Despite its fleeting existence, H2CO3 plays an important role in the global carbon cycle and in biological carbonate-containing systems. The short lifetime in water and presumed low concentration under all terrestrial conditions has stifled study of this fundamental species. Here, we have examined ...
Hongwei Ji1,2, Wenjing Song 1,2, Wanhong Ma1,2, Chuncheng Chen 1,2 ✉ and Jincai Zhao 1,2 ✉ Haematite (α-Fe2O3) has been extensively investigated as a photoanode in photoelectrochemical water oxidation, but the prod- uct O2 has a low economic value....
Conclusions We have prepared homogeneous mixtures of [bmim]Fe(III)Cl4–H2O at x(H2O) = 5.88–30% and above 80%, which showed the presence of both Brønsted and Lewis acids at x(H2O) ≤ 30%, and only Lewis acids at x(H2O) ≥ 80% by FT-IR. Raman spectra showed Fe(III)Cl4...
and Figure 2 represents the crystal structure of the novel compound according to the formula [Cu(tda)(9heda)(H2O)]·2H2O in a very asymmetrically elongated octahedral coordination, type 4 + 1 + 1 *, where * denotes the above referred Cu⋯O2(aqua) weak contact (see discussion below). ...

This suggests that the exposure of WO3 to H2 directly results in a hydroxylated surface and the corresponding H2O desorption turns out to be a very efficient mechanism to generate a reduced oxide surface, with important consequences on the electronic structure of this oxide....
