Systematic studies of tannin–formaldehyde aerogels: preparation and properties

Author(s): Alain Celzard, Andrzej Szczurek, Antonio Pizzi, Gisele Amaral-Labat, Vanessa Fierro

A variety of tannin-formaldehyde aerogels were produced in order to examine the effects of pH and dilution during their manufacture. The authors produced a phase diagram that could describe them. ...

One-pot synthesis, characterization and properties of acid-catalyzed resorcinol/formaldehyde cross-linked silica aerogels and their conversion to hierarchical porous carbon monoliths

Author(s): Ai Du, Bin Zhou, Guangming Wu, Jun Shen, Ke Chen, Xiurong Zhu, Zhihao Bao, Zhihua Zhang

Aerogels are ultra-light, insulative, porous materials that have a wide variety of applications. The aim of this study was to synthesize resorcinol/formaldehyde (RF) cross-linked silica aerogels in one pot ...

Biomass-derived, thermally conducting, carbon foams for seasonal thermal storage

Author(s): Alain Celzard, Antonio Pizzi, P. Jana, V. Fierro

Seasonal thermal storage based on phase change materials (PCMs) require a thermally conductive host because they typically have low thermal conductivities. In this study, tannin-based composite carbon foams were prepared ...

New tannin-lignin aerogels

Author(s): A. Szczurek, Alain Celzard, Antonio Pizzi, B. N. Kuznetsov, G. Amaral-Labat, L. I. Grishechko, V. Fierro

Tannin and lignin are organic materials that are more cost-effective than synthetic, non-renewable phenolic compounds. In this paper, tannin-lignin-formaldehyde (TLF) composites were used to synthesize thermally insulative mesoporous aerogels. A ...
