“…The future of this research field is focused on developing innovative photocatalytic and photo-electrocatalytic surfaces for microbial inactivation. These solutions should address gaps such as low utilization efficiency of sunlight [18][19][20] and the need for nanostructured photoanodes that can provide better electron transport and oxygen vacancy materials [116,117]. Additionally, synergic connection with other processes such as fuel cells or ozonation can improve disinfection performance [22].…”

“…Current research is concentrating on developing nanostructured surfaces for disinfection using photocatalytic materials and visible light. Recently, new strategies were proposed to overcome the limits of photocatalysts, such as the need to use high-energy UV light, looking toward using visible light-driven photocatalysts [18][19][20]. The ideal material or coating should be activated under artificial light conditions, especially considering the application in a hospital setting [18][19][20][21][22].…”

Photocatalytic technologies represent an innovative method to reduce microbial load on surfaces, even considering recent public health emergencies involving coronaviruses and other microorganisms, whose presence has been detected on surfaces. In this review paper, the antimicrobial efficacy of various photocatalysts applied by different coating methods on different surfaces has been compared and critically discussed. Publications reviewing the use of photocatalytic coatings on surfaces for antimicrobial effectiveness have been examined. Clear search parameters were employed to analyze the PubMed, Scopus, and WOS databases, resulting in 45 papers published between 2006 to 2023 that met the inclusion criteria. The paper assessed various types of photocatalytic coatings that targeted different microbial objectives. Based on the pooled data analysis, the TiO2 coating exhibited a substantial effect in decreasing bacteria strains, both Gram-positive and -negative (99.4%). Although the diversity of these technologies poses significant obstacles to obtaining a comprehensive final assessment of their effectiveness and feasibility for surface application, subgroup analysis indicated significant variations in the removal efficiency of Gram-positive strains based on different surface types (p = 0.005) and time of exposure (p = 0.05). Photocatalytic coatings provide a promising approach to combating the spread of microorganisms on surfaces. Further “in-field” investigations are necessary in the foreseeable future to explore and optimize this novel and exciting health technology.

Currently, over 60% of the world's population lives in cities. Urban living has many advantages but there are also challenges regarding the need for smart urbanization. The next generation of tunable 2D nanomaterials, called MXenes, is the critical enabling technology that can bring the current urban thinking to the next level, called a smart city. The smart city is a novel concept based on a framework of self‐sufficient technologies that are interactive and responsive to citizens’ needs. In this perspective, MXene‐enabled technologies for sustainable urban development are discussed. They can advance self‐sufficient, adaptive, and responsive buildings that can minimize resource consumption, solving the deficiency of essential resources such as clean energy, water, and air. MXenes are at the cutting edge of technological limitations associated with the Internet of Things (IoT) and telemedicine, combining diverse properties and offering multitasking. It is foreseen that MXenes can have a bright future in contributing to the smart city concept. Therefore, the roadmap is presented for demonstrating the practical feasibility of MXenes in the smart city. Altogether, this study promotes the role of MXenes in advancing the well‐being of citizens by raising the quality of urban living to the next level.
