Potential zero free chargeThe hydrogen peroxide reduction reaction (HPRR) on Pt(111) has been studied for the first time in acid to neutral pH values in the absence of anion specific adsorption using the HMRDE configuration. The onset for the reduction is ca. 0.95 V (RHE) for the Pt(...
The potential of hydrogen peroxide to reduce the levels of salivary thiol precursors of oral malodor was investigated in-vitro and in-vivo. In both cases the concentration of thiol groups was determined colorimetrically by quantitative reaction with 4,4'-bis (dimethylamino) diphenyl carbinol. Addition...
Watanabe, H,Yamazaki, H,Wang, X. Y,Uchiyama, S.Oxygen and hydrogen peroxide reduction catalyses in neutral aqueous media using copper ion loaded glassy carbon electrode electrolyzed in ammonium carbamate solution. Electrochimica Acta . 2009
Electro-reduc- tion of hydrogen peroxide starts at 0.75 V (reaction 2) in acidic medium. The inset to Figure 3 shows that hydro- gen peroxide reduction takes place in the potential range where the cathodic peak develops in absence of hydrogen peroxide, akin to that observed by Mocchi et al...
Ions off-elements(III–VI) form peroxide complexes. The peroxo group occupies either one (OOH) or two (OO) coordination sites. U(VI), Np(IV) binds up to 3 peroxo groups. Oxidation or reduction reactions proceed intramolecularly. In the case of Yb2+, Sm2+, U3+, Ce4+(in an acid ...
The electrocatalytic oxygen reduction reaction (ORR) to hydrogen peroxide (H2O2) by a two-electron pathway is regarded as a green and substitute technique to the anthraquinone method. However, an important challenge in H2O2 electrogeneration is to design selective and economic electrocatalysts. Herein...
Oxygen reduction and hydrogen evolution compete in the potential space at low headspace O2 concentrations. e Picture of the 150 mL batch reactor and a fuel cell powered RC car that the headspace hydrogen direct injection successfully driven. f Hydrogen peroxide concentrations tracked for the first...
Electrochemical oxygen reduction has garnered attention as an emerging alternative to the traditional anthraquinone oxidation process to enable the distributed production of hydrogen peroxide. Here, we demonstrate a selective and efficient non-precious electrocatalyst, prepared through an easily scalable mild ...
Hydrogen Peroxide In subject area: Materials Science Bioelectrochemical systems (BECs) are the systems employing the electrochemically active microorganisms to catalyze the production of bioelectricity and also value-added chemicals (such as H2, hydrogen peroxide, and other valuable products) from waste org...
For a long time, hydrogen sulfide (H2S) has been considered a toxic compound, but recent studies have found that H2S is the third gaseous signaling molecule which plays a vital role in physiological and pathological conditions. Currently, a large number
