DOI: 10.1002/cplu.202500284
Abstract: Catalyst precursors for methanol synthesis prepared by coprecipitation, such as Cu/Zn‐based hydroxycarbonates, are generally formed within two steps. The initial precipitation phase (nucleation) leads to a suspension from which, in a subsequent aging phase, the… read more here.

DOI: 10.1021/acs.iecr.7b03251
Abstract: Industrial and nanometallic catalysts are composed of an active component of metallic nanoparticles tailored by one or more additives and/or other metals, which should be in interaction and highly dispersed on a support. Therefore, it… read more here.

DOI: 10.1039/d0gc00571a
Abstract: Potassium salt prepared AMO-MgxAl-LDH(K) (x = 2–5) have been studied as catalyst precursors for biodiesel synthesis. Calcined potassium salt prepared [AMO-Mg0.75Al0.25(OH)2](CO3)0.17K0.01 {AMO-Mg3Al-LDH(K)} with high surface area (366.1 m2 g−1) and Lewis basicity density (2.87 μmol… read more here.
