Due to the presence of exchangeable protons in the framework of TiP and Ti-ATMP materials, they can act as solid acid catalysts and hence an attempt has been made for the catalyzed synthesis of dihydropyrimidinones (DHPMs) using these materials. The effects of reaction time, temperature, catalyst concentration and substituents on DHPMs synthesis have been studied. Further, the reaction is carried out in various solvents and under solvent free conditions in order to evaluate the feasibility of developed protocol to be used under diverse chemical environment. The isolated DHPM products were characterized based on their physical melting point (M.P.), FT-IR, ¹H and ¹³C NMR spectroscopy.

In the present study, we focused on obtaining a sonophotosensitizer with high therapeutic efficacy for sonophotodynamic therapy (SPDT). For this purpose, zinc phthalocyanine bearing pyridine derivative groups (2) and its water-soluble cationic derivative (3) were synthesized, and their singlet oxygen generating capacities were evaluated using both light (photochemical method) and light and sound combination (sonophotochemical method) as excitation sources for phthalocyanines 2 and 3 in DMSO and aqueous solution, respectively. The singlet oxygen quantum yields of the complexes upon photochemical excitation were calculated as 0.79 for 2, 0.68 for 3 in DMSO and 0.31 for 3 in aqueous solution. Sonophotochemical excitation increased the singlet oxygen quantum yields of the complexes by 38% for 2 and 48% for 3, particularly in DMSO. These results revealed that the synthesized sensitizers exhibited exceptional efficiency in the production of singlet oxygen, a critical reactive oxygen species required for efficient cancer cell destruction.

Herein, a series of mesoporous nitrogen-rich carbon nitride (mpg-CN) materials were synthesized using 5-amino-1<i>H</i>-tetrazole as a precursor via a hard-templating method. The synthesized mpg-CN, specially prepared under lower carbonization temperatures had higher nitrogen contents (C₃N₇, C₃N₆, and C₃N₅) than the ordinary carbon nitride (C₃N₄). The surface areas and distributions of nitrogen species were dependent on the carbonization temperatures. As metal-free solid bases, mpg-CN exhibited high activity in Knoevenagel condensation reactions. The mpg-C₃N₆ material showed the highest activity, achieving a benzaldehyde conversion of 80.6% and selectivity to the target product of 99.2%, attributed to its higher fraction of pyrrolic nitrogen species.

While various catalysts have been employed in CO catalytic converters, noble metal catalysts remain prohibitively expensive and scarce. Additionally, non-noble metal catalysts often exhibit suboptimal activity and weak long-term stability. To address these challenges, a promising approach involves supporting catalytically active materials on porous oxide layers with strong adhesion to metallic substrates. Plasma electrolytic oxidation (PEO) emerges as a viable, straightforward, and rapid coating technique for creating highly adherent, ceramic-like porous oxide layers. PEO coatings can serve as superior catalyst supports, enabling the deposition of highly active and stable catalysts for CO oxidation reactions.
