Arsenal started the second half strongly and had a Mikel Merino goal ruled out for offside.
Donnarumma also made more saves to deny the hosts.
PSG should have given themselves a bigger cushion for the second leg but Bradley Barcola and Gonçalo Ramos both squandered gilt-edged chances late on.
The second leg will take place in Paris next Wednesday with the winners facing either Inter Milan or Barcelona in Munich.
