Functional carbon fibers were prepared by carbonization of thermostabilized electrospun lignin-fibers at 500–900 °C followed by a high temperature thermal treatment at 1200–1600 °C. The effect of the preparation temperature ...

Catalytic dehydration of methanol on an acid carbon catalyst prepared by chemical activation of olive stone with H3PO4 is reported. This preparation methodology produces carbons with a well-developed porous texture and ...

Chemical activation with H3PO4 of lignocellulosic waste generated surface phosphorus functionalities with acid character (Rosas et al., 2009). These P groups also governed the carbon reactivity with oxygen, conferring ...
