Sulfuric acid, hydrogen peroxide, sodium carbonate. Not catalysts but reagents. Most currently come from fossil fuel feedstock but that isn't essential.
Why would any of those compounds come from fossil fuels? Sulfur is mined, hydrogen peroxide is water with some oxygen taken off, and sodium carbonate is made from salt and limestone
