Here, FeAlOx catalytic deconstruction of polyethylene in a domestic microwave oven is reported. With the starting weight ratio of FeAlOx to polyethylene at 1:1, the concentration and yield of H2 reach up to 67.85 vol% and 48.1 mmol g&minus:1plastic, respectively. CNTs@Fe3O4/Fe3C/Fe composite, which exhibits excellent microwave absorption properties, is generated simultaneously. The minimum reflection loss (RLmin) of the solid product reaches &minus:54.78 dB at 15 GHz with an effective absorption bandwidth of 4.5 GHz at the thickness of 1.57 mm.
