Figure 1 In situ Generation of Ni-Nanosheet-Based Electrocatalyst for HER and Identification of the Molecular Nature of its Catalytic Activity (A–C) Transformation of HER electrocatalyst from (A) Ni(OH)2 nanosheets to (B) Ni-BDT nanosheets, which were eventually in situ electrochemically activated to become (C) Ni-BDT-A nanosheets. (D) The HER electrocatalyst comprised mainly Nio active species and a small amount of trace surface sulfide (Sadδ−), as characterized by in situ X-ray absorption spectroscopy.
