INTRODUCTION
This article deals with multifunctional porous materials recently developed from plant resources. After a brief review of the industrial importance of porous materials, the benefits of designing them from wood and the various substances present in lignocellulosic biomass, we present highly porous foams and gels derived from tannin, lignin or cellulose. We then look at carbonaceous solids derived from foams and gels, as well as wood itself. Potential applications for these new materials are described, all linked to the two major fields of energy and the environment.
The present article deals with multifunctional porous materials recently developed from vegetable resources. After some brief reminders about the industrial importance of porous materials, the interest of preparing them from wood and other substances present in lignocellulosic biomass, highly porous foams and gels derived from tannin, lignin or cellulose are presented. The case of porous solids derived from foams and gels, and from wood itself as well, is treated next. Potential applications of all these new materials are described, all related to the key domains that are energy and environment.
