▎ 摘　　要

NOVELTY - The electric heater has a thermal catalyst layer formed on the surface of the metal heating components. The heat dissipation layer includes a volatile organic thermal catalyst. The volatile organic catalyst is used to catalytically decompose volatile organic matter in the environment at the temperature provided by the heating component. The heating component comprises a metal heating piece and a thermal catalyst sheet. The metal heating sheet is provided with a surface heating piece. The thermal catalytic layer includes graphene piece. The volatile organic matter heat catalyst included a noble metal catalyst and a non-noble metal catalyst. USE - Electric heater for heating metal heating piece and thermal catalyzing layer. ADVANTAGE - The heat-catalyzed layer is set on the surface heating piece it can use itself to be in high temperature working state of metal heating to piece a suitable catalytic condition for the heat catalytic layer catalytic volatile organic matter, without need to be heat catalyzed layer that is additionally set with a heating or resistor saves the production cost and reduces the use energy consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method for heating metal heating piece and thermal catalyzing layer. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of electric heater for heating metal heating piece and thermal catalyzing layer. Electric heater heating component (100) Connecting piece (110) Good thermal conductivity heating piece (120)
