Physicochemical characteristic of neodymium oxide-based catalyst for in-situ CO2/H2 methanation reaction

Carbon dioxide emission to the atmosphere is worsened as all the industries emit greenhouse gases (GHGs) to the atmosphere, particularly from refinery industries. The catalytic chemical conversion through methanation reaction is the most promising technology to convert this harmful CO2 gas to wealth...
