Zn-doped SnS with sulfur vacancies for enhanced photocatalytic hydrogen evolution from water

“…Recently, IV-VI group metal sulfides such as SnS, SnSe, and GeS have attracted great interest due to their narrow band gap and following desirable optoelectronic properties. [20][21][22] In particular, tin(II) sulfide (SnS) has gained increasing interest because of the merits it has, such as abundant reserves, non-toxicity, biodegradable nature, and a suitable electronic band. 23 The indirect band gap of SnS is about 1.2-1.8 eV, which is close to the optimal value for solar energy.…”
