Hydrogen-rich superhydrides are believed to be very promising high-Tcsuperconductors as they are expected to mimic characteristics of metallichydrogen. Recent experiments discovered superhydrides at very high pressures,e.g. FeH5 at 130 GPa and LaH10 at 170 GPa. With the motivation of discoveringnew hydrogen-rich high-Tc superconductors at lowest possible pressure, here wereport the prediction and experimental synthesis of cerium superhydride CeH9below 100 GPa in the laser-heated diamond anvil cell. Ab-initio calculationswere carried to evaluate the detailed chemistry of the Ce-H system and tounderstand the structure, stability and superconductivity of CeH9. CeH9crystallizes in a P63/mmc clathrate structure with a substantially dense3-dimensional hydrogen sublattice at 100 GPa. These findings shed a new lighton the search for superhydrides in close proximity with atomic hydrogen withina feasible pressure range. Discovery of superhydride CeH9 provides a practicalplatform to further investigate and understand conventional superconductivityin hydrogen rich superhydrides.
