Functional catalytic membrane development: A review of catalyst coating techniques.

Covalent organic frameworks (COFs) have emerged as an excellent support for heterogeneous catalysis due to their regular pore structure and high specific surface area. Herein, a series of porous Tp...

Pd Nanoparticles Loaded on Two-Dimensional Covalent Organic Frameworks with Enhanced Catalytic Performance for Phenol Hydrogenation

Catalytic nanofiber composite membrane by combining electrospinning precursor seeding and flowing synthesis for immobilizing ZIF-8 derived Ag nanoparticles

With the PTFE membrane as the substrate, a novel Ag-based catalytic membrane reactor (CMR) was fabricated by deep-permeation synthesis fabrication (DPSF). In DPSF, ZIF-8 was first assembled inside ...

Catalytic Membrane Reactor of Nano (Ag+ZIF-8)@Poly(tetrafluoroethylene) Built by Deep-Permeation Synthesis Fabrication

Here, we report on a green and effective method for the continuous and complete conversion of high concentrations of p-nitrophenol (PNP) using a flow-through membrane reactor and less NaBH4 The catalytic membrane was successfully fabricated by loading Pd nanoparticles onto the surface of a branched TiO2 nanorod-functionalized ceramic membrane The modification with branched TiO2 nanorods can significantly improve the loading amount of Pd nanoparticles onto ceramic membranes, resulting in enhanced catalytic performance With 6 mg of Pd, 93 L m−2 hr−1 of flux density and 804 cm2 of membrane surface area in the flow-through membrane reactor, PNP at a concentration of 4,000 ppm can be converted to high-value p-aminophenol using less NaBH4 (using a molar ratio of NaBH4:PNP of 96) within 24 s at 30°C More importantly, the conversion can be continuously and stably performed for 240 min

Continuous and complete conversion of high concentration p-nitrophenol in a flow-through membrane reactor

Atomic layer deposition (ALD) was adopted for the first time to load Pd nanoparticles on Al2O3 ceramic membranes (CMs) for fabricating catalytic membranes (Pd/CMs). The membrane surface was functio...
