本文报道了以α-Fe_2O_3∶Nd_2O_3∶SO_4~=型超强酸作为光催化剂,利用可见光合成氨的研究。发现在α-Fe_2O_3中同时掺入Nd_2O_3及SO_4~=,可使氨的光催化合成比较稳定,并对这一过程的机制进行了讨论。
This paper reports the synthesis of ammonia by visible light using α-Fe_2O_3: Nd_2O_3: SO_4 ~ = superacid as a photocatalyst. The results show that Nd_2O_3 and SO_4 ~ = can be doped into α-Fe_2O_3 simultaneously to stabilize the photocatalytic activity of ammonia. The mechanism of this process is also discussed.
