DC-DC boost converter not working as it should
A boost converter stores energy (in the first half of the switching cycle) in an inductor and then releases that energy to the load in the second half of the switching cycle. The energy it stores (and how often it repeats this process every second) HAS to match the power required by the load in order to sustain the correct output voltage.

In other words, in its basic form, it's a power regulator and not a voltage regulator.

So, a boost converter (without a sophisticated feedback system to control duty cycle) is a power regulator AND, without a load it will continue to dump that inductor energy into the output capacitor until that output capacitor gets so charged up it breaks or the output transistor starts to break down.

You need to have the correct load to match the duty cycle to maintain the output voltage at your desired level. It's not a voltage regulator until you apply a level of sophistication and negative feedback.

The diode is very important - for instance the 1N400x series has an appalling switch off time in several tens of micro seconds and if your operating frequency is tens of kHz it will behave very badly.

C1 at 1,500 uF sounds very much too high unless your switching frequency is a few hundred Hz then, 94 uH sounds too low.
