It is our great pleasure to welcome you to the SPEA13.

Through plenary and keynote lectures, oral presentations, poster talks and poster sessions, the ambition of the five-day SPEA13 conference is to report on the most advanced research progresses in environmental photocatalysis and photochemistry, and to pave the way for future research and challenges.

SPEA13 will cover research fields as varied as water and air treatment/disinfection, novel materials and processes for solar photocatalysis, environmental photochemistry, hydrogen production and carbon dioxide utilization, functionalized surfaces, modelling and mechanistic studies, commercial applications and standardization, whether the research approach is fundamental or applied.

We truly hope that the SPEA13 program will reflect the high commitment and exceptional profile of the international community working in this field, and selected papers will be published in high impact factor journals following the SPEA meeting.Further information will follow on the website concerning key dates, travel advice, accommodation, social programme and touristic activities.

We are very much looking forward to welcome you to our beautiful city of Kraków!

On behalf of the Organizing and Scientific Committees,
