Article Abstract

We report the novel synthesis of nanoporous TiO2 nanoparticle ensembles with unique mesoscale morphologies. Constituent nanoparticles evolved into multifaceted assemblies, exhibiting excellent crystallinity and enhanced photocatalytic activity compared with commercial TiO2. Such materials could be exploited for applications, like organic pollutant degradation.

Photoelectrochemical (PEC) water splitting offers a sustainable pathway for solar-to-chemical energy conversion, yet its efficiency is often limited by sluggish water oxidation and the generation of low-value oxygen. Here, the use of engineered titania nanopore (TNP) films is reported, fabricated via anodization and thermal annealing, as co-catalyst-free photoanodes for coupling hydrogen evolution reaction (HER) with polyethylene terephthalate (PET) reformation into high-value formate. By tuning the crystallographic phase of TiO from amorphous to anatase and rutile, the optimized anatase-phase electrode exhibits excellent PEC performance in a two-electrode configuration, achieving a high steady-state photocurrent density of [2.

Studying the electrophysical properties and conduction mechanisms of Au/TiO/Ti memristive structures based on nanoporous and nanotubular layers made of anodized titanium dioxide contributes to the improvement of quality indicators of prospective elements and nano-electronic devices derived from them. The paper measures the current-voltage characteristics and temperature dependencies of conductance in high-(HRS) and low-resistance states (LRS) for Au/TiO/Ti memristors with different thickness of nanoporous/nanotubular active layer. The importance of forming a nanotubular structure of the oxide layer with a thickness of 155-200 nm and an internal diameter of nanotubes of 21 ± 4 nm for improving the main characteristics of Au/TiO/Ti memristors when realizing the filamentary mechanism of resistive switching with the participation of oxygen vacancies is shown.

This research focuses on the synthesis of a novel low-cost, environmentally friendly, and recyclable Nano-porous ceramic using natural clay and cassava starch by the gelcasting method, which is then used as a TiO catalyst support. TiO Nano-porous ceramics synthesized using various amounts of cassava starch (4 %, 6 %, and 8 %), and impregnation by TiO was performed at various calcination temperatures (500 °C, 800 °C, and 1100 °C). X-Ray diffraction spectra were used for the analysis of structural properties, Fourier transform infrared (FTIR) spectra for the analysis of bonding characteristics and scanning electron microscopy image for the surface Nano-porous structure.

SiO aerogels have garnered significant attention for thermal insulation applications due to their exceptional hydrophobicity and thermal resistance. However, the organic functional groups enabling hydrophobicity introduce flammability concerns, limiting their safe implementation in high-temperature environments. This study presents a novel TiO doping strategy (SA/TiO) that simultaneously enhances thermal safety while preserving the material's intrinsic advantages.

This study develops a highly densified bronze-type TiO₂ (TiO(B)) anode to enhance the volumetric energy and power density of supercapacitors. By integrating ultracentrifugation with strategic carbon reduction via annealing, a TiO₂(B) anode with fluid-like lubrication, high compressibility, and improved electrode density is synthesized. The annealing process facilitated a hierarchical nanoporous TiO₂(B) network while preventing agglomeration, achieving an electrode density of 2.
