Direct Z-scheme Fe2(MoO4)3/MoO3 heterojunction: Photo-Fenton reaction and mechanism comprehension

In Situ Growth of Z-Scheme Co/Al-LDH@Co3O4@Co-F Heterojunctions with Interfacial Enhancement and Synergistic Effects on a Cobalt Foam Surface for Environmental Remediation Studies

“…According to DFT calculations, Co/Al-LDH has a lower Fermi level and smaller work function than Co 3 O 4 . When two photocatalysts are in contact with each other, electrons will flow spontaneously from Co/Al-LDH to Co 3 O 4 until their Fermi levels align . When the equilibrium is achieved, Co/Al-LDH becomes positively charged for the electron loss, whereas Co 3 O 4 becomes negatively charged because of electron accumulation at the interface, and a strong internal electric field is established at the interface of the Co/Al-LDH@Co 3 O 4 heterojunction.…”

Controversial mechanism of simultaneous photocatalysis and Fenton-based processes: additional effect or synergy?

“…It is worth mentioning the different terminologies of synergy that are often met in the literature for heterogeneous systems that are assumed to trigger simultaneously photocatalysis and Fenton-based processes: synergistic catalysts, photochemically versatile materials, photocatalytically-assisted Fenton, and photocatalytic-self-Fenton. [10][11][12][13][14][15] Martin Motola After a 2.5-year postdoctoral fellowship at the Center of Materials and Nanotechnologies, University in Pardubice, Czech republic, Dr. Martin Motola returned to his alma matter where he is currently working as Associate Professor at the Department of Inorganic Chemistry, Faculty of Natural Sciences, Comenius University Bratislava, Slovakia. Dr. Martin Motola conducts scientific research related to environmental remediation and energy including water and air treatments, hydrogen production, batteries, and solid oxide fuel and electrolysis cells.…”

“…5). 10,44 In these above-mentioned examples, a strong issue is again raised since the individual processes have not been investigated, thus Fig. 2 The misconception of synergy between photocatalysis and Fenton-based processes based on degradation extents of organic pollutant removal.…”

N-Doped TiO2 Coupled with Manganese-Substituted Phosphomolybdic Acid Composites As Efficient Photocatalysis-Fenton Catalysts for the Degradation of Rhodamine B

“…1 However, the waste generated by human production and life has gradually caused pollution to the water system, the trend of which is exacerbated with the continuous development of worldwide industry. 2 Improper disposal of wastes from industrial processes, such as pesticides, pharmaceuticals, and organic dyes, has led to an egregious level of water pollution worldwide. 3 Among these, organic dyes are widely used in leather, printing, cosmetics, and textiles.…”
