Chlorophyll
The substance that acts as a catalyst during photosynthesis is an enzyme called Rubisco. Rubisco plays a key role in the carbon fixation process, where it catalyzes the reaction that combines carbon dioxide and ribulose-1,5-bisphosphate to form 3-phosphoglycerate in the Calvin cycle.
a catalyst
It speeds up photosynthesis because it acts as a catalyst.
Chlorophyll is NOT really a catalyst. The presence of chlorophyll in the absence of light does not catalyze photosynthesis. Chlorophyll plays a part in photosynthesis, it captures light energy.

The substance is "Road Salt" or coarse sodium chloride.
The catalyst for photosynthesis is sunlight. Sunlight provides the energy needed to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen in the presence of chlorophyll.
