Due to such distinct features of TMONPs, these are deemed suitable in applications such as super-capacitors, lithium-ion batteries, non-volatile memory circuits, energy management devices, energy storage, and conversion applications such as solar cells, and infrared detectors. From these discoveries outlined, the identification of specific developments such as catalysis, energy storage, environmental remediation, and biomedical applications can be outdone. This chapter represents a critical evaluation of the synthesis methods, doping techniques, characterization, and recent applications of non-metal doped TMONPs. https://www.materialsciencejournal.org/vol22no1/transformative-potential-of-nonmetal-doped-transition-metal-oxide-nanoparticles-for-multifaceted-applications/ Biomedical nanotechnology Electrocatalysis Environmental remediation Nonmetal doping Photocatalysis Transition Metal Oxides
