There are many ways to approach this, but it depends on your workflow.

You can proceed and apply a "Corona ShadowCatcherMtl" to your plane, change your Alpha mode to "For Compositing".

On your render settings change your "Render Selected" mode as view-port selection, select your plane and press render.

On your alpha channel you should only be able to see the shadow being cast from your object to the plane, save as png,tga or tiff with alpha channel.
