Q: I am confused about which topic I should focus on and which topic I should continue working on for research

In today’s competitive world, settling on a novel research topic is becoming increasingly challenging, so originality is most imperative. Skimming through scientific literature on a regular basis will aid in identifying an interesting topic related to the subject of your choice, which you have mentioned to be computational study of metal nanoalloy clusters. That way, you can avoid choosing similar topics and gain better exposure to novel reported findings. Think about what specifically interests you in the computational studies of nanoalloys, and try to focus on the same for a more refined topic. 

Consider what you need to undertake for this topic, in terms of experiments or theoretical calculations needed, timeline, budget, etc. Given your research topic is broad, you can focus on a specific aspect of the same to make your research crisper.  You may also want to consider if the results will be as you expected and if the findings you intend to publish will be of interest to scientists in the related fields.
