Description

Application

• Development and characterization of ZnO, Au/ZnO and Pd/ZnO thin films through their adsorptive and catalytic properties.: This paper discusses the synthesis and catalytic applications of ZnO-based thin films, where 1-butene serves as a probe molecule to study adsorption and catalysis, contributing to advancements in material science and catalysis technology (Giannoudakos et al., 2008).

Packaging
