摘要The Co3O4 nanosheet-built hollow dodecahedrons (Co3O4 NSHDs) were fabricated via a controllable two-step self-templated method. The ZIF-67 dodecahedrons were prepared as first self-template to synthesize the Co-LDH hollow dodecahedrons, which were further used as self-template to fabricate Co3O4 NSHDs by a controlled calcination. The proposed two-step self-templated method not only brings hollow structures without auxiliary template, ultrathin nanosheet, ultrafine grains, and large surface areas, but also allows the easy and uniform surface modification, as demonstrated of PdO modification. The Co3O4 NSHDs with above features could show multifunctional applications, such as sensing and catalysis. Experiments suggest that the Co3O4 NSHDs show good gas sensing performances to trimethylamine at a low operating temperature (100 degrees C). They can be further enhanced by PdO surface modification, which have a low detection limit (250 ppb) and a short response time (4.5 s). In addition, the Co3O4 NSHDs exhibited excellent oxygen evolution reaction performances with a low overpotential of 359 mV, low Tafel slope of 80.7 mV dec(-1) and low electrochemical impedance, which was superior to those for the Co3O4 NCs obtained by directly calcinating the ZIF-67 templates, Ni foam and most common metal oxides catalysts.
