Synthesis of Nanoporous Molybdenum Carbide Nanowires Based on Organic-Inorganic Hybrid Nanocomposites with Sub-Nanometer Periodic Structures

摘要

Transition-metal carbides have attracted much attention as promising materials for their outstanding bulk and surface physicochemical properties originating from the unique metal-carbon chemical bonds and noble-metallike d-state density around Fermi level, such as thermal stability, mechanical hardness, superconductivity and high catalytic performance in hydrocarbon conversion. Traditionally, they were synthesized via the temperature-programmed reduction (TPRe) method which employs the gas-solid reactions between oxides and the mixture of hydrogen and carbon-containing gases including CH4, C2H6, C3H8, and C4H_(10). However, incomplete transformation is difficult to be avoided since the reactions take place only on the gas-solid interface.
