个人简介

Eric Prouzet carries out research in material chemistry and nanotechnology. His research is focused on the synthesis of nanostructured materials such as porous materials and nano-objects. His main domain of research is using soft matter such as micelles, liquid crystals and biogels, as adaptive soft templates or molds. He has great expertise in particle and porosity size analysis, and created the Waterloo Structure Analytical Platform (WatSAP) that offers up-to-date equipment for these analyses. His research has applications in a range of areas including membrane processes, catalysis, photovoltaic or magnetic devices. Eric is also highly committed to innovation, including teaching, scientific consulting for two startups, and co-founder of two companies, one in biotechnologies (industrial production of microalgae), and one in IT (document search engine).

研究领域

Eric Prouzet has developed a specific method for the preparation of mesoporous silica with a good control over the pore size in the range 2 – 9 nm and a narrow pore size distribution. These objects are perfect nanobricks that allow him to build porous bodies where the porosity is created by the assembly of surfactants and the walls by condensation of silica oligomers. His current research in this domain aims to offer a sustainable easily scaled-up industrial process, where organic templates used for the synthesis can be recovered and reused. Eric also develops ceramic membranes for both liquid and gas separation in place of energetic processes (distillation, cryogenic processes). Among the most promising fields are sea water desalination for production of fresh water, hydrogen production for fuel cells, and CO2 recovery from fossil fuel power plants. In another nano research area, Eric specializes in porous matrixes that can be used as molds for the generation of nanoparticles in a confined environment. He uses the dynamics of soft matter to define specific molds that allows him to shape materials synthesised within.

Professor Prouzet research interests include the synthesis of porous materials and nano-objects with the help of soft matter (micelles, liquid crystals, biogels) with applications in various domains (membrane processes, catalysis, organic or inorganic nanoparticles). We have developed a specific method for the preparation of mesoporous silica with a good control over the pore size in the range 2 – 9 nm and a narrow pore size distribution. These objects are perfect nanobricks that allow us to build porous bodies where the porosity is created by the assembly of surfactants and the walls by condensation of silica oligomers. We develop ceramic membranes for both liquid and gas separation in place of energetic processes (distillation, cryogenic processes). Among the most promising fields are sea water desalination for production of fresh water or hydrogen production for fuel cell or CO2 recovery from fossil fuel power plants. Compared with polymer membranes, ceramic membranes offer a better durability and a higher resistance to temperature or corrosive environments. We explore how using commercial nanopowders as starting materials could allow us to build the actual filtration layer (on commercial ceramic supports) with a lower cost. The method that is currently under study is based on a sol-gel based process for achieving the partial densification between nanoparticles. In another nano research area, we specialize in porous matrixes that can be used as molds for the generation of nanoparticles in a confined environment. We used the dynamics of soft matter to define specific moulds that allow us to shape materials synthesised within. We illustrate this method by the synthesis of nanoslabs of Polypyrrole (pPy). The lamellar shape of these nanoslabs (200 nm size) allowed us to create pPy electrodes on plastic films by simple deposition (collaboration with Prof. Leung, University of Waterloo, Waterloo Advanced Technology Laboratory (WATLab)) and they will be studied as additional matrix for the preparation of thermoelectrical nanocomposites (collaboration with Prof. Kleinke, University of Waterloo, Chemistry). These nanoslabs can be also combined with other nanomaterials like carbon nanotubes and lead to nanocomposite structures that could be good candidates for electrodes in lithium-air batteries. CO2 recovery must proceed in a way that high purity CO2 can be recovered, which would facilitate its further storage. We built a project with several companies (4) and universities (3: France, Norway, Canada) to develop a platform that could extract CO2 by combining both innovative membranes (devoted to enrich the permeate gas in CO2) and high temperature adsorbents (for trapping reversibly pure CO2). The group is also involved as a main investigator in an Integrated European Program called NanoGLOWA. This program includes 26 partners and intends to provide technological solutions for CO2 trapping from power plants through membranes processes.
