Is this correct for non-inverting op-amp?
Without an impedance from Vin- to ground this is a unity gain amplifier with no intentional frequency shaping. The 100k passes the output to Vin- and because it isn't attenuated - this circuit IS a unity gain amplifier. No amount of shunting the 100k with the 100nF capacitor is going to make a difference.

EDIT to show a 2nd order Sallen Key Low pass filter
If you need a decent non-inverting filter I can recommend the unity gain sallen key filter and in particular this site. Here's the values I plugged-in for a 15Hz low pass filter: -



For single supply operation the values are still good except you need to create a mid rail point that is suitable for your signal to be referenced to. It's probably a good idea to use another op-amp set as a unity gain non-inverting configuration with a resistor to Vsupply + and a resistor to Vsupply -. This forms a potential divider that creates your 0V midrail supply. If you look at this document page 9 onwards has also got some decent ideas about creating a split power rail.

You can also look at this site for ideas - look for "THE OP-AMP AS A VOLTAGE FOLLOWER" - feed the junction of the two resistors (mentioned above) onto the input and you get a steady output that equals half rail.

If you need confirmation of what the circuit looks like here is another reference in figure 2. Good luck.
