Abstract

CO2 Methanation In their Research Article on page 14434, J. Bao, J. Zeng et al. report PdFe intermetallic nanocrystals with high activity and stability in CO2 methanation.

Microenvironment Engineering of Single/Dual‐Atom Catalysts for Electrocatalytic Application

“…[ 223,227 ] For example, some noble‐metal (e.g., Ag, Au, Pd) based SACs have been considered as the active materials for catalyzing the CO 2 to CO for their excellent intrinsic selectivity for CO evolution. [ 228–230 ] In addition, non‐precious metals such as Ni, Fe, and Cu‐based catalysts are also explored for electrocatalytic CO 2 RR. [ 231,232 ] Among them, Cu SACs as a unique catalyst has been known to reduce CO 2 to hydrocarbons, including methane, ethylene, acetate, and ethanol.…”

Engineering heterogenous catalysts for chemical CO2 utilization: Lessons from thermal catalysis and advantages of yolk@shell structured nanoreactors

“…95%) with almost total methane selectivity, owed to the presence of Fe within the active phase. A similar Pd-Fe bimetallic system was investigated by Luo et al [205], which purported the intermetallic bonding, between the two metals to be a key factor in its performance through the maintenance of surface Fe crystallites. This formulation was so effective, there was essentially no activity loss after 60 hours of continuous operation.…”
