Try the following code
<img t-att-src=”’/report/barcode/ QR/’ + ‘upi:/’ + ‘/’ + ‘pay……..’>

To include // after upi: in an HTML attribute, you need to properly escape the characters so that they are interpreted correctly. In HTML, the colon (:) and slashes (/) have special meanings, so they need to be represented by their corresponding HTML entities.
