“…V O affects the recombination rate of electron/hole (e − /h + ) pairs in photocatalysis, altering charge transfer and surface adsorption. Ti 3+ and V O defects impact reactivity and generate ROS, activating molecules of contaminants [16][17][18]. Different strategies, including hydrogenation, thermal reduction, electrochemical reduction, and liquid-phase reduction, have been developed to introduce V O in TiO 2 lattices.…”

This study proposes a simple and controlled method for producing TiO2 with phase junction, oxygen vacancies, and Ti3+ by combining picosecond pulsed laser irradiation and electrochemical anodization. Ti mesh was pretreated by irradiating with a picosecond pulsed laser technique using an Nd:YAG laser (1064 nm) at two fluencies, 15 J/cm2 and 30 J/cm2. The samples were then subjected to electrochemical anodization to form TiO2 nanotube arrays on the previously laser-treated surface. This study will investigate the possibility of forming TiO2 nanotube arrays on a pre-laser-treated Ti substrate and determine their physicochemical and photocatalytic properties. The samples were characterized by FESEM, XRD, Raman, XPS, and UV-Vis DRS. UV-Vis spectroscopy was used to observe the progress of photocatalytic degradation for all samples, and degradation products were determined using GC-MS. With the synergistic effects of phase junction, oxygen vacancies, and Ti3+, the laser-treated TiO2 with 30 J/cm2 showed a higher photocatalytic degradation rate (85.1%) of the pesticide carbofuran compared to non-laser-treated TiO2 (54.8%), remaining stable during successive degradation cycles, which has promising practical applications.

Two‐dimensional (2D) semiconductors with unique structures and surface physicochemical characteristics have been extensively employed for efficient photocatalysis. Recently, surface coordination activation interactions have obtained attention in promoting photocatalytic efficiency as they establish bridges between reactants and photocatalysts. Accordingly, a burgeoning trend in the design of 2D photocatalysts is regulating the surface active centers for coordinating with reactants. These attempts have developed various effective strategies to optimize the 2D photocatalysts and provide in‐depth insights into the structure‐function relationship for heterogeneous photocatalysis. Herein, we summarize recent advances in surface engineering in designing efficient 2D photocatalysts, focusing on coordination activation. We emphasize the advantages of coordination activation as a versatile medium for engineering the surface of photocatalysts. In particular, the discussion includes various strategies for surface engineering and the structure‐function relationship in photocatalysis. This work systematically concludes the significance and future challenges of coordination activation in the surface functionalization of 2D photocatalysis, shedding light on the design of next‐generation photocatalysts.
