Ni-Based Catalysts for CO Methanation: Exploring the Support Role in Structure-Activity Relationships.

The catalytic hydrogenation of CO to methane is one of the highly researched areas for the production of chemical fuels. The activity of catalyst is largely affected by support type and metal-support interaction deriving from the special method during catalyst preparation. Hence, we employed a simple solvothermal technique to synthesize Ni-based catalysts with different supports and studied the support role (CeO, AlO, ZrO, and LaO) on structure-activity relationships in CO methanation.

Development and Characterization of Natural Chromite Coating on Metal Substrate Using the Plasma Spray Process.

Natural materials are gaining interest as coating feedstock because their "quality to cost" ratio is better and they are more environmentally friendly than most of the synthetic ceramics. They give sufficient protection to metal surfaces against harsh conditions such as corrosion, wear, and high temperature. In the current study, chromite mineral was beneficiated and reduced to two different sizes to be used as feedstock material for thermal spray coating.
