Constructing Polyphosphazene Microsphere-Supported Pd Nanocatalysts for Efficient Hydrogenation of Quinolines under Mild Conditions

Catalysts, Journal Year: 2024, Volume and Issue: 14(6), P. 345 - 345

Published: May 27, 2024

The efficient hydrogenation of N-heterocycles with H2 under mild conditions remains a significant challenge. In this work, polyphosphazene (PZs) microspheres, novel organic–inorganic hybrid materials possessing unique –P=N– structural units and diverse range side groups, were used to serve as support for the design stable Pd nanocatalyst (Pd/PZs). PZs microspheres prepared by self-assembly induced precipitation polymerization, nanoparticles grown loaded on chemical reduction process. Several characterization techniques, including XRD, FTIR, SEM, TEM, XPS, BET TGA, study features nanocomposites. results revealed that uniformly distributed primary sizes ranging from 4 9 nm based abundance functional P/N/O groups in PZs. Remarkably high catalytic activity stability observed quinoline compounds using Pd/PZs conditions. Rates 98.9% conversion 98.5% 1,2,3,4-tetrahydroquinoline selectivity could be achieved at low pressure (1.5 bar) temperature (40 °C). A possible reaction mechanism over was proposed. This work presents an innovative approach utilizing Pd-based highly multifunctional hydrogenation.

Catalysts, Journal Year: 2024, Volume and Issue: 14(8), P. 520 - 520

Published: Aug. 11, 2024

Peroxymonosulfate (PMS, SO52−)-based oxidation is an efficient pathway for degrading organic pollutants, but it still suffers from slow degradation efficiency and low PMS utilization. In this work, we report the preparation of porous Fe-doped g-C3N4 catalysts by one-step thermal polymerization using urea transition metal salts as precursors investigate effect atmosphere conditions (air nitrogen) on catalytic performance. Systematic characterizations show that prepared in air (FeNx-CNO) has a larger specific surface area (136.2 m2 g−1) more oxygen vacancies than N2 (FeNx-CNN, 74.2 g−1), giving active sites to participate reaction. Meanwhile, FeNx-CNO inhibits recombination photogenerated carriers improves light The redox cycling Fe(III) Fe(II) species photocatalytic system ensures continuous generation SO5•− SO4•−. Therefore, can remove CBZ up 96% within 20 min, which 3.4 times higher CNO 3.1 FeNx-CNN, retain 93% after 10 cycles This study provides economical method photocatalysis medicines contaminated water.
