This mini-review aims to present the current status of knowledge about cobalt oxide Co3O4 nanoparticles more precisely obtained by solution combustion synthesis, which is a process characterized by its high reaction rate and low cost. Unique features of cobalt (II)(III) oxide Co3O4 nanoparticles are size between 12 and 60 nm, and high surface area and porosity that enhances their performances in fields such as energy storage, environmental and sensing applications. By analysis of various synthesis parameters such as fuel-to-oxidizer ratios, precursor materials, and thermal conditions, this review elucidates how these factors influence particle characteristics and functionality. Furthermore, while extensive research highlights the efficacy of Co3O4 nanoparticles in energy applications, there is a notable need to further studies focusing on their environmental applications, appealing to young scientists to come up with improved solution seeking innovative research areas of nanotechnology and material science. The review offers more avenues for using Co3O4 nanoparticles in solving some of the pressing global environmental issues.
