Developing room-temperature superconductors is the ultimate goal of superconducting research field. Recent work focus onthe development of high-temperature superconductors in hydrogen-rich materials under high pressure. Sulfur hydride (H3S) and lanthanide hydride (LaH10) with superconducting transition temperatures (Tc) of >200 K are theoretically predicted and then experimentally confirmed. Hydrogen-rich materials are considered as one of optimum candidates for room-temperature superconductors, thus becoming a hot research aspect in physics and materials. Some contributions in this aspect were achieved involve a variety of new cage-like superhydridesPrH9 and NdH9 are synthesized under high pressure, and their Tc is determined, The magnetic properties of NdH9 are discovered and its magnetic properties suppress a superconductivity; Novel cage-like superhydrides of CaH9 are designed under high pressure, and its Tc is predicted to be 266 K; superconducting zirconium hydrogen compounds ZrH3 and Zr4H15 are synthesized under mild pressure conditions by experimental and theoretical studie; The binary hydrides are extended to ternary hydrides, and MgXH6 (X=Si, Ge) with Tc of 60 K are designed.
