The Activity of New Materials Surfaces - ternary Semi-conductors with Cationic and Anionic Substitution

Abstract

The article describes the synthesis of solid solutions of ZnS-CdSe, ZnS-CdS, ZnS-ZnTe systems (for the first time in the given compositions). Through X-ray, IR-spectroscopic and electron-microscopic studies, the findings about their bulk physicochemical properties were obtained. These data can be used for certification and determination of their structures. It was determined that solid substitution solutions with preliminary hexagonal structures are formed. According to the results of the acid-base properties investigation, the surfaces of all stated systems components exposed to air have slightly acid nature and offer the increased activity against the basic gases. Generally, the coordinatively unsaturated atoms account for the surfaces acidity. The interrelated laws were found in changing of the acid-base and most essential bulk physicochemical properties on modifying the composition of the series of analogues ZnBIV, CdBIV and the solid substitution solutions formed by them. These laws likely connected to the electron structure of the non-metallic components are used to find the most active adsorbents, primary transducer materials of the sensors for basic gases micro-impurities.
