| OBSERVATION'S |
The prospect of using solar energy to convert water into H & O has received a boost with the discovery of new class of semiconducting photocatalysts highly efficient at splitting water under UV irradiation. Quantum yields of up to 23% can be achieved. The group showed that the highest rates of water splitting occur when the materials are loaded with 1% of Ni |
| SYNTHESIS |
The new catalysts were prepd from materials known as layered perovskites. The perovskite materials have generic compn - (Ca)m(Nb)m(O)3m+2; m = 4 or 5 Perovskite powders impregnated with Ni |
