Coatings based on TiO2 are extensively investigated material for the preparation of surfaces which are referred as self-cleaning. Under solar illumination these coatings catalyze pollutants degradation and enhance their removal from the surface due to photoinduced superhydrophilicity [1]. There are ...

Nickel hydroxide (Ni(OH)2) is a promising pseudocapacitive material owing to its high theoretical capacitance and reversible Ni2+/Ni3+ redox activity. Here we demonstrate that carbonate incorporation during hydrothermal synthesis is the key structural factor limiting its electrochemical performance. ...

Nickel hydroxide (Ni(OH)2) is a layered hydroxide material that possesses a characteristic
two-dimensional layered structure, in which nickel cations are sandwiched between
hydroxide ion sheets. This structural arrangement facilitates ion diffusion and reversible
redox reactions, making Ni (OH)2 ...

Ni hydroxides;XANES;EXAFS;pseudocapacitor;OER;
In situ Ni K-edge XANES and EXAFS analysis is used to elucidate how chemical modification of Ni-hydroxide materials governs the oxidation behavior, redox reversibility, and accessibility of Ni2+ ions across pseudocapacitive and oxygen evolution reaction (OER) regimes. The redox activity of the Ni2+/ ...

Fenton-like advanced oxidation processes (AOPs) for removing organic pollutants from water are among the most industrially applicable methods. Bimetallic Cu-Fe catalysts supported on porous silica with interparticle mesoporosity (KIL) were prepared as heterogeneous photo-Fenton-like catalysts for po ...

pseudocapacitors;layered-double hydroxides;cobalt hydroxide;redox processes;in situ x-ray absorption spectroscopy;
Cobalt hydroxide and other first-row transition metal hydroxides have gained significant attention as pseudocapacitor materials due to their rapid and reversible redox processes. Their layered structures facilitate interactions between electrolyte anions and cobalt cation sites within the bulk of th ...

The Sn-modified TiO2 photocatalysts are prepared by low-temperature sol-gel processing based on organic titanium
and tin precursors with varied Sn concentrations (from 0.1–20 mol .%). The role of Sn dopant as the
promotor of the formation of TiO2 rutile crystalline phase is explained and the optim ...

The objective of this research was to investigate how the photocatalytic activity of pure TiO2 can be improved by
SnO2 modification. Different molar ratios of tin to titanium were prepared. The correlation between tin concentration
and structural properties was investigated to explain the mechanis ...
