Diplatinum(II)-coordinated polyoxotungstate: synthesis, molecular structure, and photocatalytic performance for hydrogen evolution from water under visible-light irradiation.
The synthesis and molecular structure of a monomeric diplatinum(II) complex composed of mono-lacunary α-Keggin polyoxometalate is described. The polyoxometalate, Cs(3)[α-PW(11)O(39){cis-Pt(NH(3))(2)}(2)]·8H(2)O (Cs-1), afforded by a stoichiometric reaction of mono-lacunary Keggin polyoxotungstate with cis-diamminedichloroplatinum(ii) in water, followed by crystallization from water, was obtaine...
متن کاملPhotodegradation process for the removal of acid orange 10 using titanium dioxide and bismuth vanadate from aqueous solution
In this study, the photocatalytic degradation of azo-dye acid orange 10 was investigated using titanium dioxide catalyst suspension, irradiation with ultraviolet-C lamp and bismuth vanadate under visible light of light-emitting diode lamp. Response surface methodology was successfully employed to optimize the treatment of acid orange 10 dye and assess the interactive terms of four factors. The ...

متن کاملPhotocatalytic hydrogen production from water under visible light irradiation using a dye-sensitized attapulgite nanocrystal photocatalyst.
Attapulgite (ATP), not only as a type of natural and low cost silicate clay mineral but also as a high quality nanosized material with large surface area, layered and lath-like structure, has been found to have a wide variety of industrial applications. The ideal composition of ATP is Mg5Si8O20(OH)2(OH2)4. However, according to previous reports from different countries in the world, it is very ...
متن کاملDevelopment of a Ru complex-incorporated MOF photocatalyst for hydrogen production under visible-light irradiation.
A Ru complex-incorporated Ti-based MOF (Ti-MOF-Ru(tpy)2) has been synthesised by using a bis(4'-(4-carboxyphenyl)-terpyridine)Ru(ii) complex (Ru(tpy)2) as an organic linker. Ti-MOF-Ru(tpy)2 promotes photocatalytic hydrogen production from water containing a sacrificial electron donor under visible-light irradiation up to 620 nm.
