Cyclohexene was converted to cyclohexane exclusively on acidic erionite activated either by double spillover or thermally, the latter activation being less efficient than the former. It is the first time that hydrogenating sites have been created by spillover on a basic form of zeolite....
The advantage of water is that it is fluid at lower temperatures and also more easily replaceable than most [oxides]. 水的优点是它在较低温度下是流体,并且比大多数[氧化物]更容易替换。 figure 4 Thus H2SO4 and KOH were considered to be acidic and basic hydrates. respectively, and could be ...
BOF slag usually possesses relatively high basicity (ratio of alkaline oxides to acidic oxides) and presents in different mineral phases, including tricalcium silicate (C3S), dicalcium silicate (C2S), dicalcium ferrite (C2F), MgO, CaO and RO phase (CaO, MgO, MnO and FeO solid solution) (Be...
Examples of the coloring agent or the pigment include phthalocyanine-based, indigo-based, quinacridone-based, metallic complex salt-based and other various azo pigments; basic or acidic water-soluble dyes; azo-based, anthraquinone-based, perylene-based and other oil-soluble dyes; titanium oxide, iro...

Acidic conditions: (5.9)O2+2H++2e−=H2O2 (5.10)H2O2+2H++2e−=2H2O The actual ORR process is usually a mixture of four-electron and two-electron reactions. In most cases, the four-electron pathway is preferred because the four-electron process is more efficient, while the hydrogen peroxid...
energies. While OCFGs are simply classified as acidic and basic, the reactivity of OCFGs can counterintuitively change profoundly by the carbon microenvironment because of the electron density delocalization resulting from the neighboring aromatic rings or the various OCFGs. Using probe reactions, we ...
is the Volmer reaction, wherein an electron (e−) transfers to the electrode can react with the H+or H2O in acidic or alkaline solution on a void active site of the catalyst to produce the adsorbed hydrogen atoms (Hads) (Eq. (1) or (2)). Subsequently, the second step is ...
high priority in view of the last five years scientific reports, while not at all ignored the previous history. Apart from the advancements in the field the core science behind electrocatalytic OER in acidic, basic as well as neutral medium, characteristics of an OERelectrocatalyst, expressions ...
As water could be precluded as a reactant from the 2-electron process of LiOOH (that is, in acidic and basic conditions), it may in theory boost the energy density and energy efficiency of water-based Li-O2 cells. A distinct battery chemistry was discovered for water-contaminated Li-O2 ...
