Sine wave becomes triangular wave after operational amplifier. I used 358 single power supply with 12V bias and 6V output peak value of about 9V, and it becomes triangular wave.
sine wave to triangle wave is a typical manifestation of insufficient Slew Rate.

the so-called "slew rate" means that the change speed of the signal output by the operational amplifier has a limit slope, and the voltage can only rise or fall below this slope, and the slew rate unit is usually V/uS.

the solution can only be changed to a higher speed operational amplifier.
