Unfortunately, this week, there was a bit of confusion as one Microsoft support document stated TPM 1.2 was the minimum requirement for Windows 11. In contrast, another hardware requirements page said it was TPM 2.0.

Microsoft support doc that stated TPM 1.2 was compatible
This conflicting information has since been fixed by Microsoft, who clarified to BleepingComputer that Windows 11 requires TPM 2.0.

Windows 11 won't work without a TPM - What you need to know
Windows 11 requires a TPM 2.0 security processor to install or upgrade to Windows 11. Unfortunately, mistakes in support documents have causes conflicting information on what type of TPM you need and why you need it in the first place.
