Formation of K–Cr Titanates from Reactions of Chromite and

Other titanates are absent in the runs with rutile at any chromite/rutile ratios. The possible reason is an insufficient amount of Fe, first of all, Fe 3+. This suggestion is supported by the experiments in the chromite-ilmenite-K 2 CO 3 –H 2 O–CO 2 system (runs B1, B1-1, B1-2, B1-3, B1-4, B2; Table 2). Products of these experiments contain ...

Sequential Photo-oxidation of Methanol to Methyl Formate on …

Methyl formate is produced from the photo-oxidation of methanol on preoxidized TiO2(110). We demonstrate that two consecutive photo-oxidation steps lead to methyl formate using mass spectrometry and scanning tunneling microscopy. The first step in methanol oxidation is formation of methoxy by the thermal dissociation of the O–H bond to yield adsorbed …

How To Use Rutile In Your Pottery – MommyLikeWhoa

Rutile is a mineral that is used as a glaze in pottery. It is a source of titanium dioxide, which is a white pigment that is used to produce a wide range of colors in glazes. Rutile is also used as a flux, which helps to lower the melting point of the glaze and improve its flow. The rutile used to make potassium titanate is a feedstock in ...

Amorphous TiO2 as a Photocatalyst for Hydrogen

Band gap characteristics of amorphous TiO2 are compared with experimental data for amorphous as well as crystalline (rutile and anatase) TiO2 phases. Analysis of electronic properties suggests that amorphous TiO2 may prove as a cheaper, more abundant, but somewhat less efficient photocatalyst as compared to crystalline TiO2.
