Development of Copper Catalysts Supported on Graphite to Produce Butenes by Acetylene Dimerization
ChemCatChem, EarlyView.The incorporation of copper nanoparticles on the graphite surface leads to the development of catalytic materials capable of selectively hydrogenating acetylene into ethylene and promoting the dimerization reaction to produce butenes. The catalytic properties can be modulated depending on the metal precursor employed. Based on our experimental data, it

ChemCatChem, EarlyView.B substitution in La0,6Sr0,4BxB'1‐xO3 perovskite materials for chemical looping reforming of methane is systematically studied by TPR/TPO experiments. Results suggest a positive effect of Mn on Fe‐based perovskites. Moreover, a novel 3‐step cycle leading to two syngas streams and one pure hydrogen stream is proposed and experimentally verified ...

CO2 Methanation Of Co/CeO2 Prepared by Wetness Impregnation of Co on Flame‐Synthesized CeO2
ChemCatChem, EarlyView.Tailoring the interaction between cobalt (Co) species and flame‐synthesized cerium oxide (CeO2) influences selectivity in CO and CO2 hydrogenation. The chemical state of Co in catalysts with varying loadings was analyzed. Correlations between chemical state, particle size, and catalytic performance offer insights for designing more selective and stable

The Real Thing: Nominal Price Rigidity of the Nickel Coke, 1886–1959 [PDF]
We report that the price of a 6.5oz Coke was 5¢ from 1886 until 1959. Thus, we are documenting a nominal price rigidity that lasted more than 70 years!
