Abstract
Gas detection is crucial, especially with regard to environmental pollution. Air pollution by toxic gases impacts not only on the contamination of the air itself, but also causes damage to the soil and water. Therefore, early prevention of environmental pollution issues becomes an urgent necessity. One of the efforts that can be done is to build a reliable gas detector based on functional materials, such as magnetite or zincite. However, preparing well-structured materials for gas sensing purposes is a challengeable task for many scientists and engineers. In this study, we synthesis the nano-sized cobalt-doped magnetite particles which were reinforced with micron-sized zincite. The composites were subjected to crystal structure characterization. We also discussed the theoretical basis for the composites as the possible gas sensing materials.
