  • Publication number: 20210316286
    Abstract: The present disclosure discloses a core-shell structured NiSe2@NC electrocatalytic material having a general formula of NiSe2@NC. The present disclosure also provides a preparation method and use of the catalytic material. In the present disclosure, hydrazine hydrate is used as a reducing agent, selenium powders are used as a source of selenium, and a metal-organic framework (MOF) is used as a precursor. Selective selenization of mixed-linker MOFs based on mixed ligands is carried out through a hydrothermal reaction. Then, a series of adjustable N-doped carbon-coated NiSe2 nano-octahedrons are prepared through a one-step calcination reaction. By adjusting the types of mixed ligands in the MOF, carbon-coated nickel diselenide composites doped with different pyridinic-N contents can be obtained. Corresponding electrochemical tests prove that, the electrocatalytic activity has a strong correlation with the content of pyridinic-N.

  • Patent number: 11144871
    Abstract: In optimized container management system, a booking request with customer locations, booking time, container type, movement mode, depot locations and depot locations stock information are received as input in a solver in a container management system received in a container management system. Based on the movement mode of booking request received by customer, solver algorithm is invoked to build a bipartite graph. A bipartite graph with nodes representing customer locations and depot locations are generated, based on the movement mode. Edges between the customer locations and the depot locations are generated based on a container balancing criteria of a solver algorithm. For remaining booking request, edges between the customer locations and the depot locations are generated based on a cost minimization criteria of the solver algorithm. The depot locations are assigned to the corresponding customer locations based on satisfying the container balancing criteria and the cost minimization criteria.
