You cannot revoke what was never yours to issue in the first place. The government is the only entity that can revoke a Green Card. It is illegal to use immigration laws to gain an unfair advantage in civil matters. If she has a green card, it is because you sponsored her into the US, but the law makes her wait 2 years in order for the marriage to be considered a good faith marriage. The only thing you can do is to not co-sign the I-751 application to remove the condition on LPR. Your spouse will have to explain your absence at the interview and your unwillingness to co-sign the I-751.

You can notify the Service Center where your case was filed as well as the office where either her immigrant visa was issued or she received adjustment of status. Depending upon what stage of processing, your wife may still be able to enter the U.S., but would likely receive a notice of intent to revoke the approved case. This is the first step in a process that can result in revocation of her status.

The US citizen has no authority to revoke anything. If there is a concern regarding fraud in the marital relationship, contact Citizenship and Immigration Services and/or Immigration and Customs Enforcement and provide a "tip" as to the alleged fraud. Unfortunately, the system which is set up to target fraud is not all that useful when the case involves individual cases. Instead, the federal government spends far too little time trying to root out fraud on a case by cases basis. Instead, the government is more interested in large scale rings of fraudulent activity rather than the cases of one on one sham relationships. Nonetheless, there are resources out there. CIS operates a unit called the Fraud Detection National Security office and it is supposedly involved in investigating cases such as these, supposedly there are officers assigned to each USCIS Field Office whose responsibility it is to listen to complaints and to investigate the same. As a practitioner, I believe that far too little is done to go after individual case fraud and unfortunately, many sham marriages go undiscovered and individuals obtain immigration benefits which should have never been provided. Take some time, do what you can to report bona fide cases of fraud and hope for the best.

This is going to be a very fact specific situation, but generally speaking it is up to the USCIS to make a determination as to whether there has been marriage fraud. A US citizen spouse can alert the USCIS to his or her concerns, but from there it is up to the USCIS to determine what should happen next.
