It is a matter of high significance to develop on-demand H2 evolution from chemical hydrogen storage materials for efficiently avoiding the safety risks and costs in process transport, which has important scientific application value safe effective use H2. In this study, we have designed synthesized an RuCo nanocatalyst immobilized onto hollow carbon nanocuboids (RuCo-CNCs) (including Me2NHBH3, NH3BH3, NaBH4). Full physical characterization confirmed that RuCo-CNC-800 exhibited nanocuboid-shaped structure, bimetallic nanoparticles were successfully nanocuboids. This advantageous prevent aggregation mass transfer, hence boosting its stability catalytic performance evolution. More importantly, situ was applied hydrogenation reaction, thus eliminating need dangerous cylinders. addition, "on–off" switch Me2NHBH3 hydrolysis over achieved using system Zn2+/ethylenediaminetetraacetic acid disodium salt (EDTA-2Na). work not only provides efficient but also suggests feasible method
