The growth of ultrathin 1D inorganic nanomaterials with controlled diameters remains challenging by current synthetic approaches. A polymer chain templated method is developed to synthesize ultrathin Bi2O2CO3 nanotubes. This formation of nanotubes is a consequence of registry between the electrostatic absorption of functional groups on polymer template and the growth habit of Bi2O2CO3. The bulk bismuth...
Here, the synthesis of a series of pure phase metal borides is reported, including WB, CoB, WCoB, and W2CoB2, and their surface reconstruction is studied under the electrochemical activation in alkaline solution. A cyclic voltammetric activation is found to enhance the activity of the CoB and W2CoB2 precatalysts due to the transformation of their surfaces into the amorphous CoOOH layer with a thickness...
