“…If the separation is unable to reach the atomic level, the active center cannot be fully exposed, which affected the energy storage performance of MOF-235. Zhao et al studied the graphene doped TiO 2 mesoporous materials for photocathode protection [21]. The graphene doped TiO 2 mesoporous materials were prepared by the sol-gel method under ultrasonic radiation.…”

The growing interest in energy storage has led to the urgent need for the development of high-performance cathode electrodes. The commercialized materials MOF-235 and TiO2-P25 exhibit characteristics that may be suitable as electrodes but there are inherent challenges that have yet to be addressed in the literature. In this study, a high-pressure hydrothermal synthesized MOF-235 and sol-gel-made TiO2-P25 were tested for battery performance. The results indicate that MOF-235 does not possess the desired performance due to uncontrollable agglomeration. On the other hand, TiO2-P25 showed good cycling life, and the performance can be further optimized by doping and minimizing the particle size. Additionally, SEM and TEM were applied for surface characterization, providing evidence that mesoporous TiO2-25 inhibits photo-generated carrier recombination. The mesoporous energy storage mechanism of those two materials is also discussed. This research will provide technical support for the industrialization of those two mesoporous materials.

“…Photosynthesis in nature achieves a highly efficient solar energy conversion mainly through combining several different molecules to arrange the nanoscale, which indicates the importance of a technique for the site-selective coupling of different materials to realize artificially efficient devices [1][2][3]. TiO 2 is a kind of safe, stable, and cheap material, which has attracted significant research interest [4][5][6][7][8][9]. Photo-catalytic reactions on the semi-conductive surfaces of TiO 2 materials are widely investigated and reported for the purposes of (1) water splitting to produce H 2 and (2) eliminating pollutants from water and air [10][11][12][13][14][15].…”

As an environmental semiconductor material, TiO2 has important applications in the fields of environmental protection and water treatment. The preparation of P25 particles into nano-functional material films with a high specific surface area has always been a bottleneck limiting its large-scale application. In this paper, a one-step method of preparing TiO2 nanocomposites by doping carbon nanotube (CNT) and carbon quantum dots (CQD) with tetrabutyltitanate and P25 TiO2 under ultrasonic radiation is proposed to synthesize a novel antifouling material, which both eliminates the bacterium of Escherichia coli and shows good photoelectric properties, indicating a great value for the industrial promotion of TiO2/CNT. This mesoporous composite exhibits a high specific surface area of 78.07 M2/g (BET) and a tested pore width range within 10–120 nm. The surface morphology of this composite is characterized by TEM and the microstructure is characterized through XRD. This preparation method can fabricate P25 particles into a nano-functional material film with a high specific surface area at a very low cost.

“…It has been reported in the literature that the combination of carbon materials and titanium dioxide can prepare excellent nanocomposite functional materials and exhibit various excellent properties. Especially in the fields of energy and environment, human beings urgently need to find sustainable energy materials and environmental governance materials [ 18 , 24 , 25 , 26 ]. However, the interfacial bonding performance of composite materials has always been a key factor affecting their development, and the composite interface of titanium dioxide and carbon materials in particular has always attracted the research of scientists.…”

TiO2 has attracted significant research interest, principally due to its nontoxicity, high stability, and abundance. Carbon-doped TiO2 can improve light absorption efficiency. In order to prepare high-efficiency photocatalysts, carbon-doped composites were prepared by hydrothermal reaction in a high-pressure reactor, and then TiO2/CNT mesoporous composites were prepared by the sol–gel method in an ultrasonic environment. Characterized by SEM and TEM, the composite materials contained TiO2 nanoparticles as well as CNT. After phase analysis, it was the anatase-doped phase. The following infrared light absorption performance and Escherichia coli bactericidal performance tests showed that it had better infrared and visible light absorption performance than pure TiO2. The TiO2/CNT mesoporous nanomaterials synthesized in this work are possible for clean industrial productions.
