Abstract

Compositional studies of electrode films based on RuO2-TiO2 mixts., prepd. by pyrolytic oxidn. of RuCl3.3H2O-diisopropoxybis(2,4-pentanedionato)titanium deposits show that these materials contain large amts. of carbon and hydrogen impurities. This evidence supports the idea that crystallites of the RuO2-TiO2 solid soln. are sepd. by large amorphous areas where chem. impurities are accumulated. The porosity of these areas is responsible for the relatively high charge-storage capacity of the mixed-oxide electrodes found by voltammetry. [on SciFinder (R)]

Titanium dioxide

Titanium dioxide, also known as titanium(IV) oxide or titania taɪˈteɪniə, is the inorganic compound with the chemical formula TiO2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. It is a white solid that is insoluble in water, although mineral forms can appear black. As a pigment, it has a wide range of applications, including paint, sunscreen, and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million tonnes.

Electrocatalyst

An electrocatalyst is a catalyst that participates in electrochemical reactions. Electrocatalysts are a specific form of catalysts that function at electrode surfaces or, most commonly, may be the electrode surface itself. An electrocatalyst can be heterogeneous such as a platinized electrode. Homogeneous electrocatalysts, which are soluble, assist in transferring electrons between the electrode and reactants, and/or facilitate an intermediate chemical transformation described by an overall half reaction.

Hydrogen

Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula . It is colorless, odorless, tasteless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter. Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds.
