[International Journal of Hydrogen Energy]Composite membranes based on polybenzimidazole and ionic liquid functional Si-O-Si network for HT-PEMFC applications
Polybenzimidazole (PBI)/ionic liquid (IL) functional Si–O–Si network composite membranes are prepared from PBI with 1-(3-trimethoxysilylpropyl)-3-methylimidazolium chloride. The IL can be hydrolyzed to form Si–O–Si network structure under acidic conditions. And such IL functional Si–O–Si network (NP) in the composite membranes could improve phosphoric acid doping levels andproton conductiv...

[Journal of Membrane Science]Polybenzimidazole/ionic-liquid-functional silica composite membranes with improved proton conductivity for high temperature proton exchange membrane fuel cells
A series of polybenzimidazole containing hydroxyl groups (PBIOH)/ionic-liquid-functional silica (ILS) composite membranes (PBIOH-ILS) have been successfully prepared for the high temperature proton exchange membrane fuel cells (HT-PEMFCs). These ionic-liquid-functional silica (ILS) nanoparticles, which germinate from the polymer chains by an in situ sol-gel reaction, enhance the performance of p...

【64 Applied Materials Today】 Main-chain poly(ionic liquid)-derived nitrogen-doped micro/mesoporous carbons for CO2 capture and selective aerobic oxidation of alcohols
Sustainable development and the recent fast-growing global demands for energy and functional chemicals urgently call for effective methods for CO2 remediation and efficient metal-free catalysts for selective oxidation of aromatic alcohol. Herein, a unique main-chain poly(ionic liquid) (PIL) is employed as the precursor to prepare nitrogen-doped micro/mesoporous carbons via simultaneous carbonizati...

【66 Angewandte Chemie International Edition】 Poly(ionic liquid)-derived carbon with site-specific N-doping and biphasic heterojunction for enhanced CO2 capture and sensing
CO2 capture is a pressing global environmental issue that drives scientists to develop creative strategies for tackling this challenge. The concept in this contribution is to produce site‐specific nitrogen doping in microporous carbon fibers. Following this approach a carbon/carbon heterojunction is created by using a poly(ionic liquid) (PIL) as a “soft” activation agent that deposits nitrogen ...
