Enrolling reactive oxygen species in photon-to-chemical energy conversion: fundamentals, technological advances, and applications

Supramolecular luminescent Pt(ii) tweezers: aggregation studies and 1O2 production

“…In this way, platinum compounds have been observed to act as photosensitizers to produce singlet oxygen, 1 O 2 , being suitable candidates to be carefully analyzed in this field or in other applications such as photocatalysis, or even degradation of contaminants. 50,51…”

Optimization Method Based on Simplex for Surface Area Improved Photocatalytic Performance of g-C3N4

“…The production of 1 O 2 is also in agreement with the results of the reusability and TGA experiments, as it is typical that materials capable of producing 1 O 2 show high stability. 75 We additionally performed BPA degradation experiments by purging the reaction suspension with N 2 (end O 2 concentration 0.56−0.65 mg/L), which resulted in a similar BPA degradation rate as during the experiments where NaN 3 and HCOOH were employed. We assume that some surfaceadsorbed oxygen was left that could participate in the generation of ROS.…”

“…72,84 Furthermore, due to the generation of 1 O 2 , the application possibilities of the MR12 photocatalyst increased to water remediation using solar irradiation (Figure S13c), organic synthesis, 82,85 detoxification, and decontamination processes. 75 For further information, refer to the Supporting Information.…”

“…2,71,76,79,80 As the quenching with NaN 3 or HCOOH did not completely stop the photooxidation, this probably means that not all O 2 −• is converted to 1 O 2 and both O 2 −• and 1 O 2 are the responsible active ROS for the degradation of BPA. Because the MR12 photocatalyst produces O 2 −• and 1 O 2 , it acts simultaneously as a Type I and Type II ROS photosensitizer, 81,82 which usually requires organometallic complexes, usage of plasmonic metals on different supports, 75 or large organic macromolecules. 76 Moreover, the generation of singlet oxygen is generated probably with the dismutation reaction, hole oxidation, and energy transfer as observed in ref 70 and our experiments.…”

Fullerene C70as Photoredox Catalyst for the Synthesis of Pyrrolo[2,1‐a]isoquinolines by 1,3‐Dipolar Cycloaddition‐Aromatization Sequence

“…In addition to that, the singlet oxygen generation ability of the catalyst plays a pivotal role in photocatalysis. Interestingly, the singlet oxygen generation ability of fullerene C 70 is significantly higher than the existing commercial photoredox catalysts such as eosin Y, rose bengal, methylene blue, and [Ru(bpy) 3 ]Cl 2 providing another perspective towards its application as a potential photoredox catalyst [28–30] …”
