Summary In this paper, titanium dioxide (TiO2) nanoparticles were employed as catalysts towards V2+/V3+ redox couple of vanadium redox flow battery (VRFB). The effect of TiO2 phase on the electrocatalytic performance for negative couple was systematically investigated. The electrochemical properties of TiO2 with different phase were assessed via cyclic voltammetry and electrochemical impedance spectroscopy by using AB as conductive agent. Obtained from the results, anatase TiO2 (α‐TiO2) exhibits superior electrocatalytic activity to rutile TiO2 (γ‐TiO2). The VRFB cell performs well at discharge capacity, voltage efficiency, and energy efficiency by employing α‐TiO2‐modified negative electrode with current density varying between 50 and 100 mA cm−2. The discharge capacity of α‐TiO2‐modified cell with vanadium ion concentration of 1.6 M comes up to 113.5 mA h at 100 mA cm−2 current density, which is increased by 39.1 mA h after modification for negative electrode. Moreover, the corresponding energy efficiency increases by 7.5% after modification of α‐TiO2. Experimental results show that TiO2 is an ideal catalyst for VRFB. Moreover, α‐TiO2 demonstrates superior electrocatalytic performance to γ‐TiO2 towards V2+/V3+ reaction.

“…After five reuse cycles, the degradation rate of BPA still reached 91% by using TiO 2 /TNTs and 95.8% of the material could be separated after 6 h gravity-settling, while the 1.8% BPA was removed and 93% of TiO 2 will lose after gravity settling and cannot be reused in pure TiO 2 group. Besides, Li et al [61], Cheng et al [62], and Ji et al [63] also used titanate materials modified TiO 2 to treated the 4-chlorophenol, phenanthrene, and sulfamethazine, respectively.…”

A high-efficiency method to deal with pollutants must be found because environmental problems are becoming more serious. Photocatalytic oxidation technology as the environmentally-friendly treatment method can completely oxidate organic pollutants into pollution-free small-molecule inorganic substances without causing secondary pollution. As a widely used photocatalyst, titanium dioxide (TiO2) can greatly improve the degradation efficiency of pollutants, but several problems are noted in its practical application. TiO2 modified by different materials has received extensive attention in the field of photocatalysis because of its excellent physical and chemical properties compared with pure TiO2. In this review, we discuss the use of different materials for TiO2 modification, highlighting recent developments in the synthesis and application of TiO2 composites using different materials. Materials discussed in the article can be divided into nonmetallic and metallic. Mechanisms of how to improve catalytic performance of TiO2 after modification are discussed, and the future development of modified TiO2 is prospected.
