Ordered mesoporous carbons obtained from low-value coal tar products for electrochemical energy storage and water remediation

Ordered mesoporous carbons (OMCs) obtained by the hard-templating method are usually prepared using complicated infiltration procedures and/or relatively high-priced carbon precursors. In this work, OMCs were obtained using creosote, a modestly priced substance obtained from the distillation of coal...
