Abstract
Linear poly(p‐phenylene)s are modestly active UV photocatalysts for hydrogen production in the presence of a sacrificial electron donor. Introduction of planarized fluorene, carbazole, dibenzo[b,d]thiophene or dibenzo[b,d]thiophene sulfone units greatly enhances the H2 evolution rate. The most active dibenzo[b,d]thiophene sulfone co‐polymer has a UV photocatalytic activity that rivals TiO2, but is much more active under visible light. The dibenzo[b,d]thiophene sulfone co‐polymer has an apparent quantum yield of 2.3 % at 420 nm, as compared to 0.1 % for platinized commercial pristine carbon nitride.
Highlights
The hydrogen evolution rates were incorrectly calculated, but by a common scaling factor
The trends observed between materials and the overall conclusions made in the Communication remain valid
The apparent quantum yields at 420 nm for P1K, P6, and P7 should be corrected to 0.4% (±0.1%), 2.2% (±0.2%), and 7.2% (±0.3%), respectively
Summary
The hydrogen evolution rates were incorrectly calculated, but by a common scaling factor.
