In the recent times, the demand of the energy and the environmental pollution is the main concern of the global. Due to their significant chemical, physical and magnetic properties spinel-based materials are prominently used in the field of photocatalysis and water splitting. In the present report is emphasis on the fundamental’s understandings for their size, shape, chemical and the degradation of various pharmaceutical drugs, pesticides, and textile dye materials. This report explained the way of formation, characteristics and the wide applications of the spinel-based materials in the vast energy and environmental research. Based on the future prospectus of the energy and the cost effectiveness this spinel-based materials plays an important role in hydrogen generation as well as in catalytic activities.
