The effect of synthesis parameters on ordered mesoporous nickel alumina catalyst for CO2 methanation

[Display omitted] •Compared to hydrochloric and citric acid, using nitric acid during the synthesis led to ordered mesoporous catalysts with higher surface area and superior catalytic activity.•Evaporation induced self-assembly (also known as “one pot”) synthesis technique produced catalysts with hi...

Zusammenfassung:	[Display omitted] •Compared to hydrochloric and citric acid, using nitric acid during the synthesis led to ordered mesoporous catalysts with higher surface area and superior catalytic activity.•Evaporation induced self-assembly (also known as “one pot”) synthesis technique produced catalysts with highly dispersed nickel clusters with very small diameter of around 2.8nm.•Ordered mesoporous nickel alumina catalyst calcined at 700°C exhibited the best results towards CO2 methanation.•At lower reaction temperatures (
