Abstract
The present invention relates to metal-organic frameworks (MOFs) which contain trimetallic centres with pyrazole as a ligand in the structure thereof. Particularly, it relates to MOFs which contain units of formula (I). The present invention also relates to a photocatalytic method for generating H2 starting from liquid water or vapour using said materials.
Claims9
A photocatalytic method for producing hydrogen starting from water comprising the use of a catalyst that is a metal organic framework characterized in that it comprises units of formula (I) in the structure thereof:
- wherein M1, M2 and M3 are metal cations selected from the list consisting of Co and Cu, wherein M1, M2 and M3 are equal to each other;
- X is a substituent selected from the list consisting of:
- H, CH3, OCH3, SO3−, F, Cl, Br, I, NH2, and CF3;
- Y is COO−;
- Z is a substituent selected from the list consisting of:
- H, CH3, OCH3, SO3−, F, Cl, Br, I, NH2, and CF3;
- L1, L2, L3 and L4 are groups independently selected from the list consisting of:
- O2−, OH−, H2O and halide;
- n1, n2, n3 and n4 are numbers independently selected from 0 and 1, and
- contacting the metal-organic framework, with water in liquid or vapor state and in the presence of sunlight or artificial light.
