Abstract: A catalyst for methane synthesis is made up from layered double hydroxides represented by the following general formula (1).


[M2+1-xM3+x(OH)2]x+[An−x/n·yH2O]  (1)

In formula (1), M2+ is Ni2+ and M3+ is Al3+ or Cr3+. Further, An− is CO32−. Furthermore, the term x lies within a range of 0.19 to 0.34 (0.19≤x≤0.34), and y is 0 or a positive integer.

Abstract: A carbon dioxide reduction catalyst for hydrogenating carbon dioxide to reduce carbon dioxide to produce a hydrocarbon, containing Fe and Zr as catalytic metals. It is preferable that Ga and Na are further contained as the catalytic metals, and the content of Zr in the catalytic metals is more than 0% by mass and 15% by mass or less.
