By carefully adjusting those properties, the best material, CTF-02-Bpy 0.66 , reaches the highest hydrogen evolution rate, achieving 7.24 mmol h -1 g -1 under visible light irradiation in the presence of a sacrificial compound. Importantly, these investigations show that the balance between all properties that might affect (photo)catalytic activity is crucial to accurately describe the materials performance and to understand the parameter that affects most its performance.
