m-BiVO 4 hollow spheres coated on carbon fiber with superior reusability as photocatalyst

Z-scheme 2D-m-BiVO4 networks decorated by a g-CN nanosheet heterostructured photocatalyst with an excellent response to visible light

“…Terephthalic acid reacts with hydroxyl radicals to form hydroxylterephthalic acid, which is highly uorescent. 26,27 The method depends on the PL signals at around 425 nm arising from the hydroxylation of terephthalic acid with hydroxyl radicals generated at the watercatalyst interface. The uorescence intensity of 2-hydroxyterephthalic acid is proportional to the number of hydroxyl radicals produced in water.…”

The highly stable construction of Pt/FeVO4 heterostructure with improving photocatalytic performance and growth mechanism for •O2 and •OH production based on Electron Spin Resonance study

“…Organic pollutant photocatalytic degradation is mainly caused by reactivity with reactive species such as h + , • OH, and • O 2 , which are formed on the surface of photocatalysts when they are irradiated [51,52]. The in uence of various reactive species on photocatalytic degradations reaction was explored on photodegradation of MB to furthermore understand the impact of diverse reactive species on photocatalytic degradations reaction.…”

Supercapacitors for storing energy from coffee bean waste

“…El material del electrodo es uno de los principales factores para determinar el rendimiento de los supercapacitores (Qi et al, 2017). La combinación de los materiales a base de carbono (Aldama, 2015), (carbón negro (Huang et al, 2017), grafeno (Han et al, 2017), nanotubos de carbono (Dai et al, 2017), aerogel de carbón (Yang et al, 2017), carbón vidrioso (Ahmed et al, 2017), carbón activado (Hall et al, 2015), y los materiales de pseudocapacidad (óxidos metálicos) como el óxido de rutenio (RuO2), óxido de níquel (NiO), óxido de manganeso (MnO2), entre otros (Jayakumar et al, 2018), (Marcinauskas et al, 2012), (Ho et al, 2014), son los más utilizados y son combinados para elaborar electrodos compuestos. Actualmente se ha prestado mucha atención a los óxidos metálicos de bajo costo, especialmente al óxido de níquel (NiO).…”
