The reaction rate laws derived from the elementary reaction
steps in Scheme 1 a and b, respectively, are shown as follows (14):
The second major reason is that solid state reaction is generally not an elementary reaction
, in which the reaction model varies with temperature, and the reaction might involve several steps with different activation energies.
The main objectives of the project are (i) to understand by a catalysis by design approach the requirements for inorganic catalyst systems to speed up elementary reaction
steps and valorise biomass with a focus on conversion of cellulose into fuels and chemicals; (ii) using these nanoscale insights to develop novel catalysts based on abundant elements for the conversion of biomass and (iii) to develop three proof of concept studies at laboratory scale to convert cellulose/sugar feedstocks into fuels and chemicals - specific attention will be paid to catalyst robustness.
In particular, the Arrhenius pre-expo-nential for this elementary reaction
differs slightly from that published in an our previous work  due to the modification introduced in its evaluation, as illustrated in the Computational Details section.
The collision of molecules causes chemical reactions, which comprise an elementary reaction
for specified reactant and product molecules, they say, and a balanced stoichiometric reaction for an elementary reaction
yields the number of each type of molecule according to the conservation of atoms, mass, and charge.
The kinetic equations of each elementary reaction
can be written as:
t] are activation energies of elementary reaction
of initiation, propagation, and termination, consequently.
The extraordinary structural diversity of transition metals, along with the rich variety of elementary reactions
that take place over those centres, are attributes that will extend the usefulness of FLPs far beyond the present (mainly) hydrogenation reactions and should allow developing new catalytic processes unreachable for current homogeneous catalysts.
A rare irreversible consecutive reaction network had previously been proposed, to describe the observed kinetics of such a complex oxidation system, involving hundreds of elementary reactions
, consisting of the following two simple steps [17, 19]:
The twenty-one contributions that make up the main body of the text are devoted to rate constants and their temperature-dependence in elementary reactions
, rate constant calculation of benzylperoxy radical isomerization, statisticodynamical and multiscale modeling of cluster dissociation, and a wide variety of other related subjects.
The process is composed of several elementary reactions
, such as protonation, deprotonation, and dehydration.
