Such information will be available in the 'instruction to authors' web page. Many journals ask for list of referees and some they pick and chose their own referees.
I am editor-in-chief of a journal. Sometimes, it is very difficult to find a reviewer who would accept to review your paper. In such case, reviewer suggestion would come in handy. Among the 3 referees or so that you provide, the journal editorial office would chose to invite one referee. Sometimes, they entirely skip this idea.
On the other side of the story; when the reviewer's are requested, there are some ethics needs need to be followed:
a. they should not be be current or former collaborators (e.g. students/mentors) of all the authors of the paper in question.
However, invariably what happens is that most of the authors provide the names of the people who exactly fall within that category. This is the issue that the journals are reluctant to provide other names. Ultimately the editorial department goes with their own choices of referees.
Many times, my papers get delayed in reviews, then if I were to contact the editorial office, I would receive similar response from the editor. In addition, in my own journal, we never ask for reviewers in the past. But we have started asking people to furnish the list of potential reviewers. Sometimes, this could speed up the process. However, we would cautiously move if we go with their suggestion or not based on our own research.
Finally, you could always suggest the names of people who you do not want to review your paper. They might have conflict of interest or personal academic rivalry. However, you might send a confidential note as to why your paper shouldn't be reviewed by them.
The following might not be a valid criteria: "This person is highly knowledgeable and accomplished in the field of my expertise and he/she might ended up rejecting my paper. That's the reason why I don't want them to review my paper".
A number of Elsevier journals provide for authors to suggest reviewers for their manuscripts. However, there are ethics to be observed in making such suggestions and the journal is not bound to use any reviewer you suggest. You will find the requirement for suggesting reviewers and the relevant links for guides on the manuscript submission platform when you are making your submission. Some journals also allow you to specify persons you do not want to review your manuscript.
It depends to which Elsevier journal do you submit your research paper. As per my recent experience, when I submitted my manuscript for publication consideration to Safety and Health at Work, an Elsevier journal, they asked me to submit names of two reviewers. However, I think they usually they don't send the manuscript to the reviewers which we select rather they send to their own reviewers. Whether it is compulsory or not to give the names of reviewers will be guided by their online portal.
