I have a standby server which is kept aside  for using in case my exchange server goes down. My present exchange server is also a domain controller. Please let me know whether i can export only active directory from my present server and import to my standby server.

if you connect your standby DC to the network, AD data will replicate automatically.  you cannot just copy AD data form one server to another one

you can export and import (to your standby server) your users with the csvde tool: http://www.computerperformance.co.uk/Logon/Logon_CSVDE_Export.htm$

What exactly are you trying to achieve?

If your primary server goes down (which is also running Exchange) then you will have to restore the server AD & Exchange to get it back up and running. You could restore the AD part on it's own but you will still have to recover Exchange.

If the DC goes down and there are no other DC's then you cannot install a secondary DC as poart of the domain - you need a functioning DC with the FSMO roles to do this.

You could install a secondary server as a DC in a new domain and manually create the users - This would not be of much use though as the accounts would have the same name but different Security Identifiers (SID's), the accounts would not have the same permissions and rights as the previous.

The following article gives reference in restoring the DC to different hardware:

You cannot use a cold standby server (a server that is not powered on) as a domain controller and expect to have things work.  Active Directory has constant changes, including changed passwords, account information (including Exchange Mailbox information), group membership, OU configuration, etc, etc.  Exporting the users will do you little good - if any.  If you have two servers make the second one a domain controller and leave it on.  Unless you're using DoubleTake or Neverfail as we discussed in one of your previous questions.

I think neverfail will be a good solution.
