Hydride ion (H⁻), with their low mass and high redox potential, are considered promising charge carriers for next-generation electrochemical devices. However, the lack of efficient electrolyte with fast hydride ion conductivity, thermal stability, and electrode compatibility has hindered their practical applications.In a study published in Nature, Prof. CHEN Ping's group from the Dalian Instit...
Recently, Professor Chen Ping and Professor He Teng from our research group at the Dalian Institute of Chemical Physics, in collaboration with Associate Professor Rao Li from Central China Normal University, have made new progress in developing metal-organic compounds for hydrogen storage materials. For the first time, they utilized photocatalysis to achieve reversible hydrogenation and dehydro...
On January 10, 2025, a 150 tons/year magnesium hydride pilot project was launched. The project is a joint initiative involving the Yulin Zhongke Clean Energy Innovation Research Institute as the construction supporter, our research group as the technology provider, and Dalian Fude Jinyu New Energy Co., Ltd. as the private investor. The pilot plant has begun trial operations and produces high-qu...
Recently, a team led by Professor Chen Ping and Professor Cao Hujun discovered a peculiar "freezing effect" in lattice-distorted lanthanum hydride, whereby temperature treatment can cause its electronic conductivity to irreversibly decrease by 2 to 3 orders of magnitude. They revealed that this mutation is related to changes in the coordination environment of tetrahedral hydrogen.The high polar...
Recently, a team led by Professor Chen Ping and Professor Guo Jianping in our group has made new progress in hydride chemical nitrogen fixation research. They have revealed the relationship between the photodehydrogenation color change phenomenon of lithium hydride (LiH) and nitrogen fixation, thus constructing a LiH-mediated photocatalytic ammonia synthesis process.The synthesis of ammonia thr...
Recently, a team of researchers led by Professor Chen Ping and Professor Guo Jianping in our group, in collaboration with a team of Professor Xi Zhenfeng from Peking University, developed a method for synthesizing a variety of important nitrogen-containing organic compounds from nitrogen through a research paradigm that cross-integrates homogeneous and multiphase processes.The efficient activat...
Recently, our research group collaborated with a team of Associate Professor Wu Anan from Xiamen University and found that alkaline (earth) metal hydrides, such as lithium hydride (LiH), can mediate the hydrogenolysis of aniline C-N bonds to generate benzene and ammonia (abbreviated as CL-HDN) through a chemical looping, in which the nucleophilic attack of hydride ions (Hˉ) on the benzene ring...
Recently, our research group was invited to publish a review article on ion migration in hydrides.Hydrides are hydrogen/energy carriers with potential applications in chemical conversion, hydrogen storage, heat storage, ion conductivity, etc.The radius of the H- ion of hydrides is close to that of O2-, but they have less charge, special coordination, and are easy to polarize. These structural...
