Identifying active sites and designing rationally heterogeneous catalysts are not inherently straightforward due to their complexity. Here, the authors reveal the nature of active sites for efficient C–H bond activation in C1-C4 alkanes over bare Z

The reaction mechanism of the direct conversion of ethylene to propene over Ni-containing catalysts is assumed in literature to comprise (i) ethylene dimerization to 1-butene, (ii) butene isomerization and (iii) metathesis of 2-butene with ethylene t

Bulk CrZrOx, supported CrOx/LaZrOx, and CrOx/Al2O3 catalysts were prepared with Cr surface site density varying between 0.04 and 2.3 nm−2. They were characterized by BET, XRD, temperature-programmed reduction with H2, and NH3 temperature-programmed

Since CO 2 hydrogenation into higher hydrocarbons is an attractive approach to mitigate greenhouse effect and to reduce reliance on fossil feedstock, this reaction has been intensively studied over Fe-based catalysts. They had, however, to be promote

Ni catalysts supported on mixed ZnO Al2O3 and on pure ZnO and Al2O3 were prepared, characterized by XRD, TPR, and XPS, and tested in long-term methane dry reforming at low temperature (400 °C). Depending on Zn/Al ratio in the supports, the catalysts

Non-oxidative propane dehydrogenation (PDH) was investigated over unconventional catalysts, i.e. binary La2O3-ZrO2 and Y2O3-ZrO2 materials with or without tiny amounts (0.005 or 0.05 wt.%) of Ru in form of nanoparticles with the size of about 1.1 nm.
