Article Abstract
Porous anatase TiO(2) microspheres composed of {010}-faceted nanobelts were synthesized through simple thermal treatment of a titanium glycerolate precursor. The as-prepared TiO(2) nanomaterial was shown to serve as an efficient photocatalyst for H(2) evolution, and its activity was more than twice that of the benchmark P25 TiO(2).
Traditional wastewater treatment often fails to remove pharmaceuticals, necessitating advanced solutions, such as TiO photocatalysis, for post-treatment. However, conventionally applied powder TiO can be cumbersome to separate from treated water. To solve this issue, this study immobilized three TiO photocatalysts (Anatase 16, Anatase 5, and P25) into porous layers and evaluated their efficacy for the degradation of three pharmaceuticals (naproxen, NPX; sulfamethoxazole, SMX; metformin, MTF) in standard solutions and greywater pretreated in a membrane bioreactor (MBR).

Toxic heavy metal ions, such as lead ions, significantly threaten human health and the environment. This work introduces a novel method for the simple and sensitive detection of lead ions based on biochar-loaded titanium dioxide nanoparticles (BC@TiONPs) nanocomposites. Eco-friendly biochar samples were prepared from spent coffee grounds (500 °C, 1 h) that were chemically activated with TiO nanoparticles (150 °C, 24 h) to improve their conductivity.

Photocatalytic CO reduction is considered a sustainable method to address energy and environmental issues by converting CO into fuels and chemicals, yet the performance is still unsatisfactory. Single atom catalysts hold promising potential in photocatalysis, but the selection of metal species is still limited, especially in early transition metals. Herein, inspired by the structure of anatase TiO, single Ti sites were successfully incorporated into a metal hydroxide support for the first time cationic defects, significantly enhancing the photocatalytic performance by more than 30 times (from 0.
Volatile organic compounds (VOCs) are the main cause of environmental pollution and numerous respiratory diseases. Most VOCs molecules can be entirely converted into HO and CO by photocatalytic technology without the demand for additional oxidants, making it an ideal choice for air purification. However, for conventional photocatalysts, a smaller specific surface area is not conducive to enriching VOCs molecules on the surface of catalyst.
In recent years, slippery liquid-infused porous surfaces (SLIPSs) have gained significant attention in antifouling applications. However, their slippery performance often deteriorates in dynamic environments, limiting their service life. TC4 titanium alloy, commonly used in hulls and propellers, is prone to biofouling.
