Special Issue Information

Dear Colleagues,

With the rapid growth of modern industrialization and technical development, two critical problems of environmental pollution and energy source shortage are emerging. Utilizing clean energy as a driving force, photocatalysis can convert low-density and unstable solar energy into high-density and steady chemical energy.

Owing to its intrinsic merits of facility, easy control, high efficiency, and ecological safety, photocatalysis is universally considered to be one of the most promising, environmentally friendly, and considerably effective strategies to tackle the aforementioned issues. Undoubtedly, the critical factor influencing photocatalytic efficiency is the photocatalyst itself. Thus, great efforts are urgently required to be devoted to pursuing novel visible-light-responsive photocatalysts with exceptional light absorption ability, favorable carrier transfer ability, and low recombination rate.

Based on above, the Special Issue “Synthesis, Characterization and Application of Photocatalytic Materials” aims to develop novel approaches for the synthesis of novel nanomaterials or nanocomposites with multi-functional photocatalytic activity (including photocatalytic degradation, photocatalytic splitting water, photocatalytic reduction, and so on).

Simultaneously, research concentrating on the development of novel characterization approaches for exploring the interfacial charge dynamics of composite photocatalysts will also be considered for publication in this Special Issue. Within this research topic, original research papers, reviews, and short communications are welcomed.

[Sn(H2PO4)2(TPyHP)](H2PO4)4∙6H2O (2), an ionic tin porphyrin complex, was synthesized from the reaction of [Sn(OH)2TPyP] (1) with a dilute aqueous solution of a polyprotic acid (H3PO4). Complex 2 was fully characterized using various spectroscopic methods, such as X-ray single-crystal crystallography, 1H NMR spectroscopy, elemental analysis, FTIR spectroscopy, UV–vis spectroscopy, emission spectroscopy, EIS mass spectrometry, PXRD, and TGA analysis. The crystal structure of 2 reveals that the intermolecular hydrogen bonds between the peripheral pyridinium groups and the axially coordinated dihydrogen phosphate ligands are the main driving force for the supramolecular assembly. Simultaneously, the overall association of these chains in 2 leads to an open framework with porous channels. The photocatalytic degradation efficiency of methyl orange dye and tetracycline antibiotic by 2 was 83% within 75 min (rate constant = 0.023 min−1) and 75% within 60 min (rate constant = 0.018 min−1), respectively. The self-assembly of 2 resulted in a nanostructure with a huge surface area, elevated thermodynamic stability, interesting surface morphology, and excellent catalytic photodegradation performance for water pollutants, making these porphyrin-based photocatalytic systems promising for wastewater treatment.
