Elemental Analysis of Catalysts in a Fixed‐Bed Reactor by Laser‐Induced Breakdown Spectroscopy
ChemCatChem, EarlyView.The “Elemental Composition” provides information about promoters and poisons found in heterogeneous catalysts. Access to this piece of information under reaction conditions remains yet an unsolved challenge. This work explores the potential and limitations of laser‐induced breakdown spectroscopy (LIBS) as an in situ reactor diagnostic technique ...

Carbon Energy, EarlyView.Herein, a rational photoanode design enhances H2O2 production via H2O oxidation in a PEC system, with Mo‐doped BiVO4 films and planar Co‐py co‐catalysts achieving optimal performance at 8.4 μmol·h−1·cm−2. Mo6+ doping tailors Fermi level alignment while Co‐py stabilizes *OH intermediates and promotes H2O2 desorption, as confirmed by operando analyses ...

A system of nonlinear degenerate parabolic equations
, 1986 Existence, uniqueness, regularity and asymptotic behavior results are proved for the coupled system of degenerate parabolic equations \[ u^ i_ t(t,x)=k_ iu^ i(t,x)K(P(t,x))P_{xx}(t,x), \] \[ P(t,x)=\sum^{N}_{1}u^ i(t,x),\quad u^ i(t,0)=u^ i(t,1)=0,\quad u^ i(0,x)=u^ i_ 0(x) \] with \(i=1,2,...,N\), and (t,x)\(\in [0,T]\times [0,1]\). K is assumed to be

Chemistry – A European Journal, EarlyView.Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
