A plasmonic antenna-reactor photocatalyst is a photocatalyst that combines a catalyst with attached antenna that increases the catalyst's ability to absorb light, thereby increasing its efficiency.
A Silicon dioxide| catalyst combined with an Au light absorber accelerated hydrogen sulfide-to-hydrogen reactions. The process is an alternative to the conventional Claus process that operates at .
A Fe catalyst combined with a Cu light absorber can produce hydrogen from ammonia () at ambient temperature using visible light. Conventional Cu-Ru production operates at .
