Energy‐Saving Dehydration of Primary Alcohol Under the Formation of Alkenes via a Bifunctional Clay Catalyst

open access: yesChemCatChem, EarlyView.
A commercial acid‐leached bentonite is used in the dehydration reaction of alcohols. A yield of 52% in the alkene formation was observed with FULCAT®‐22 F. IR spectroscopy revealed changes in Brønsted and Lewis acid sites with temperature, driving the reaction to different yields.

In Situ Elucidation of Reaction Mechanisms in Electrocatalysis Using Scanning Electrochemical Microscopy

open access: yesChemCatChem, EarlyView.
This review highlights the principles, recent advances, and emerging applications of Scanning Electrochemical Microscopy (SECM) in electrocatalysis. We discuss its use in carbon dioxide and oxygen electrocatalysis, the detection of short‐lived intermediates, and provide a framework for its implementation in investigations of electrocatalytic interfaces.

Development of a Highly Active Catalyst System with Tuneable Selectivity for the Hydroformylation of the Renewable 1,3‐Diene β‐Myrcene

open access: yesChemCatChem, EarlyView.
Hydroformylation of 1,3‐dienes is widely perceived as inherently slow. In this study, a highly active catalyst system is presented that significantly accelerates the hydroformylation of β‐myrcene and challenges conventional assumptions about diene reactivity. Abstract This study presents an optimized method for the hydroformylation of β‐myrcene using a

Tunable H2/Syngas Production by Chemical Looping Reforming of Methane over La0.6Sr0.4MxM’1‐x(M,M’ = Fe, Mn, Co)O3 Perovskites

open access: yesChemCatChem, 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 ...
