Abstract

International audience; Nanostructured silicon carbide (SiC) is an exceptional material with numerous applications e.g. in catalysis, biomedicine, high performance composites, and sensing. In this study, a fast and scalable method of producing nanostructured SiC from plant materials by magnesiothermic reduction via self-propagating high-temperature synthesis (SHS) route was developed. The produced biogenic material possessed a high surface area above 200 m 2 /g with a SiC crystallite size below 10 nm, which has not been done previously by SHS. This method enables affordable synthesis of the material plant-based precursors in a reaction that only takes a few seconds, thereby paving a way for nanostructured silicon carbide production in high volumes using renewable resources. The material was also functionalized with carboxylic acid and bisphosphonate moieties, and its use as metal adsorbent in applications such as wastewater remediation was demonstrated.

Abstract

Nanostructured silicon carbide (SiC) is an exceptional material with numerous applications, for example, in catalysis, biomedicine, high‐performance composites, and sensing. In this study, a fast and scalable method of producing nanostructured SiC from plant materials by magnesiothermic reduction via self‐propagating high‐temperature synthesis (SHS) route was developed. The produced biogenic material possessed a high surface area above 200 m2/g with a SiC crystallite size below 10 nm, which has not been done previously by SHS. This method enables affordable synthesis of the material plant‐based precursors in a reaction that only takes a few seconds, thereby paving a way for nanostructured SiC production in high volumes using renewable resources. The material was also functionalized with carboxylic acid and bisphosphonate moieties, and its use as metal adsorbent in applications such as wastewater remediation was demonstrated.

Abstract

Abstract: Binderless beta zeolite has been anchored on a silicon carbide foam with a monolithic shape. The catalytic activity of the resulting composite was evaluated for a Friedel–Crafts reaction carried out in a fixed-bed configuration: the benzoylation of anisole to p-methoxybenzophenone. The results obtained were compared with those of a commercial beta zeolite. Significantly higher product yields along with a stable activity were obtained with the BEA/SiC composite. It has been suggested that the opened structure of the β-SiC foam and the absence of any binder allow a fast desorption of the p-ketone which is the main product of the reaction but also the major source of deactivation due to strong adsorption and/or coke formation inside the microporosity of the zeolite.
