts was evaluated toward catalyzing benzyl alcohol oxidation to benzaldehyde derivatives. The experiments uncovered that P-doped porous g-C₃N₄/Pd exhibits significant visible light activity at room temperature.

在这里，我们首次提出了低成本和环保的光催化剂，P掺杂的多孔gC ₃ N ₄ / Pd（P-pCN / Pd）。通过在H ₃ PO ₄作为磷源的条件下进行三聚氰胺的热共聚，成功制备了设计的光催化剂。为了进行比较，一系列光催化剂包括块状gC ₃ N ₄，gC ₃ N ₄纳米片，多孔gC ₃ N ₄，N掺杂的多孔gC ₃ N ₄，S掺杂的多孔gC ₃ N ₄，P掺杂的多孔GC₃ N ₄，P掺杂的多孔gC ₃ N ₄ / Ag，P掺杂的多孔gC ₃ N ₄ / Cu和P掺杂的多孔gC ₃ N ₄合成了/ Pd。而且，作为计算的结果，似乎已经发现，Pd纳米颗粒的存在显着地使带隙变窄，促进了电子转移，并且提高了催化剂效率。开发用于氧化有机材料的光催化剂对于在可见光照射下生成高附加值产品（如苯甲醛）具有广阔的前景。对所有材料进行了物理化学表征，并评估了合成光催化剂对苄醇氧化为苯甲醛衍生物的效率。实验发现，掺P的多孔gC ₃ N ₄ / Pd在室温下表现出明显的可见光活性。
