Fine ZnS powder is an efficient photocatalyst, which produces hydrogen gas from water upon illumination. Sulfur vacancies can be introduced in ZnS during its synthesis; this gradually turns the white-yellowish ZnS into a brown powder, and boosts the photocatalytic activity through enhanced light absorption.
Compounds with zinc in the oxidation state +1 are extremely rare. [5] The compounds have the formula RZn 2 R and they contain a Zn — Zn bond analogous to the metal-metal bond in mercury(I) ion, Hg 2 2+. In this respect zinc is similar to magnesium where low-valent compounds containing a Mg — Mg bond have been characterised. [6]
Lithopone, C.I. Pigment White 5, is a mixture of inorganic compounds, widely used as a white pigment powder. It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. It was made popular by the cheap production costs, greater coverage.

Common phases include ZnS, SnS, CuS, and Cu 2 SnS 3. Identification of these phases is challenging by traditional methods like X-ray diffraction (XRD) due to the peak overlap of ZnS and Cu 2 SnS 3 with CZTS. Some impurities such as ZnS and Cu 8 GeS 6 can be selectively removed from the CZTS or CZGS by treatment with hot diluted HCl. [9]
