Question

Photocatalytic hydrogen generation from hydriodic acid using methylammonium lead iodide in dynamic equilibrium with aqueous solution

Answer 1

The solar-driven splitting of hydrohalic acids (HX) is an important and fast growing research direction for H 2 production. In addition to the hydrogen, the resulting chemicals (X 2/X 3−) can be used to propagate a continuous process in a closed cycle and are themselves useful products.
