摘要：

The directional migration of S-vacancy is beneficial to the separation of photogenerated carriers and the transition of electrons in semiconductors. In this study, Bi(x)/Bi(2-x)S(y)@carboxylic-cellulose (CC) photocatalyst with bionic chloroplast structure is obtained by electron beam irradiation to induce S-vacancy in Bi(2)S(3)@CC. The results of CO(2) photoreduction experiments demonstrate that the reduction rate of CO(2) to CH(3)OH by Bi(x)/Bi(2‒x)S(2.89)@CC-450 samples is 10.74 µmol·g(-1)·h(-1), and the selectivity is 92.82%. The results...
