| Ni(OH)2 and Co(OH)2 modified g-C3N4 for photocatalytic CO2 reduction | This study presents the synthesis and characterization of composite photocatalysts based on g- C 3 N 4 modified with Ni(OH) 2 and Co(OH) 2 for CO 2 reduction under visible light (λ = 410 nm). XRD, UV-Vis spectroscopy, and high-resolution TEM analyses revealed that the deposition of hydroxides did not disrupt the g-C 3 N 4 structure but caused a slight increase in the interlayer spacing and band gap; Ni(OH) 2 formed nanoparticles of ∼7 nm, whereas Co(OH) 2 crystallized as larger particles of ∼24 nm. TEM showed that after the photocatalytic CO 2 reduction, partial agglomeration of Ni(OH) 2 /NiO occurs. The catalyst containing 0.1 wt.% Ni(OH) 2 exhibited the highest activity – 7.04 μmol·g −1 ·h −1 , achieving a CO 2 reduction rate 1.9 times higher than that of pristine g-C 3 N 4 . The 0.5 wt.% Co(OH) 2 /g-C 3 N 4 photocatalyst was achieved a 1.3-fold increase in activity compared to pristine g-C 3 N 4 . This enhancement is attributed to the formation of a II type heterojunction between g-C 3 N 4 and Ni(OH) 2 , which facilitates charge transfer and suppresses recombination. | 10.17586/2220-8054-2026-17-1-81-89 | 04.03.2026 |

| Synthesis of 2-Arylpropionic Acids by Pd-Catalyzed Carbonylation of Vinyl Arenes with Formic Acid under Mild Reaction Conditions | Efficient synthesis of 2-arylpropionic acids by Pd-catalyzed carbonylation of vinyl arenes with CO and HCOOH is reported. Excellent regioselectivity to target 2-arylpropionic acids is achieved by the addition of some polyvinylpyrrolidone. Mild reaction conditions, available catalytic system and low Pd loading are the advantages of the proposed protocol. It was used in the total synthesis of rac-naproxen starting from commercially available 6-hydroxy-2-naphthoic acid. Additionally, vinyl acetate hydroxycarbonylation in 2-acetoxypropionic is demonstrated. | 10.7868/s3034630425070038 | 2025 |
| A Comparison of Catalytic Activity of Ammonium and Phosphonium Salts in Carboxylation of Epoxides Without Lewis Acids | A comparative analysis of the catalytic efficiency of various organocatalysts for the carboxylation of epoxides based on ammonium and phosphonium salts was carried out. The results show that among low molecular weight onium salts, the efficiency of epoxide carboxylation is influenced by both the structure of the catalyst and its solubility in the reaction medium. The best efficiency was achieved with tetrabutyl-substituted onium iodides and bromides. The addition of 20 mol.% water together with the onium salt significantly accelerates the reaction with epoxides and leads to quantitative yields of mono- and disubstituted cyclic carbonates. A polystyrene type catalyst modified with an immobilized tributylphosphonium group (cat. 4 mol.%) with an additive of 1 equiv. of water leads to a quantitative yield of butylene carbonate and can be recycled without loss of catalytic activity (tested for 10 cycles), which makes it promising for practical application. | 10.7868/s3034630425070096 | 2025 |
