The use of solar energy to driven the chemical and energy processes, and the chemical storage of solar energy are crucial aspects to move to a low-carbon economy, sustainable society and to foster transition in energy and chemistry. There is a fast-growing scientific interest on this subject, with emerging new directions and applications also at industrial level. Realize this challenge requires the development of new ideas, concepts and innovative photocatalytic materials. Photocatalysts are widely utilized to clean and remediate our environment and their use in advanced devices to produce electrical energy or solar fuels in rapidly expanding. Semiconducting photocatalytic materials possess multi-functional properties, which allow their use in various areas from photocatalytic environmental remediation, water splitting for hydrogen fuel, CO2 reduction, self-cleaning coatings, electrochromic devices and sensors, and low cost solar cells. New emerging area will include the development of new technologies to convert small molecules such as O2, N2 and CH4, and the coupling between photocatalysis and non-thermal plasma chemistry. The nano-architecture design of these materials is of crucial relevance to achieve these different functional characteristics and realize an efficient energy conversion. There is the need to gather together multiple competences to accelerate the development of these nanomaterials for solar energy and environmental applications.         
This Symposium aims to provide a multi-disciplinary forum for scientists, engineers and industry experts to break new ground in the discussion, and realize a cross fertilization and progress in the understanding of the design criteria for their use. Among the recent developments that will be highlighted in the symposium are advances in synthesis of novel materials with tailored nano-architecture; the preparation of thin films and nanostructures; the advanced characterization by experimental and theoretical methods of these materials and of their structure-performance relationships; processing techniques, device fabrication and stability; advances in environmental applications and in air quality improvement; novel concepts, technologies and materials for photocatalysis.
