In the 2019 Climate Action Summit, the UN members states have committed to limit global warming to 1.5\u00b0C versus pre-industrial\u00a0levels. This implies reducing greenhouse gas emissions by 80 to 95 % of the 1990 level by 2050. As a result of this ambitious\u00a0global challenge, hydrogen has rapidly become a key priority worldwide: see e.g. the European Green Deal, Europe\u2019s clean energy\u00a0transition and the Agenda – SRIA (Clean Hydrogen for Europe, July 2020). In this scenario, the SPHERA<\/strong> project investigates an\u00a0innovative, unique, and smart platform to produce green H2. The main project concept is based on combining ultrasound power with\u00a0heterogeneous photocatalysis in a single process unit powered only by renewable energy. In this regard, SPHERA<\/strong> will explore the\u00a0potential of ultrasound technologies to engender hydrogen by mechanical stimulation of water using ultrasonic waves (20\u20131000kHz)\u00a0and to address the main critical issues of photocatalysis pathway, represented by the lack of solar sensitivity and lower efficiency,\u00a0especially in terms of H2 production. To this purpose, SPHERA<\/strong> will study original synergistic intensification routes to develop a new\u00a0generation of hybrid sono-photocatalitic reactors characterized by the integration of ultrasonic irradiation, ultraviolet\/visible radiation\u00a0(UV\/VIS-light) and a photocatalyst, based on the following rationale: 1) the hybrid action of ultrasound waves and UV\/VIS-light\u00a0 improves the synergistic effect of hydrogen production compared to the single photocatalysis pathway reducing the rate-limiting\u00a0step and increasing the magnitude of the associated kinetic; 2) the ultrasound irradiation enhances photoactivity of the employed\u00a0material through the augmentation of the active surface area and the charge separation, which enhances the mass transfer of\u00a0hydrogen from the surface of the catalyst to the bulk, and provokes the detachment of hydrogen bubbles from the catalyst surface;
3) the intelligent automatic and fine control of process parameters increase the efficiency of the overall process including\u00a0energy-saving; 4) the use of ultrasonic waves irradiation during photocatalyst preparation improves its morphology, specific surface\u00a0area, particles size distribution, dispersion of active sites and consequently, the photocatalytic activity. To achieve its goals, SPHERA\u00a0will follow a multidisciplinary approach combining model-based design with lab- and bench-scale experimentation to identify the\u00a0optimal reactor design. The ultimate project target is the comparative evaluation of the investigated process configurations from the\u00a0energetic, economic and environmental standpoints.
