Key Highlights
•
A new chemical bridge using a molecule called Me-TACl creates a strong link between 2D and 3D perovskite layers in solar cells. This one-step solution simultaneously builds a stable 2D top layer and a robust interface, leading to highly efficient and flexible solar cells that are also more durable.

Researchers have mapped out how titanium dioxide (TiO2) photoanodes, a key material for splitting water into hydrogen and oxygen using sunlight, degrade under different conditions. In acidic water, corrosion stops once the material saturates, but in alkaline water, a messy redeposition of degraded material clogs the surface and kills performance.

This review explains that positively charged ions (cations) in the electrolyte are not just spectators but active players in turning CO2 into fuels using electricity. They can change the local environment, tweak the energy needed for reactions, and even help shuttle electrons, which is crucial for designing better and more selective catalysts.
