Abstract
In this research, Au nanoparticles (NPs) modified HNTs/g-C 3 N 4 /CdS composite (HCAC-3) photocatalyst was prepared for highly-efficient photocatalytic reaction. SEM and TEM results confirmed that the g-C 3 N 4 was uniformly wrapped on the surface of HNTs, and Au and CdS NPs were also loaded on the surface of the HNTs/g-C 3 N 4 composite. Photo-electrochemistry tests and density functional theory calculation results showed that the introducing Au NPs speeds up the photo-electric conversion and separation ratio of photogenerated carriers inside the catalyst. Additionally, the CO 2 photoreduction experiments showed that the yields of CO and CH 4 with HCAC-3 catalyst after 4 h irradiation with UV-Vis light were about 55.4 and 8.6 μmol/g, respectively, which were about five times the performance of HNTs/g-C 3 N 4 composite and the HCAC-3 has great photocatalytic stability. Besides, the photodegradation experiment of tetracycline aqueous solution showed that the HCAC-3 composite has excellent photodegradation activity. After 120 min, the tetracycline photodegradation ratio of HCAC-3 was about 87.4%, which is about 2.2 times higher than that of HNTs/g-C 3 N 4 composite. Finally, the synergistic effect of g-C 3 N 4 /CdS type II heterojunction and the LSPR effect of Au NPs were investigated and determined as the main reasons for the improvement of the photocatalytic performance of the g-C 3 N 4 -based catalyst. • HNTs/g-C 3 N 4 /Au/CdS was prepared for CO 2 photoreduction and TC degradation • The dispersion of active sites was greatly enhanced by the loading of HNTs • Au NPs speed up the carriers’ separation efficiency in g-C 3 N 4 /CdS heterojunction
