This invention provides a self-supporting one-dimensional nanorod array composite material, its preparation method, and its application, belonging to the field of clean energy harvesting technology. The preparation method provided by this invention includes the following steps: mixing soluble nickel salt, soluble molybdate, and water, and carrying out a hydrothermal reaction to obtain a NiMo precursor; heat-treating the NiMo precursor and a modifier under a protective atmosphere to obtain the self-supporting one-dimensional nanorod array composite material. Experimental results show that the composite material prepared by the method provided by this invention has excellent electrocatalytic water splitting activity and operational stability, and photo-assisted synthesis further enhances the electrocatalytic water splitting activity of the composite material, making it applicable to solar-driven electrocatalytic water splitting.

The application relates to the field of photocatalytic conversion, and discloses a noble metal-loaded amorphous metal oxide catalytic material and a preparation method and application thereof. The catalytic material comprises a group VIII amorphous metal oxide and ruthenium; the group VIII amorphous metal oxide is at least one selected from amorphous nickel oxide, amorphous cobalt oxide and amorphous iron oxide; and the content of the ruthenium is 0.1-6.5% in mass based on the total amount of the catalytic material in terms of elements. The catalytic material provided by the application simultaneously contains noble metal and amorphous metal oxide, the rich coordination unsaturated structure of which can provide surface reaction active sites and improve reaction efficiency.
