19 Οκτ 2021 · Here we demonstrate catalytic photoreduction of CO 2 to CO in pure water at pH 6–7 with an unprecedented combination of performance parameters: turnover number (TON(CO)) = 72,484–84,101, quantum yield (QY) = 0.96–3.39%, and selectivity (S CO) > 99%, using CuInS 2 colloidal quantum dots (QDs) as photosensitizers and a Co-porphyrin catalyst ...
17 Ιουν 2024 · Values of the total nuclear kinetic energy of hydrogen and oxygen in H 2 O and deuterium and oxygen in D 2 O for liquid water and ice at temperatures near the melting point. The value of the total kinetic energy per molecule, K , is also reported.
22 Νοε 2019 · In this paper we discuss the usage of carbon quantum dots as a potential water disinfection agent especially for photocatalytic degradation of organic molecules and antibacterial water disinfection. Photocatalysis is a process which can be described by the following way: absorbed light generates electron-hole pairs which are followed by ...
1 Μαΐ 2019 · Pristine CQDs synthesized from dopamine as a carbon precursor have been reported for label free sensing of Fe (III) in water with a detection limit of 0.32 μM.The dopamine derived carbon dots exhibited characteristic catechol groups on their surface to selectively bind Fe (III) ions for real water samples.
2 Φεβ 2022 · Water and carbon make a quantum couple. The ultralow friction of water on extremely smooth carbon surfaces has been puzzling researchers for more than a decade. A new theory of the...
27 Μαΐ 2020 · Abstract. Overall water splitting, evolving hydrogen and oxygen in a 2:1 stoichiometric ratio, using particulate photocatalysts is a potential means of achieving scalable and economically...
29 Οκτ 2021 · In this study, the authors used a TiO 2 rutile material for water oxidation and found that the reaction is favoured by superior adsorption of Fe 3+ ions on TiO 2 over the Fe 2+ ions.
