Surface modification through nanomaterials deposition is highly promising method for enhancing the pool boiling heat transfer across various energy applications such as wastewater and incinerator heat recovery, thermal management of battery and electronics device cooling. The diverse enhancement techniques have been studied to improve heat transfer, with nanoparticle coating emerging as the most effective method for various energy and environmental applications. TiO2 stands out for its exceptional structure, electrochemical characteristics, chemical stability, non-toxic, and feasibility. The TiO2 nanorods and nanotubes structures exhibit superior photocatalytic scheme because of enhanced delocalization and diminished charge recombination. The surface characteristics are influenced by several factors, including materials, nanoparticles size, thermal conductivity of the nanomaterial, nanomaterial deposition techniques, thickness of the coating layer, concentration of nanofluid. Among the various deposition techniques explored, electrochemical deposition stands out as particularly advantageous due to its simplicity, cost-effectiveness, excellent adhesion properties, and ability to control surface characteristics such as coating thickness, porosity, and wettability through modulation of current density. During the electrochemical deposition process, the emergence of hydrogen bubbles from the surface generated a significant quantity of cavities. This phenomenon increases the surface porosity and roughness as related to bare substrate. The surface wettability has been found to be an important surface parameter affecting the dry-out occurrence which significantly influenced by the surfaces’ topological and chemical characteristics.
