This review article investigates advances in the research of nanomaterials based on titanium dioxide (TiO2) doped with noble metals and transition metals. Initially, we provide an overview of the theory behind TiO2 as the base material and discuss the fundamental principles of nanomaterial doping. Next, we delve into studies on noble metal doping, highlighting recent research that explores the incorporation of noble metals such as gold (Au), silver (Ag), and platinum (Pt) into TiO2 structures. These studies have revealed significant improvements in photocatalytic and electronic properties, making these materials of interest in various applications, ranging from the photodegradation of pollutants to energy generation. Additionally, we examine transition metal doping, addressing recent studies involving metals such as nickel (Ni), cobalt (Co), and manganese (Mn). These investigations demonstrate the impact of transition metal doping on modifying the properties of TiO2, including its catalytic activity, chemical stability, and conductivity, expanding its potential in areas such as heterogeneous catalysis and energy conversion. Furthermore, we present two tables that showcase other relevant studies, detailing their synthesis methods, applications, and references, providing a comprehensive view of recent research in this ever-evolving field. This article underscores the growing importance of TiO2 nanomaterials doped with noble and transition metals, revealing their promising role in driving innovation in energy and environmental technologies.
