The supported copper based catalysts could be potential candidate for the selective catalytic hydrogenation of acetic acid to produce ethanol instead of noble metals. In this work, a series of highly efficient bimetallic Cu-In/SBA-15 catalysts were d

Hybrid catalysts for the selective catalytic reduction of NO by NH3, which have been introduced as physical mixtures between an oxidation catalyst and an SCR catalyst, have been prepared by precipitation of the former onto the latter. Mn oxide, CeO2,

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
