TiO2 composites with zeolite templated carbon (TiO2-ZTC) and activated carbon (TiO2-AC) were prepared and used as the photocatalysts for comparative studies with pure TiO2. TiO2-ZTC exhibited the highest rate of methylene blue degradation with a rate approximately 4 and 400 times higher than those of TiO2-AC and pure TiO2, respectively. Moreover, the highest catalytic performance of TiO2-ZTC in gas-phase degradation of acetone was approximately 1.1 and 12.9 times higher than TiO2-AC and pure TiO2, respectively. These outstanding performances could be attributed to high surface area, pore volume, and hydrophobic surface properties, leading to improvement in the adsorption properties of organic molecules.

Water purification has always been a critical yet challenging issue. In this study, an organic-inorganic composite membrane was developed using 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-oxidized bacterial cellulose (BC) nanofibers and hydroxyapatite nanowires (HAPNW) with tunable wettability for advanced membrane separation applications. The resulting free-standing TEMPO-BC/HAPNW filter membrane exhibited strong mechanical strength, high flexibility, exceptional deformability, and a high pure water flux of up to 800 L·m·h due to its porous architecture and inherent hydrophilicity.

Currently, there is great demand for flexible three-dimensional (3D) printable thermoplastic polyurethane (TPU) wires with excellent ultraviolet (UV) resistance, which have broad application prospects in wearable products. In this study, UV-resistant TPU composites were obtained using a blending modification method. The relationship between the optimized parameters of fused deposition modeling 3D printing and mechanical properties of the TPU composite is discussed using an orthogonal test.

Fluorescence spectroscopy employed to compute the antibacterial potential of pure ZnO and Titania (TiO) loaded ZnO (TiO: 2%, 4%, 6%, and 8%) electrospun nanofibers. The study of electrospun nanofibers followed by their structural, morphological and antibacterial properties has been revealed through fluorescence spectroscopy. X-ray diffraction (XRD) analysis of nanofibers calcinated at 600 °C revealed the presence of polycrystalline wurtzite hexagonal crystallographic planes of ZnO with preferred orientation along (101) direction.

A high recombination rate is a major limiting factor in photocatalysis. Mitigating recombination through material engineering and photocatalyst optimization is key to enhancing photocatalytic performance. In this study, a heterostructure MoS/CdS nanocomposite was synthesized through a hydrothermal method in a Teflon-lined autoclave subjected to a temperature of 200 °C for 16 hours.
