Polypyrrole/TiO2 nanotube arrays with coaxial heterogeneous structure as sulfur hosts for lithium sulfur batteries (2016)
Journal Article

The lithium-sulfur cell has shown great prospects for future energy conversion and storage systems due to the high theoretical specific capacity of sulfur, 1675 mAh g?1. However, it has been hindered by rapid capacity decay and low energy efficiency....

Nitrogen-doped graphene guided formation of monodisperse microspheres of LiFePO4 nanoplates as the positive electrode material of lithium-ion batteries (2016)
Journal Article

Three-dimensional porous composite microspheres of LiFePO4 and nitrogen doped graphene have been synthesized by a solvothermal process coupled with subsequent calcination. The morphologies and microstructures of the composites are investigated by sca...

Esterification of fatty acids from waste cooking oil to biodiesel over a sulfonated resin/PVA composite (2016)
Journal Article

Sulfonated cation exchange resins (s-CERs) have been widely studied as a replacement of liquid acids for the catalysis of esterification of free fatty acids (FFAs) to produce biodiesel with water as the only by-product. However, the water produced ha... Read More about Esterification of fatty acids from waste cooking oil to biodiesel over a sulfonated resin/PVA composite.

More sustainable electricity generation in hot and dry fuel cells with a novel hybrid membrane of Nafion/nano-silica/hydroxyl ionic liquid (2016)
Journal Article

A new hybrid proton exchange membrane (PEM) has been prepared from hydroxyl functionalized imidazolium ionic liquid (IL-OH), Nafion and nano-SiO2. The IL-OH, with a hydroxyl group that acts as both a proton acceptor and donor, forms strong hydrogen b...

Preparation and characterization of a sulfonated carbon-based solid acid microspheric material (SCSAM) and its use for the esterification of oleic acid with methanol (2016)
Journal Article

In this study, a sulfonated group (-SO3H) rich carbon-based solid acid microspheric material was prepared by hydrothermal method followed by sulfonation using glucose as the raw material. Such a green, non-corrosive, and renewable carbon material was...
