Additionally, we explored a meta-stable state photoacid with a longer excited state half-life, with observed stable CO2 release upon irradiation, while the CO2 release capacity is still limited. Future studies should consider the quantum yield of the photoacid and aim to design photoacid systems with high pKa values in the ground state. This approach will not only enhance the effective capacity of the photoacid system for carbon capture but also simplify the system by relying solely on the bicarbonate buffer, enabling better system control. Our research opens up new avenues for the development of novel photochemical carbon capture strategies. Looking ahead, future developments will aim to create photochemical systems that harness sunlight, thereby enabling energy-efficient carbon capture without the need for external energy inputs. This advancement has the potential to revolutionize the field of photo-swing carbon capture, allowing for efficient and controlled capture and release of CO2, facilitating its further utilization or storage.
