a XRD patterns of the Cu2O-TiO2 NTA heterojunction samples. Sample S0: pure anatase TiO2 NTA sample; samples S2, S4, and S5: thermally decomposed sample with immersing in 0.1, 0.3, and 4 mol/L Cu(Ac)2 solution, respectively. b EDS result of the Cu2O-TiO2 NTA heterojunction films, showing the existence of elements Ti, Cu, and O. The results confirm the successful loading of Cu2O on the TiO2 NTAs
