Abstract Perovskite‐type oxides have shown the ability to reversibly segregate precious metals from their structure. This reversible segregation behavior was explored for a commonly used catalyst metal, Ni, prevent Ni sintering, which is observed on most support materials. Temperature‐programmed reduction, X‐ray diffraction, absorption spectroscopy, electron microscopy, and catalytic activity tests were follow extent of segregation. LaFe 1− x O 3± δ (0≤ ≤0.2) synthesized using citrate‐based...

The Swiss government has signed the Paris Climate Agreement and various measures need to be implemented in order reach target of a 50 % reduction CO2 emissions Switzerland by 2030 compared with value for 1990. Considering fact that production cement accounts around 2.5 million tonnes which corresponds roughly 7 country's total emissions, following article examines how this amount could put meaningful use create new value-added chain through methanation, thus reduce consumption import fossil...

The raise of regenerative but unsteadily produced energy demands a highly flexible way to store the for time periods when less is than consumed. In current study, it investigated if catalysts based on environmentally more attractive and hazardous health Fe might be able considered as an alternative Ni in CO2 methanation at elevated pressure. For this set with 1–10 wt % supported zeolite 13X analysed 1–15 bar. trends activity well selectivity varying loading pressure are presented....

The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3−δ (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from host perovskite lattice resulting in a regenerable catalyst for solid fuel cell anode applications. Results catalytic tests water gas shift reaction and electrochemical investigations on button-sized demonstrate redox stability LSTN, its potential application cells, ability recover activity completely after...

A small heat of reaction limits the efficiency catalytic hydrogenation CO 2 to form methanol; an improved can be achieved by shifting thermodynamic equilibrium toward formation methanol. The exothermic adsorption products in sorption catalysts is shown increase yield. consist catalytically active Cu particles incorporated into a zeolite, which known strongly absorb water. In addition high yield methanol, catalyst reduces and dimethyl ether. An enhancement factor up 400% for 130% methanol...
