Developing efficient, stable, and cost-effective catalytic systems for renewable energy conversion and storage represents one of today's critical scientific challenges. In our research, we try to address these challenges through new approaches to photocatalysis, photoelectrochemical and electro-chemical systems.

The first part of this talk presents new approaches for growing polymeric carbon nitride (CN) layers on conductive substrates for photoelectrochemical applications. We demonstrate CN-based photoanodes as stable, efficient platforms for converting organic molecules into value-added chemicals while simultaneously producing hydrogen. In addition, I will show the use of CN-films as highly stable photocatalytic panels for various catalytic reactions.

The second part will focus on the rational synthesis of transition metals and their composites for various electro-oxidation and reduction reactions, including oxidative upgrading of organic mole-cules and hydrogen peroxide synthesis. I will present our recent work in zinc-air batteries, perox-ide-based electrolyzers, and alkaline water electrolyzers.
