The invention discloses a dehydrogenation catalyst for non-precious metal and preparation method thereof. The catalyst of the invention comprises the carrier and the main and auxiliary catalyst. The carrier is Mg-Al-O compound. The auxiliary catalyst selects at least one kind from the scope of tin, indium and gallium; the main catalyst is at least one kind selected from the scope of copper, zinc, chromium, vanadium, molybdenum and gallium. The preparation method is to bake the ingredients in the microwave field to obtain the Mg-Al-O hydrotalcite containing the main and auxiliary catalysts, which is the catalyst provided by the invention. The catalyst of the invention can be applied to the dehydrogenation reaction of both cycloalkane and paraffin with high target selectivity and good reaction stability and regeneration. 本发明公开种非贵金属脱氢催化剂的制备方法和应用。本发明的催化剂包括载体及主、助催化剂，所述载体为Mg-Al-O复合氧化物，所述助催化剂选自锡、铟及镓中的至少种；所述主催化剂为铜、锌、铬、钒、钼及镓中的至少种。其制备方法为在微波场中焙烧制得含有主、助催化剂的Mg-Al-O水滑石，得到本发明的催化剂。本发明的催化剂应用于环烷烃和链烷烃的脱氢反应，具有高的目标产物选择性和较好的反应稳定性和
