In situ transformation of Co-MOF nanorods into Co3S4/Ni3S2 nanotube arrays for electrochemical biomass upgrading

The in situ transformation of one-dimensional (1D) Co-based metal–organic framework (Co-MOF) precursors into Co 3 S 4 /Ni 3 S 2 nanotube arrays on nickel foam (NF) was realized by ion exchange and synchronous etching via solvothermal sulfurization.
