“…This work demonstrates that ALD is a highly controllable and simple method for the preparation of advanced CDI electrodes, broadening the application of metal oxide/carbon composites in electrochemical processes, especially in the field of photocatalytic degradation of organic pollutants. Furthermore, Ostyn et al [53] prepared TiO 2 film on graphene with ALD and oxidized the surface of graphite. The film has a high UV transmittance of 95%, which simplifies the experimental design.…”

Titanium dioxide (TiO2) photocatalysts, characterized by exceptional photocatalytic activity, high photoelectric conversion efficiency, and economic viability, have found widespread application in recent years for azo dye degradation. However, inherent constraints, such as the material’s limited visible light absorption stemming from its bandgap and the swift recombination of charge carriers, have impeded its broader application potential. Encouragingly, these barriers can be mitigated through the modification of TiO2. In this review, the common synthesis methods of TiO2 are reviewed, and the research progress of TiO2 modification technology at home and abroad is discussed in detail, including precious metal deposition, transition metal doping, rare earth metal doping, composite semiconductors, and composite polymers. These modification techniques effectively enhance the absorption capacity of TiO2 in the visible region and reduce the recombination rate of carriers and electrons, thus significantly improving its photocatalytic performance. Finally, this paper looks forward to the future development direction of TiO2 photocatalytic materials, including the exploration of new modified materials, in-depth mechanism research, and performance optimization in practical applications, to provide useful references for further research and application of TiO2 photocatalytic materials.

“…[ 83 ] Moreover, blister formation could be achieved via the combination of UV transparent anatase thin film and photocatalytic oxidation in the presence of water vapor. [ 84 ] The gas‐assisted photo‐oxidation provided a novel photocatalytic method to uniformly oxidize the graphite surface. Oxidative gas species at reactive atomic carbon surface defects (i.e., GBs) caused graphite surface functionalization and the blistering of basal planes.…”

The intercalating of anions into cost‐effective graphite electrode provides a high operating voltage, therefore, the dual‐ion batteries (DIBs) as novel energy storage device has attracted much attention recently. The “graphene in graphite” has always existed in the graphite cathode of DIBs, but has rarely been researched. It is foreseeable that the graphene blisters with the intact lattice structure in the shell can utilize its ultra‐high elastic stiffness and reversible lattice expansion for increasing the storage capacity of anions in the batteries. This review proposes an expected “blister model” by introducing the high elasticity of graphene blisters and its possible formation mechanism. The unique blisters composed of multilayer graphene that do not fall off on the graphite surface may become indispensable in nanotechnology in the future development of cathode materials for DIBs.
