The aim of the postdoctoral project is to synthesize hybrid heterojunctions and plasmonic composites under the framework of the development of advanced composites towards the photocatalytic CO2 reduction to ethylene (C2H4). The general objective is to reach 90% photon absorption and 80% chemical conversion into products, i.e. an overall photon to product efficiency of 70%.


The rational design strategy for optimization of the intimate contact between the different components of the composite photocatalysts consists in two approaches. On on hand, organic and inorganic semiconductors (SCs), medium band gap mostly, will be coupled in staggered heterojunction by using different synthetic methods (hydrothermal, sol-gel, impregnation, etc.) to allow a Z-scheme formation. On the other hand, monometallic and bimetallic nanoparticles (NPs) deposition onto previous optimized heterojunctions will be used to form Schottky junctions by using plasmonic metals to improve light harvesting yields of the system.
Selected performing semiconductors and metallic nanoparticles will allow creating a series of new composites to be evaluated towards photocatalytic CO2 reduction in gas phase, although liquid phase can be considered to be performed by partners of the project. Parametric studies to find optimized ratios of SCs and metal NPs loadings will take place. In order to understand the physico- chemical properties, a competitive state-of-the-art core is available at ICPEES Institute comprising characterization techniques to obtain morphological (HRTEM and SEM), structural (XRD), optical (UV-vis spectroscopy), electronic (UPS and EDX), surface (XPS, BET, zeta potential), thermal (TGA), chemical (FT-NIR, Raman, EPR spectroscopies and ICP-AES). Also, complementary charge carrier dynamics analysis by employing TRMC are expected at University of Paris Saclay. The objective is to bring mechanistic insights of the most performing composites and to correlate structure-activity aspects.
