What is it about?
Silicon is by far the most commercialized semiconductor in solar energy applications. However, the application of silicon in severe conditions (i.e., gas generation, acidic conditions, high I-V, etc.) generates an oxide layer on the surface which impedes further use. This work developed and optimized a protection/Co-catalyst layer for photocatalytic hydrogen generation reaction (HER).

Why is it important?
The first report of CoTe2 catalytic properties for HER is shown in this work.
