| 摘 要： | 使用尿素、 红磷和氯化镍为原料, 通过一种简单的焙烧方法合成了Ni5P4/g-C3N4光催化剂. 该催化剂形成的异质结可以降低界面电阻, 有效抑制光生电子-空穴对复合率. 以罗丹明B模拟污染物进行降解测试, 发现3NPC的反应速率常数最高, 几乎是g-C3N4的7倍, 并具有最高的光催化产氢能力, 制氢速率高达1013.88 μmol·g-1·h-1, 明显高于g-C3N4(664.38 μmol·g-1·h-1).

| Abstract: | Ni5P4/g-C3N4 photocatalysts were synthesized by a simple calcination method with urea， phosphorus and nickel chloride. The formed heterojunction can decrease the interface resistance and photogenerate electron-hole pair recombination rate. These lead to an increase in the catalytic performance of the photocatalyst. In the photocatalytic degradation of RhB， 3NPC（mass fraction of Ni5P4： 3%） has the highest reaction rate constant， which is almost 7 times that of g-C3N4. And 3NPC also exhibits the highest photocatalytic hydrogen activity of 1013.88 μmol·g-1·h-1， which is higher than that of g-C3N4（664.38 μmol·g-1·h-1）. |
