Right now, I made oxides, which means that I mix metals on the first row of transitions metals in the periodic table (Fe, Ni, Co, Mn, Cu, Zn) between them and make a compound which also includes oxygen. They can absorb light that then I use to split water.
However, before my actual project, I used to work with novel metals like Pt, Pd, Au…to be use in “fuel cells”, so they will help to put hydrogen and oxygen back together and make energy
