Promoted N N activation by oxygen and boosted ammonia production over Bi4O5Br2

Nitrogen photoreduction method is recognized as a safe, environmentally friendly and sustainable technology for ammonia production. For this method, nevertheless, it is a big challenge to efficaciously activate the NN triple bond. In this work, we mainly investigate the activation of NN bond and the ammonia production reaction over Bi4O5Br2. Under an N2/O2 atmosphere, the ammonia yield reaches 122.8 μmol L−1 over Bi4O5Br2, which is 2.55 times...
