Construction of [NbO]6−x‐xS Structure to Change Charge Density and Regulate Spontaneous Polarization to Achieve Efficient Pyro‐Photo‐Electric Water Splitting System of NaNbO3

Pyroelectric materials in the field of photoelectrochemical (PEC) water splitting still face the problems of difficult low spontaneous polarization intensity and excessive carrier recombination. Based on the above problems, we altered the interaction between S-Nb-S in the [NbO]
