Enhanced Fenton-like catalytic activity and stability of g-C3N4 nanosheet-wrapped copper phosphide with strong anti-interference ability: Kinetics and mechanistic study

Influence of Trace Elements on Neurodegenerative Diseases of The Eye—The Glaucoma Model

“…Copper takes part in Fenton’s reaction, which forms the highly reactive hydroxyl radical. This reaction is well known for involving reduced iron as the major element that catalyzes the break-down of hydrogen peroxide resulting in the active production of free radicals [ 78 ]. Proteins that are involved in cellular copper metabolism include, among others, membrane transporters CTR1 and CTR2, metallo-chaperons, and metallothionein.…”

Generation of singlet oxygen over CeO2/K,Na-codoped g-C3N4 for tetracycline hydrochloride degradation over a wide pH range

“…In addition, most heterogeneous Fenton-like catalysts exhibit good oxidation performance generally under acid conditions/or with the help of light irradiation/electrical field, which restricts their applications. 8–10,12–15,25–28 To overcome these shortages, one of the strategies is to develop novel highly-effective Fenton-like catalysts to activate H 2 O 2 to generate long-life-time ROS (such as 1 O 2 ).…”

“…[7][8][9][10] Recently, heterogeneous Fenton-like reactions have generated fast increasing interest for the catalytic degradation of organic pollutants in wastewater because they can overcome the shortage of traditional Fe ion-based homogeneous Fenton catalytic reactions, such as able to work under acidic media ( pH = 3-5), the formation of iron-containing sludge and poor recyclability. [7][8][9][10][11][12][13][14][15][16][17][18] In the traditional Fenton reaction, the hydroxyl radical ( • OH) is generally regarded as the main reactive oxygen species (ROS) owing to its high oxidizing capacity (Φ: 2.8 V). However, other ROS (such as • O 2 − , 1 O 2 , etc.)…”

“…19 Up to now, there are still a few reports on the generation of 1 O 2 by the activation of H 2 O 2 over heterogeneous Fenton-like catalysts. 12,16,[19][20][21][22][23] Thus, it is still a challenge to realize the conversion of • O 2 − into 1 O 2 over a heterogeneous Fenton-like catalyst by activating H 2 O 2 in the dark. In addition, most heterogeneous Fenton-like catalysts exhibit good oxidation performance generally under acid conditions/or with the help of light irradiation/electrical field, which restricts their applications.…”

“…In addition, most heterogeneous Fenton-like catalysts exhibit good oxidation performance generally under acid conditions/or with the help of light irradiation/electrical field, which restricts their applications. [8][9][10][12][13][14][15][25][26][27][28] To overcome these shortages, one of the strategies is to develop novel highly-effective Fenton-like catalysts to activate H 2 O 2 to generate long-life-time ROS (such as 1 O 2 ). Cerium oxide (CeO 2 ) possesses many unique properties, such as abundant oxygen vacancies, unique electronic structure (4f 15 d 1 orbital), high oxygen storage capacities, adequately positive valence band, and unique Ce 4+ /Ce 3+ redox properties, which enable it to have promising applications in the fields of photocatalytic H 2 evolution, organic pollutant degradation and CO 2 reduction, CO oxidation, the steam reforming reaction, etc.…”
