Article Abstract
The catalytic activity of titanium silicalite-1 (TS-1) in cyclohexanone ammoximation is controlled by the intracrystalline diffusion limitations due to the hydrogen-bonding interactions between the internal Si-OH groups in TS-1 and HO, NH, and NHOH, while these Si-OH groups can be effectively annealed by an ultraviolet-assisted heat post-treatment, resulting in enhanced activity.

The abundant Si-OH groups serving as the defect sites in the ZSM-22 zeolite framework are not only closely associated with physicochemical properties and catalytic performance but are also the primary sites for attack by water molecules, thereby restricting applications involving or producing water. In the present study, a liquid-mediated healing process was used to convert the Si-OH groups in ZSM-22 zeolite into Si-O-Si bonds. The systematic investigation of the treatment solution's composition and the hydrothermal conditions revealed that the crystallinity of ZSM-22 zeolite can be effectively enhanced following optimal healing treatment.

Area-selective atomic layer deposition (ALD) has gained widespread interest in the semiconductor industry to facilitate the continued drive for more powerful and efficient devices. In this work, we chemically passivate SiO with a single SF/H/Ar plasma pretreatment to selectively deposit TiO on ZnO, HfO, or AlO, using tetrakis-(dimethylamido)-titanium (TDMAT) and HO. The SF/(H + SF) flow ratio was tuned to suppress the etching of SiO while the nucleation delay of TiO ALD was maximized.

Phase transition temperatures of pure water and aqueous sodium chloride (NaCl) solutions, both in bulk form and mixed with the silica (SiO) powder, were investigated using in-situ Raman spectroscopy. To determine the freezing and melting temperatures, the OH-stretching and bending regions of the Raman spectrum were analysed, along with investigation of hydrohalite (HH) formation in saline water. A spectral phase transition marker, S, defined as the intensity ratio of asymmetric to symmetric OH-stretching bands (I/I), was applied to measure the freezing and melting temperatures.

The increasing use and improper disposal of pharmaceuticals have caused significant environmental impacts. Conventional treatment methods face challenges at the industrial scale, whereas abundant, low-cost adsorbents such as residues offer a sustainable alternative for pharmaceutical removal. In this study, an adsorbent was developed from sludge generated by the water treatment system of a thermoelectric power plant.

Propane dehydrogenation (PDH) is a critical technology for propylene production, yet overcoming the trade-off between activity and stability remains a major challenge. Here, we engineer a robust Pt@Sn-MFI catalyst with a wormhole-type structure, featuring highly dispersed Pt clusters robustly anchored by open sites in Sn-MFI, i.e.
