Abstract: A display method is applied to a display apparatus including a display panel, a display driver chip, and a microprocessor. The display method includes outputting, by the display panel, a scanning-done signal of a first frame image generated after scanning rows of pixel circuits of the display panel; after the microprocessor or the display driver chip receives the scanning-done signal, writing, by the display driver chip, initial data of a second frame image provided by the microprocessor and outputting, by the display driver chip, display data of the second frame image to the display panel based on the initial data; or outputting, by the display driver chip, the display data of the second frame image to the display panel in response to the scanning-done signal, the display data being generated based on the initial data provided by the microprocessor. The second frame image follows the first frame image.

Abstract: A method for producing 2,5-furandicarboxylic acid (FDCA) by electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) is provided, where the catalytic oxidation is conducted using an electrolytic cell; the electrolytic cell is a three-electrode electrolytic cell or a two-electrode electrolytic cell; an anode used is a monolithic electrode; the monolithic electrode includes a carrier and a catalytically active substance loaded on the carrier; and the catalytically active substance includes cobaltosic oxide particle-encapsulated nitrogen-doped carbon nanowires. The method has high activity and high selectivity, and the anodic catalyst is highly tolerant to HMF.

Abstract: A cobalt catalyst and a preparation method thereof are provided. The cobalt catalyst includes a carrier and a catalytically active substance; the carrier is a cobalt-based substrate material; the catalytically active substance is grown on the surface of the carrier, and the catalytically active substance has a morphology of hydrangea-shaped nanospheres. The cobalt catalyst is an autogenously grown monolithic nanosphere catalyst with a three-dimensional structure assembled by nano-sheets on the catalyst surface. The cobalt catalyst has a high specific surface area and can fully expose the catalytically active sites to enhance the catalytic efficiency. Compared to a nanowire catalyst, the cobalt catalyst has better self-supporting properties, and the active components are not easily aggregated nor fall off during a use process. Therefore, the cobalt catalyst has a longer service life.
