“…The sintering under N 2 is to keep the bowl-shaped morphology as much as possible and prevent the PS-P4VP/TiO 2 microspheres from collapsing at high temperatures, while the air sintering is to better remove the PS-P4VP polymer residue. Due to the high electron-hole recombination rate of TiO 2 , the photocatalytic efficiency is low, and the wide band-gap makes the light response range of TiO 2 lower [ 34 ]. PS-P4VP nanoparticles can not only be used as a template for the formation of bowl-shaped TiO 2 but also introduced rich in C and N elements.…”

As implant substitutes are increasingly applied to the clinic, the infection caused by implants has become one of the most common complications, and the modification of the antibacterial function of the implant can reduce such complications. In this work, a well-defined bowl-shaped nanostructure coating with photocatalytic and photothermal synergistic antibacterial properties was prepared on Ti-19Zr-10Nb-1Fe (TZNF) alloy. The coating is obtained by spin-coating and sintering TiO2 precursors templated from self-assembled microspheres of polystyrene-poly(4-vinylpyridine) (PS-P4VP) amphiphilic block polymer (BCP) on TZNF alloy. PS-P4VP provides the bowl-shaped TiO2 nanostructures doped with C, N elements, reducing the bandgap of TiO2, which can absorb near-infrared (NIR) light to release reactive oxygen species (ROS) and produce photothermal conversion. The bowl structure is expected to enhance the utilization of light via the reflection in the confined space. The bowl-shaped surface has 100% antibacterial rates after 30 min of NIR light irradiation. In addition to antibacterial properties, the bowl-shaped surface has better hydrophilicity and protein adsorption capacity. The amount of protein adsorbed on TZNF with the bowl-shaped structures was 6 times that of TZNF. Hence, the bowl-shaped nanostructure can promote the proliferation and adhesion of osteoblasts, the cell proliferation rate was increased by 10-30%.

“…The hydrothermal method, also known as the hydrothermal synthesis method, is a primary method for preparing nano-TiO 2 materials. [98][99][100][101][102][103][104] This method usually uses an aqueous solution as the reaction medium in a closed container (autoclave) and adds TiO 2 precursor. After heating to the reaction temperature, the precursor is dissolved, nucleated, grown, and then washed and dried to obtain TiO 2 nanometers powder.…”

TiO 2 photocatalysis, as an energy-saving, highefficiency and green technology, has a wide range of applications in sewage treatment, cancer treatment, hydrogen production, photocatalytic CO 2 reduction and photocatalytic sensors. However, the large band width (E g = 3.2 eV) of TiO 2 material hinders its practical application, which in turn leads to low visible-light utilization and low quantum yield.Therefore, the preparation of TiO 2 with high quantum yield and fast response to visible light has become a key topic in current photocatalyst research. This review discusses different photocatalytic applications, current synthetic techniques for the elaboration of nanostructures of several TiO 2 -based materials and recent advances in enhancing visible photocatalytic activity.

“…It is probable to replace conventional fossil fuels with sustainable H 2 fuel. , It exhibits a high value of gravimetric energy in comparison to that of the gasoline (i.e., 120 MJ/kg versus 44 MJ/kg) . Its nature is storable and renewable, and no carbon emissions occur from its consumption. , The H 2 fuel can be generated through various means, including steam reforming/partial hydrocarbon oxidation, coal gasification, and water splitting. − The Earth’s surface is mainly covered with 71% of water, and the purest form of H 2 is produced from water splitting, which does not require high-temperature treatment. Thus, in order to reduce the anthropogenic CO 2 emission in the atmosphere, solar water splitting has been an essential factor. − …”

Photoelectrochemical (PEC) water splitting offers a sparkling and sustainable strategy for hydrogen generation, and significant research for enhancing the conversion efficiency of electrocatalysts is underway, since a huge number of publications have been reported in this field. Hence, it is urgent to write a comprehensive and updated review in order to highlight the latest progress in the design, fabrication, and modification of electrocatalysts for high-efficiency PEC water splitting. In this review, we describe the basic mechanism of PEC water splitting utilizing electrocatalysts in detail. Further, we highlighted the recent advancements in the design, fabrication, and modification of high-efficiency electrocatalysts for energy conversion. In addition, the catalysts' surface passivation, heterojunction constructions, defect engineering, and photovoltage and photocurrent enhancements are also highlighted.
