Project Abstract:

The reduction of carbon dioxide has received a great deal of attention in recent years. With increasing concerns about rising atmospheric CO2 levels, scientists have discussed new strategies to reduce the impact of CO2 on global warming. Many ideas have involved trapping the “greenhouse gas” and converting it into fuels and organic materials, using either light or electrical energy. In this context, NANOPEC project aims the development of a continuous photoelectrochemical (PEC) device in two possible configurations (liquid or gas phase), able to simulate overall natural photosynthesis processes, in which the light-dependent stage is represented by the water oxidation taking place at the photoanode, while the secondary light-independent stage, the CO2 reduction, takes place at the dark counter electrode. Reaching the objectives of the proposal will open a wide field of investigation that goes far beyond questions of developmental of photocatalysis. The originality and innovative nature of the project lie in the link between chemical, physical and photo/electrochemical properties of the developed materials.

Project Objectives:

The NANOPEC project main objective is the development of PEC devices that simulate as closely as possible the natural photosynthethic processes taking place in leaf. To achieve this, the NANOPEC will be focused over three important aspects: i) The first one is the design and preparation of both types of electrodes in such way to maximize the potential of the used materials; ii) The second aspect refers to the testing of each PEC components and to optimize the photoelectrochemical parameters; iii) The last important aspect is the design of appropriate PEC devices by putting together the two developed PEC components.
Starting from the main objective, NANOPEC will consider the following derived objectives: i) Materials development and characterization, which include all the preparation and assembling steps of the PEC electrodes; ii) Development and optimization of individual PEC devices, which imply a correct evaluation of all engineering aspects in terms of reactor configuration, and iii) Proof-of-concept PEC devices.
