“…44 Significantly, the acidic environments (pH = 0) are rarely set in experiments, and it has been reported that CdSe and CdS semiconductor materials are unstable in acidic media and prone to corrosion. 45 To study the water splitting of GaS nanotubes under different conditions, the redox potential for water splitting under acidic (pH = 0) and neutral (pH = 7) was calculated.…”

“…At pH 0, the reduction potential of hydrogen is −4.44 eV and the oxidation potential of water is −5.67 eV. Under normal circumstances, this extremely acidic environment is rarely set up in experiments, and it has also been reported that compounds such as CdS and CdSe are unstable in acidic environments [56]. Therefore, in order to fully understand the water-decomposing ability of JGSSe NTs, the two cases of pH=0 and pH=7 are considered here.…”

The use of sunlight to split water into hydrogen and oxygen is one of the important means to solve the current world energy and environmental problems. In this paper, we use density functional theory to predict the photocatalytic performance of Janus Ga2SSe nanotubes (JGSSe NTs) for the first time. The results show that the small formation energy and strain energy ensure that the nanotubes are stable. The JGSSe NTs also exhibit a wider range of visible light absorption than monolayers, and large radius (>26.60 Å) nanotubes all meet the hydrolysis potential. Surprisingly, the JGSSe NT exhibit an estimated hole mobility of up to 2.89×104 cm2 V-1 S-1.All in all, the JGSSe nanotube exhibit low electron-hole recombination rate, high hole mobility, solar absorption in the visible light range and excellent oxidation ability, which is expected to become an outstanding photocatalyst. In addition, the nanotube band gap can be effectively regulated by applying strain. It is hoped that our research will provide meaningful advances in the development of novel and efficient photocatalysts. We hope that our research will provide a possible way to develop novel and efficient photocatalysts.
