Reply to comment by SOwED in Scientists have shown how toxic dyes can be filtered out of wastewater using the method and material developed by the group. The procedure uses sunlight as a catalyst and doesn’t involve any pressure or heat. It can remove 80 percent of dye pollutants in wastewater. by Wagamaga
I was thinking that, presumably they mean that sunlight provides activation energy for a reaction.

Exactly. Unlike a catalyst which lowers the required activation energy but doesn't actually provide any energy itself.
