Abstract

Via a simple bottom-up approach, a complex quaternary oxynitride system (Zn1.7GeN1.8O) was prepared in the form of small nanoparticles (d~ 15 nm), which were stable and morphologically well-defined. The Zn1.7GeN1.8O nanoparticles exhibited a band gap of 2.4 eV and were active towards photocatalytic degradation of organic dyes.

Highlights

  • Via a simple bottom-up approach, a complex quaternary oxynitride system (Zn1.7GeN1.8O) was prepared in the form of small nanoparticles (d $ 15 nm), which were stable and morphologically welldefined

  • In the 1970s Levy and Boudart investigated the catalytic activity of some metal carbides with isoelectronic properties similar to that of noble metals.[5,6]

  • As well as their related nitrides, are promising materials with properties such as superior hardness, strength, and corrosion resistance. Their electronic character may be in uenced by chemical composition changes, which allow for the design of materials with metallic, semiconducting, or isolating properties.[7]
