Abstract
The present invention relates to novel poly(heptazine imides), a photocatalytic system comprising such poly(heptazine imides) and a sulfur source as well as the application thereof in photocatalytic reactions.
Claims54
A photocatalytic system comprising
- at least one poly(heptazine imide) and
- at least one sulfur source.
Compounds comprising repeating structural units of formula (I)
- wherein
- the arrows each denote a bond to a imide group (—NH—) through which two structural units of formula (I) are linked together or a bond to an end group.
- Mn+ denotes an n-valent cation with n being 1, 2 or 3 preferably 1 or 2 and more preferably 1
- q is 1/n
1 more element
Compounds prepared by a process comprising at least the steps of
- a) providing a mixture comprising lithium chloride, potassium chloride and 5-aminotetrazole
- b) heating the mixture provided in step a) to a temperature of 450° C. to 700° C., preferably 500° C. to 700° C., more preferably 500° C. to 650° C. and even more preferably 520 to 620° C., preferably for a duration of at least 60 minutes, preferably at least 2 hours and even more preferably at least 3 hours.
