It examines the developments in this field that have been facilitated by artificial intelligence tools, especially machine learning algorithms. The photocatalytic generation of hydrogen has been the subject of extensive study in recent years, as the necessity for higher efficiency and hydrogen production rates represents a crucial step in the development of this technology for its mass deployment. The known difficulties of these systems pertain to the complexities associated with the photocatalysts, including the effect of reactants, the synthesis process, and their efficiency, particularly in harvesting sunlight. Moreover, the design of the reactor is a challenging undertaking, particularly in light of the dynamic behavior and the interaction between photons, solutions, photocatalysts, and co-catalysts that must be considered in the photocatalytic production of hydrogen. Research on this subject must consider the use of green materials and processes for synthesis, avoid extensive experimentation to reduce the carbon footprint, and seek efficient and less resource-intensive computational resources. To surmount the challenges inherent to the synthesis and development process, while simultaneously enabling the establishment of structure–performance relationships for knowledge acquisition, high-performing computational methods are key.

However, managing radioactive waste, particularly iodine, remains a critical challenge for its long-term viability. Recent studies indicate that nitrogen-rich adsorbents exhibit a strong affinity for iodine due to forming charge-transfer complexes with I<small>₂</small>, enhancing interaction forces. In this context, an N-heteroatom engineering strategy was employed to synthesize a hybrid zirconium triethylenetetramine (ZrT) exchanger of the class of tetravalent metal acid (TMA) salts. To further improve its potential for large-scale industrial applications, ZrT was subsequently fabricated into a spherical ZrT@PVDF composite granule for iodine adsorption. Adsorption experiments revealed that ZrT and ZrT@PVDF exhibit outstanding iodine capture performance in vapor (1262.5 and 945.2 mg g<small>⁻¹</small>), including saturated I<small>₂</small> (886 and 706 mg g<small>⁻¹</small>) and I<small>₃</small><small>⁻</small> (NaI/I<small>₂</small>) (920 and 746 mg g<small>⁻¹</small>) aqueous solution and organic phase (772 and 598 mg g<small>⁻¹</small>). However, the presence of single, double, and triple interfering ions had only a marginal impact on the iodine removal efficiency of both adsorbents. Spectroscopic, kinetic, and several isothermal studies demonstrate that iodine adsorption occurs through both physisorption and chemisorption mechanisms. The interaction between iodine and the nitrogen atoms of ZrT, leading to the formation of a stable charge-transfer complex, contributes to the high performance of the material in adsorption applications. Notably, ZrT@PVDF exhibited outstanding regeneration and reusability, retaining 87% of its initial adsorption capacity over five adsorption–desorption cycles, highlighting its potential for practical applications.
