Three Ni-based natural gas steam reforming catalysts, ie, commercial JM25-4Q and JM57-
4Q, and a laboratory-made catalyst (26% Ni on a 5% SiO2–95% Al2O3), are tested in a …

Ethanol dehydration was investigated over commercial H-FER, H-MFI, H-MOR, H-BEA, HY
and H-USY zeolite samples, and alumina and silica alumina for comparison. The catalysts …

Ethylene oxidation by Ag catalysts has been extensively investigated over the past few
decades, but many key fundamental issues about this important catalytic system are still …

Waste lipids, which are generated in enormous quantities worldwide each year (over 10
million tons), are a type of green and sustainable energy source. The production of …

The effectiveness of a recycling approach of the printed circuit board (PCBs), and, thus, the
quality of polymeric constituents, primarily rests on the capacity to eliminate the bromine …

The oxygen species on Ag catalysts and reaction mechanisms for ethylene epoxidation and
ethylene combustion continue to be debated in the literature despite decades of …

In single-site olefin polymerization catalysis, a large excess of cocatalyst is often required for
the generation of highly active catalysts, but the reason for this is unclear. In this work …

Alcohol dehydration is of prominent relevance in the context of biomass conversion. This
reaction can be efficiently catalyzed by alumina surfaces, but the nature of active sites, the …

This study involved the preparation of Al 2 O 3 support and Ni/Al 2 O 3 catalysts through
different methods such as mechanochemical, impregnation, and co-precipitation. These …

Reversible structural transformation between atomic Ag (I) and large Ag metal nanoparticles
(NPs) on γ-Al2O3-supported Ag (Ag/Al2O3) catalysts for H2-assisted NO x selective catalytic …
