The relationship of the hydrogen-evolution activity with the optical/electronic characteristics of the polymers is insignificant, suggesting that it might not be the most crucial factor in distinguishing the efficiency. Polymers with shorter bromoalkyl chains exhibit greater hydrogen evolution rates (HERs) than their analogues with longer chains, highlighting the significance of chain length in the reaction. The role of residual Pd as a co-catalyst is investigated. The HER is improved substantially by the presence of Pd. A high HER of 42 mmol g−1 h−1, which is among the highest reported to date, has been achieved. Overall, this work demonstrates that side-chain truncation and modification serve as a straightforward approach to improving the hydrogen-evolution activity. |
