Mesoporous ZnS thin films prepared by a nanocasting route
Mesoporous metal chalcogenides (e.g., ZnS, CuS, and derived mixed sulfide or selenides) show an extremely high potential in technological areas like catalysis, sensors, environmental protection, and photovoltaics. Although chemical bath deposition methods allow obtaining stable and porous metal chal...
