The effects of Ni/Fe loading molar ratios, catalytic temperatures, and steam flow rates were explored to optimize catalyst performance and operational parameters for hydrogen (H2) production. Attributed to the formation of a spinel phase, the Ni–Fe1.5/hydrotalcite catalyst demonstrated the highest catalytic activity during the catalytic reforming process, yielding 51.41 mmol/gPP of H2 (where PP denotes polypropylene) without steam and 121.97 mmol/gPP with steam (8 mL/h). Additionally, carbon nanomaterials produced at a catalytic temperature of 800°C showed the highest carbon yield. Furthermore, the catalyst exhibited robust cyclic stability, retaining approximately 90.3% of its initial H2 yield after five consecutive reaction-regeneration cycles, with its mild deactivation primarily driven by bimetallic sintering and amorphous carbon encapsulation. Possible reaction pathway mechanisms of PP and methane (CH4) proposed based on Gaussian simulations demonstrate consistency with the experimental results. Finally, the mechanism of catalytic temperature on the production of carbon nanotubes (CNTs) was proposed.

In this regard, antibacterial photodynamic therapy (aPDT) has gained increasing attention as a non-invasive approach that utilizes light-activated photosensitizers to generate targeted reactive oxygen species (ROS), leading to rapid bacterial inactivation with minimal resistance development. Among various photosensitizers, Zn(II) complexes have shown promising potential due to their favorable biocompatibility, photophysical properties, and tunable coordination chemistry. Unlike heavy-metal photosensitizers, Zn(II) complexes owe their photophysical performance to extended macrocyclic π-systems rather than metal spin-orbit coupling, making them uniquely suited for biocompatible aPDT. This review critically examines recent advances in Zn(II)-based complexes as photosensitizers, including phthalocyanines, porphyrins, chlorins, and curcumin systems, highlighting structure–activity relationships (SARs), ROS generation mechanisms, and antibacterial efficacy against both Gram-positive and Gram-negative pathogens, including multidrug-resistant strains. Key design strategies such as cationic functionalization, polymer conjugation, and hybridization with antimicrobial peptides are discussed.
