There are two possible ways in which you could read the intent of the original sentence:
(1) Because there is increased demand FOR scientific research - in other words, society/business/whoever else is calling for more scientific research to be performed - platinum costs more.
(2) Because there is increased demand [FOR platinum] IN scientific research, platinum costs more.

The first of these interpretations is absurd: it's a total non-sequitur, since a call for more science won't directly affect the price of a specific good like platinum.  The second interpretation, on the other hand, makes perfect sense.

In any case, it boils down to understanding the idiomatic usage: demand FOR X means that X itself is what's desired, whereas demand IN X means that something else is demanded to satisfy the interests of field/endeavor X.
